A Little Snow to End February

As the headline implies, we’ve got some of the flaky white stuff on the way. This storm is going to be unlike any storm we’ve had all winter. It’s going to be all snow, and the fluffy type at that. It also, may cause problems for your Thursday morning drive to work or school.

High pressure is in place right now, with a cold and dry airmass settled into New England. Temperatures dropped into the single numbers and teens this morning, and at midday, dewpoints were still well below zero. As the high moves off the east, an Alberta Clipper will move in from the west. As it starts to spread precipitation into the region, it will run into this dry air this evening. So, even though the radar may show snow falling, it will evaporate before it hits the ground.

Very dry air remains in place at midday. This will help delay the snow’s arrival a little this evening. Image provided by WeatherBell.

Eventually, the atmosphere will moisten up enough so that the snow will make it down to the ground, and we’ll have some light fluffy snow falling through the overnight hours. It should taper off and end from the west to east right around the time most people head out to work or school in the morning. Road crews should have plenty of time to work on the getting everything cleared before the morning rush hour, but this being New England, where plenty of people completely forget how to drive as soon as they see a single raindrop, well, the snow will probably impact your morning drive, so leave a little extra time.

As for how much will fall, this won’t be a big deal, at least by New England standards. Most of the snow maps you see people post online (like the one below) assume a 10:1 ratio for snow to liquid. In many cases, this will work – 1 inch of rain equates to 10 inches of snow. However, the colder you get, the more the ratio changes. With temperatures in the teens, the ratio could be 20:1. For tonight’s storm, the ratio will probably end up somewhere around 15:1, so, you might expect a little more than the map below is showing. Remember – I also said that the initial burst of snow will likely evaporate before reaching the ground. The model assumes that anything showing up as precipitation does reach the ground, so it will assume we’ve got more precipitation than we actually will get. Plus, nearly every storm this winter has underperformed in the snow department, compared to what the models have forecast. So, factoring all that in, the 10:1 map may actually not be that bad after all.

OK, enough of the caveats and explanations, all you want to know is how much you’ll be cleaning off of your car or driveway in the morning.

Southern New Hampshire: 1-2″
Merrimack Valley/North Shore/Cape Cod/South Coast/Rhode Island: 1-3″
Metro Boston/MetroWest/South Shore: 2-4″

Given the fluffy nature of the snow, if a few places picked up 5″, especially from Worcester County into the South Shore, we wouldn’t be completely shocked.

Another weak system will pass to our south Thursday night into Friday morning, with some light snow possible across the South Coast and Cape Cod, but the storm may end up too far south to impact us at all. Another system passes to the north late Saturday into early Sunday, and this one will be more typical of what we’ve seen this winter, with some light snow changing to sleet, freezing rain and eventually rain. What we’ve actually got our eyes on in the future is Sunday night and Monday. The models have been signalling for a few days the potential for a system to impact us then, but the details have been all over the place. The various models have shown solutions that range from a complete miss to snow to rain, to a heavy snowstorm. There’s still plenty of time for that to come into focus, and we’ll worry about it more as the weekend arrives. For now, we’ll just deal with the light snow tonight.

Weekly Outlook: February 18-24, 2019

You’re waking up to snow this morning, but that might not be the only snow for the week, at least for most of us. It is still February, so this should be expected.

The week is starting off with some snow, but since we discussed that in detail yesterday, and the bulk of the snow will be over by the time most of you read this, we won’t dwell on it much longer. Snow showers will continue into the afternoon, but little additional accumulation is expected. High pressure then builds in for tonight, Tuesday and part of Wednesday. This will give us drier but colder conditions. Again, it is February, this should be expected.

It’s still winter, so it shouldn’t be that warm. Average high temperatures for mid-February are in the upper 30s to lower 40s. Image provided by Weathermodels.com

By late Wednesday, another low pressure system will head towards the Great Lakes, just like a lot of them have already done so far this winter. As a result, we’ll see the same thing we have already seen plenty of times. Snow will develop Wednesday night, then warmer air will move in aloft, with a change to sleet and/or freezing rain early Thursday, and an eventual change to all rain as warmer air finally moves in at the surface. This doesn’t look like a big deal, with an inch or two of accumulation possible Wednesday night from the Merrimack Valley into southern New Hampshire.

A little bit of snow is expected early Thursday morning, mainly north of Boston. Image provided by Pivotal Weather.

The rain ends Thursday morning, then high pressure returns for later Thursday into Friday and Saturday. Then on Sunday, we do it all over again. Low pressure heads towards the Great Lakes again, and we get some snow, changing to sleet and/or freezing rain, then plain rain. Wash, rinse, repeat.

Monday: Cloudy with occasional snow showers tapering off and ending. High 27-34.

Monday night: Clearing. Low 9-16.

Tuesday: Partly to mostly sunny. High 24-31.

Tuesday night: Becoming partly to mostly cloudy. Low 9-16.

Wednesday: Cloudy with snow developing in the evening, changing to sleet, freezing rain, and rain from south to north overnight. High 25-32.

Thursday: Rain ending in the morning, then becoming partly sunny and breezy in the afternoon. High 42-49.

Friday: Intervals of clouds and sunshine. High 36-43.

Saturday: Some early sun, then becoming mostly cloudy. High 37-44.

Sunday: Cloudy, snow developing, quickly changing to sleet or freezing rain, then plain rain in the afternoon. High 40-47.

Monday Morning Mess?

While you’re enjoying a sunny Sunday, we’ve got some snow on the way tonight into Monday. It won’t be a lot, but it’ll probably make your morning drive to work into a large headache, especially south of Boston.

Low pressure will move out of the Ohio and Tennessee Valleys today and head east-northeastward, passing south of New England Monday morning. For once this season, we have enough cold air in place and a favorable storm track that we’ll be talking about all snow with this system, except possibly across parts of Cape Cod and the Islands. Since this is a fairly weak storm, we’re not talking about a lot of snow to begin with, and with it passing well to the south, the amounts will taper off quickly, the farther north you go.

The high resolution NAM model has a pretty good handle on how this storm will go, on our opinion. Loop provided by Tropical Tidbits.

The snow will develop late this evening from west to east, roughly in the 10pm-midnight time frame. It will continue through the overnight hours, and may even be briefly moderate to heavy south of Boston. While the steadiest snow looks to end during the morning hours on Monday, occasional light snow and snow showers will continue off an on during the afternoon, especially along the coastline. Everything should be done by evening.

So, how much are we looking at?
Southern NH/Southern ME: 1″ or less
Merrimack Valley: 1-2″
North Shore/Metro West: 1-3″
I-95 Corridor (Boston/Providence): 2-4″
Southeastern Mass/Southern RI: 3-6″, possibly a little more across Cape Cod

We’ve stuck with the high-resolution NAM for much of the winter, and it’s done pretty good, so we see no reason to go against it now. Image provided by WeatherBell.

Another storm may bring in more snow towards Wednesday, but we’ll have more details on that in our Weekly Outlook early Monday.

Weekly Outlook: February 11-17, 2019

Remember a few years ago when every single storm turned into a major snowstorm around here? In many ways, that was preferable to the winter we’ve had this year. Forecasting was a lot easier. Just forecast snow, and lots of it. Chances are, that’s what ended up happening. Not this year. This year, we get rain/snow lines, sleet, freezing rain, and a general mess with just about every storm. Well, there’s another one on the way.

The week actually starts out on a quiet note with high pressure to the north and a weak low pressure area passing well to the south. This will provided us with dry and seasonably cold conditions today. This is the proverbial “calm before the storm.” On Tuesday, low pressure will start to head towards the Great Lakes, sending clouds and precipitation into New England. It should be cold enough for it to start as snow across the region Tuesday afternoon. In fact, the snow may be quite heavy for a while Tuesday afternoon, which may result in the afternoon rush hour becoming utter chaos (not that it isn’t already). Eventually, warmer air will start to move in aloft, and then at the surface, which will result in a change to sleet and then freezing rain or rain from south to north during the evening hours. The questions are: 1. When does the change to sleet occur? 2. How long does it stay as sleet before changing to freezing rain? 3. When do temperatures get above freezing to end the icing threat? The answers to these questions will play an important role in how much of a mess things become.

The NAM may be a little quick to bring in the sleet, and it has a lot of sleet, but it’s done fairly well this winter, so far. We’ll see how it does with this storm. Loop provided by Tropical Tidbits.

Eventually, a secondary area of low pressure will develop, and move across southeastern New England early Wednesday. This should allow most of the region to get above freezing and change to plain rain before everything winds down around daybreak Wednesday. So, how much snow are we expecting before the changeover?

Cape Cod/Southeast Massachusetts, Southern Rhode Island: 1-2″
I-95 Corridor (Boston/Providence): 1-3″
MetroWest/North Shore: 2-4″
Merrimack Valley/Southern NH/ NH Seacoast: 3-6″
Central NH/Southern ME (Concord/Portland): 4-8″

The FV3 model is probably closest to our thinking for snowfall amounts. Image provided by Pivotal Weather.

High pressure builds in behind the storm for late Wednesday and Thursday with dry and cooler conditions. However, another storm follows for Friday. This one looks to be milder, with mainly rain. However, it’s still 5 days away, and the models have been, well, not good, beyond about 3 days this winter, so we’ll obviously have to keep an eye on that one too. But for now at least, it looks like rain. High pressure builds in behind that storm next weekend with dry and colder weather.

Tuesday might suck weather-wise, but cheer up – pitchers and catchers report to Fort Myers for Spring Training on Wednesday! There will be actual games a week from Friday! Oh, and in case you forgot, the Patriots won the Super Bowl last week! Image provided by NESN.

Monday: Morning clouds, then becoming partly sunny. High 31-38.

Monday night: Clouds return. Low 13-20.

Tuesday: Cloudy with snow developing in the afternoon, possibly heavy at times. Snow will change to sleet along the South Coast towards evening. High 25-32.

Tuesday night: Snow changing to sleet, freezing rain, and eventually plain rain from south to north before ending by daybreak. Breezy. Temperatures slowly rise at night.

Wednesday: A lingering snow or rain shower is possible, otherwise skies will become partly sunny, breezy. High 39-46, possibly warmer across parts of southeastern Massachusetts and Cape Cod in the morning.

Thursday: Sunshine and a few clouds, still breezy. High 34-41.

Friday: Becoming partly to mostly cloudy with a few rain showers possible. High 43-50.

Saturday: Cloudy and breezy with a chance of rain. High 43-50.

Sunday: Partly to mostly sunny, breezy, and colder. High 29-36.

Weekly Outlook: January 28 – February 3, 2019

The winter of little snow rolls on this week, with just a little bit of snow and more cold weather. Don’t worry, it won’t last too long, and it could be a LOT worse.

The week starts off with high pressure building in, giving us sunshine and seasonably cold conditions. Clouds will start to move in during the evening as low pressure heads towards the Midwest. As this system moves across the Great Lakes on Tuesday, snow will develop across the region Tuesday afternoon. A secondary area of low pressure will develop across the Mid-Atlantic states during the afternoon. This will help bring milder air into the region, changing to snow to rain during the afternoon and evening hours. Whether or not this changeover makes it into southern and central NH is still a question mark. Either way, this doesn’t look like a big snow producer, with a few inches across central and southern NH, and an inch or less elsewhere.

This storm is not expected to be a big snow-producer across the area. Image provided by Pivotal Weather.

Once that secondary low pressure area moves past the area, colder air will quickly move back in, changing any rain back to snow before it ends towards daybreak. That’s not the end of the story though. We could see some sunshine develop in the afternoon, but an arctic front will move through late in the day. This front may produce some snow showers or squalls, which could impact the Wednesday evening commute, but they may hold off until a little later. These squalls may briefly lower visibility, and could drop a quick half inch or so, but the bigger story is what comes in behind the front.

Wind chills will be well below zero when most of you are heading out to work or school Thursday morning. Image provided by Weathermodels.com

Skies clear out Wednesday night as high pressure builds in, ushering in much colder air. While it won’t be quite as cold as last Monday when most of the area had high temperatures around 5 degrees, we’ll have more wind this time, so wind chills will be well below zero on Thursday. So, how could it be worse? When this airmass moves into the Northern Plains and Upper Midwest later Tuesday into Wednesday, temperatures will be a LOT colder. Across parts of the Dakotas and Minnesota, low temperatures will drop near or below -40 Thursday morning, with afternoon highs not reaching -30 in some areas. This is actual air temperature, not wind chill. So what will the wind chills be? How does -60 to -65 sound? We’re not quite sure why people voluntarily live in this area, but they do.

Yes, wind chills could be lower than -60 in parts of the Upper Midwest and Northern Plains Wednesday morning. That is beyond ridiculously cold to us. Image provided by Weathermodels.com

Getting back to our weather, Thursday night will be chilly, but we’ll start to moderate on Friday as high pressure shifts to the east. Oh, it’ll still be cold, just not as cold as Thursday. The gradual warmup will continue on Saturday as high pressure moves offshore and then a warm front moves through on Sunday with milder weather moving in.

Monday: Mostly sunny and chilly. High 24-31.

Monday night: Increasing clouds. Low 15-22.

Tuesday: Cloudy with light snow developing in the afternoon, quickly changing to rain south of Boston. High 30-37.

Tuesday night: Light snow likely across central and southern NH, changing to rain from the MA/NH border southward during the evening. Rain changes back to snow everywhere after midnight, ending towards daybreak. Temperatures may rise a bit through midnight, then drop back to 22-29 by daybreak.

Wednesday: Breezy with any snow showers ending early, then skies become partly to mostly sunny. Snow showers or squalls are possible in the evening. High 26-33, but temperatures will quickly plunge at night.

Thursday: Partly to mostly sunny, breezy, and much colder. High 7-14.

Friday: Sunshine and afternoon clouds, still cold. High 17-24.

Saturday: A mix of sun and clouds, still chilly. High 22-29.

Sunday: Partly sunny and milder. High 34-41.

Storm Update – Less Snow, More Problems

In our forecast yesterday, we told you that some of the biggest questions were the track of the storm system and related to that, how far north the change to sleet/freezing rain would take place. Well, we’ve got some more clarity on that now.

Some of you are already seeing some snow falling this afternoon, but this is not related to the storm. Some ocean-effect snow has pushed into Cape Cod and Plymouth County, and will continue to push inland this afternoon. This will be light, with less than an inch in most spots. The steadier snow will move in late this afternoon and evening from the west, reaching southern NH and the Merrimack Valley first, then the rest of Eastern Massachusetts and Rhode Island. It’s after midnight where the changes start to take place.

The NAM model shows the progression of the storm with the changeover to sleet. freezing rain, and plain rain gradually spreading northward early Sunday. Loop provided by Tropical Tidbits.

The storm system looks like it will track a bit farther north, passing very close to Boston on Sunday. This will not only allow milder air to move into most of southeastern Massachusetts, but the milder air aloft will also move much farther north than we had anticipated yesterday. Snow will fall heavy at times overnight, especially north of the Mass Pike, but as the warmer air starts to move in, we’ll see a change to sleet and eventually freezing rain move into the South Coast towards Midnight. A change to plain rain is likely before daybreak across southern Rhode Island and southeastern Massachusetts, as temperatures may break into the 40s Sunday morning. Some of the rain could be heavy, which may wash away most of the snow that does fall. Farther north, snow will gradually change to sleet and freezing rain north and west of Boston towards daybreak, with the changeover likely getting into southern NH as well. This will significantly cut down on snow amounts, but could make travel quite hazardous if there’s enough freezing rain.

The NAM model is forecasting up to 1/4 inch of freezing rain in parts of southern NH and the Merrimack Valley. Image provided by Pivotal Weather.

By midday, the storm passes by and moves offshore, with winds shifting into the north. This will bring much colder air back in, and rather quickly. Temperatures may get close to or a little above freezing during the morning from southern NH into the Merrimack Valley and the northern and western suburbs of Boston, but by afternoon they’ll quickly drop into the 20s during the afternoon and teens by evening. That will result in a flash freeze, and any untreated surfaces will quickly freeze up, resulting in very hazardous travel. It will also mean that anything you haven’t cleaned off of your car, driveway, sidewalk, etc. will quickly turn into cement. The bitterly cold air will continue to flow in, and temperatures on Monday may struggle to reach the lower teens, with wind chills below zero thanks to gusty northwest winds. These gusty winds may also produce some ocean effect snow across parts of Cape Cod, especially the Outer Cape.

The High Resolution NAM model shows the rollercaster that our temperatures will be on over the next couple of days. Loop provided by Weathermodels.com

So, how much snow are we expecting now? Here’s our current thinking:

Cape Cod/South Coast: 1-3 inches
Southeastern Massachusetts/I-95 corridor: 2-4 inches
MetroWest/North Shore: 3-5 inches
Merrimack Valley/NH Seacoast: 3-6 inches
Southern NH: 4-7 inches
Central NH/Southern Maine: 8-14 inches, with higher amounts the farther north you go.

While there isn’t any one model that matches our current thoughts on accumulations, the High Resolution NAM model is closest to our current thinking. Image provided by the College of DuPage.

Temperatures will slowly start to moderate on Tuesday, then another system may move in on Wednesday, but this one, believe it or not, may be mostly rain. We’ll see how that evolves over the next few days.

The Party’s Over – Here Comes the Snow

We haven’t had a decent-sized snowstorm around here since late November. Well, that is about to end, much to the dismay of most of you. We’ve got several different concerns with this system, so we’ll try and touch on all of them.

Winter Storm Watches and Warnings are in effect for most of the Northeast with a Coastal Flood Watch for parts of the Massachusetts coastline. Image provided by Pivotal Weather.

We’ll start with what’s going on now. High pressure is building into Quebec, and this will bring cold air into the region. Tonight will be chilly, with lows in the teens, maybe even some single numbers. Meanwhile, low pressure is moving out of the Southern Plains. This low will move towards the Appalachians on Saturday, then off the Mid-Atlantic coastline Saturday night. This brings us to forecast problem number 1. Where does the low track from there? This is a critical point, as it will help determine what type of precipitation falls across the area. Some models keep the storm offshore, south of the Cape and Islands, while others bring it right across southeastern New England. We’re thinking it tracks pretty close to the Islands, but stays just to the south. By Sunday, it moves into the Gulf of Maine, and takes all of the precipitation away.

As for the timing of that precipitation, there’s not much disagreement among the models. Snow should move in during the evening hours (7-9pm) from west to east, and end during the afternoon (3-5pm) on Sunday, except across Cape Cod and parts of southeastern Massachusetts, where it may linger into Sunday night. The heaviest precipitation will likely fall between about 11pm Saturday and 8am Sunday, so if you don’t have to be out then, we’d recommend that you stay where you are.

The High-Resolution NAM model shows the progression of the precipitation across the region. Blue is snow, orange is sleet, purple is freezing rain, and green/yellow is rain. Loop provided by Weathermodels.com

What type of precipitation is going to fall? Well, that is a BIG question, that is still in doubt for a large portion of the region. It should start as snow for everyone. It will likely change to rain across Cape Cod and the South Coast, and parts of southeastern Massachusetts. In between? That’s where things get really complicated. As we usually see during storms, we’re going to have a “coastal front” set up. Basically, the milder air from the ocean will push inland a bit. If you are south and east of this coastal front, temperatures will be near or just above freezing. If you are on the other side of the front, temperatures will be in the teens. Eventually, this front will collapse to the coast on Sunday, bringing the cold air in everywhere (more on that later). But the surface is only part of the equation. Warmer air will also move in aloft. How far inland it moves is something that that models disagree on right now. With warm air aloft and cold air at the surface, the precipitation will change to sleet or freezing rain, depending on how thick the layer of warm air is above the surface. Obviously, this will have a significant impact on snowfall amounts. Everything should go back to all snow Sunday afternoon as the coastal front collapses toward the coastline.

The high-resolution NAM model shows a well-defined coastal front setting up in the Merrimack Valley and the I-495 belt Sunday morning. Image provided by WeatherBell.

We’ve got more concerns than just what falls from the sky though. The full moon is Sunday night, which means that tides will be astronomically high. That is usually enough for some minor coastal flooding in a few spots. However, when you add in east to northeast winds of 15-25 mph and gusts to 40-50 mph (or more), then you get coastal flooding in a much wider area, possibly even some moderate flooding in the more vulnerable locations. This is mainly a concern for the high tide that occurs Sunday morning. The winds will also be a concern inland, as it will create blowing and drifting snow, making driving even more hazardous.

We mentioned earlier that the coastal front would collapse to the coastline during the afternoon, bringing cold air back in everywhere. As that cold air comes rushing in, we expect everything to quickly freeze up Sunday afternoon and evening. This will create black ice on the roads, but more importantly, any snow still on your driveway, cars, roads, etc, will quickly turn into cement. You’ll want to get outside and quickly clear everything off, because the longer you wait, the more difficult it will become. Temperatures will continue to drop Sunday night, and as high pressure builds in, skies will clear out, which may allow for viewing of the total lunar eclipse Sunday night. On Monday, temperatures won’t rise that much, with many places likely staying in the single numbers or lower teens. It will still be breezy, so wind chills may stay below zero all day long. Temperatures will start to moderate on Tuesday, but longer-range indications are that we are in a colder (and stormier) pattern now, so winter has finally arrived.

This is the forecast high temperatures for Monday based on the GFS model. It’s going to be cold. Image provided by Weathermodels.com

OK, finally, the part you’ve all been wondering – how much are we getting? As we’ve said, the amount of sleet and freezing rain will have a significant impact on snow accumulations, so we’re going to keep our ranges somewhat wide for now, and if need be, we’ll put out an update on Saturday.

Cape Cod: 2-4″
Southeastern Massachusetts/Southern Rhode Island: 3-6″
I-95 corridor (including Boston and Providence): 4-8″
MetroWest/North Shore: 6-12″
Merrimack Valley/NH Seacoast: 8-14″
Southern NH/Southern ME (Nashua/Manchester/Portland): 10-16″
Central NH (Concord): 12-18″

The NAM model is probably closest to our thinking right now, though some of these numbers may be a bit higher than our thoughts. Image provided by the College of DuPage.

If time allows, and/or there is a significant change in the forecast, we’ll update this on Saturday.

Weekly Outlook: January 14-20, 2019

The hype train is already leaving the station – that’s right, there’s a “chance” for some snow next weekend. Since we haven’t had much snow yet this winter (haven’t heard many complaints about that), much of the media is going nuts, salivating at the prospect of a week of trying to outdo each other in the stupidity department. You’ll find none of that here, so let’s just get to the forecast.

We really haven’t that much snowfall so far this winter. Will that change? We’ll see. Image provided by Weathermodels.com

We will start the week off with a little bit of snow for some of you, mainly along the coast and south of Boston. Northeast winds blowing over the still relatively mild Atlantic will produce a little ocean-effect snow across Cape Cod and parts of Plymouth County. We’re not talking about much more than a dusting, though a few localized spots could see an inch or even two. Otherwise, high pressure keeps us dry and seasonably cold right through Thursday.

On Friday, low pressure will approach from the west. We’ll see some light snow or rain with this system, with the best chance for any snow mainly north of the Mass Pike. Obviously, this will depend on exact track of the system, but temperatures won’t be that cold, the system won’t be that strong, and it’ll be moving along fairly quickly. So, not that big of a deal. High pressure builds in late Friday into Saturday while another storm system moves into the Southeast. This brings us to Sunday.

A little bit of snow is expected on Friday, mainly north and west of Boston. Image provided by Pivotal Weather.

Many of the forecast models are showing the potential for this system to head up the East Coast Saturday night into Sunday while high pressure moves into Quebec. This is the setup for a classic Nor’easter, and most of the models are showing this. They mainly show that Sunday will feature heavy snow, strong winds, and likely some coastal flooding due to the astronomical high tides. Some of the models are showing snowfall amounts in feet, not inches. Of course, many in the media have seen this, and are gleefully hyping it up already, while throwing in words like “possible” as an afterthought, after showing maps with model snowfall amounts, meaning that nobody hears the word “possible”. Here’s the thing, this is still 6-7 days away, and as we’ve mentioned more than a few times, the models have been absolutely horrible beyond about 2-3 days. So, why would we suddenly take a 7-day forecast and believe it now? Remember, the storm that hit Washington, DC yesterday was forecast by the models a week ago to bury New England instead. In short, yes, there is a “chance” for a storm next weekend, but we’re not buying what the models are selling just yet. If they are still forecasting this as we get towards Thursday or Friday, then maybe we’ll jump on board and have a blog post about it. Until then? Nope, not gonna do it.

One thing we are certain about for next Sunday is that the Patriots season will continue, with a trip to the Super Bowl on the line against the Kansas City Chiefs. Right now, it looks like we’ll have clear skies for the game which kicks off at 6:40pm EST on Sunday, with a game-time temperature around 10 degrees. Obviously, this is subject to change for the reasons we outlined above in reference to the models. As for the game itself, the Patriots will make a 3rd straight trip to the Super Bowl after they knock off the Chefs Chiefs by a score of 34-31.

Monday: Morning flurries along the coast south of Boston, otherwise becoming partly to mostly sunny. High 27-34.

Monday night: Clear to partly cloudy. Low 15-22.

Tuesday: Sunshine and a few clouds. High 30-37.

Tuesday night: Clear to partly cloudy. Low 18-25.

Wednesday: Partly sunny. High 34-41.

Thursday: Sunshine gives way to increasing clouds. High 23-30.

Friday: Cloudy with a chance for snow north of the Mass Pike, rain or snow south of the Pike. High 33-40.

Saturday: Some early sun, otherwise partly to mostly cloudy. High 24-31.

Sunday: Cloudy and windy with a chance of snow. Highs ranging from the teens north and west of Boston, to the lower 30s across southeastern Massachusetts.

Weekly Outlook: January 7-13, 2019

Since we’re into January, how about we change things up and get some snow in here? Whaddyathink? Good idea? Bad idea? Don’t worry, we’re not looking at much, well at least not in in the next few days.

The week starts off on a sunny, but chilly note with high pressure in control. Both the sunshine and cold temperatures won’t last long though as low pressure starts to approach the region. Clouds move in late in the day with some light snow developing at night. However, milder air will move in, so we’ll see a fairly quick change to rain south of the Mass Pike, with the change taking place farther north during the morning. Everything winds down by early afternoon, with accumulations of an inch or two possible, mainly in southern New Hampshire.

The Bears got a double-doink on Sunday, we get a double-whammy Tuesday into Wednesday, but ours won’t be that tough to take. Loop provided by Tropical Tidbits.

The story doesn’t end there, as another system will quickly follow for Tuesday night and Wednesday. This one will start off as rain everywhere Tuesday night, but as the system moves into the Gulf of Maine, it will bring some cold air in, possibly changing the rain back to snow before ending Wednesday afternoon or evening. Again, we’re not looking at much accumulation, so this is not a big deal. High pressure builds in with much colder weather behind that system for Thursday through Saturday. When we say cold, we mean COLD. As in, the type of weather we haven’t had since Thanksgiving. This brings us to next Sunday.

Highs in the upper teens to middle 20s on Friday? You’d think it was January or something. Image provided by Weathermodels.com

Before we get to our thoughts on Sunday, let us say that most of the forecast models have been utter crap (note: technical term) this winter beyond about 2-3 days. This seems to happen every winter, but it doesn’t stop some of the morons that don’t know better from posting maps for a “potential” snowstorm that is a week or more away. As you’ve probably figured out by now, one of those “potential” storms is being shown by at least one of the models for the timeframe of next Sunday/Monday. In fact, over the past 2-3 days, nearly all of the models have shown this storm in one form or another, but never all at the same time. Some of them show the storm staying well south of us, with nothing happening. Some show it cutting right across New England, with rain to the south and snow to the north. Some show it clipping us with snow along the coast and nothing inland. Some show it not developing at all. And finally, some show a crippling blizzard. Of course, it’s the last one that gets the attention of the amateurs, because that’s the best way to generate clicks on their websites. It’s also the least likely scenario.

Of course, Sunday is also an important day because the Patriots host the Chargers at Gillette Stadium that afternoon. The Patriots excel in cold weather and snow, so this wouldn’t be a bad thing, unless you have tickets. The Patriots are 45-10 when the game-time temperature is 34 or colder, 13-2 in the postseason. They are 11-0 in Foxboro, when it snows.

As for the forecast for Sunday? We wouldn’t be surprised if there was some snow, but probably not during the game. Obviously we’ll keep an eye on things, and if it does look like a storm is headed our way, we’ll have a special blog post once things become clearer. As for the game itself – Patriots 27 Chargers 23, and a trip to the AFC Championship game for the 8th year in a row.

Weekly Outlook: December 31, 2018-January 6, 2019

Remember last week when we hinted that First Night could be really cold? Well, it seems as though we were wr….wro….wro….we were a little off.

First Night is actually going to be bitterly cold, if you’re planning on spending it in Fargo, where wind chills will be 25 to 35 degrees below zero when the clock strikes midnight. Around here? It’ll be a tad milder. Low pressure will move from the Great Lakes into northern New England later today and tonight. Precipitation will move in this evening, and it will likely still be cold enough for some snow, sleet, or freezing rain from the Merrimack Valley northward, at least at the start. Elsewhere, just some rain is expected. Milder air will move in aloft, and eventually at the surface too, changing the precipitation to rain everywhere overnight. That warm air may take its time moving in, especially from the Merrimack Valley into southern New Hampshire, but New Years Morning will likely be quite mild across much of the area. Don’t get used to it, as a cold front moves through during the morning, with windy and colder conditions likely for the afternoon.

Tuesday afternoon is also when the Winter Classic takes places, featuring two of the absolute best sweaters in the NHL (and two of our favorite teams here at StormHQ) – the Boston Bruins and the Chicago Blackhawks. We’ll refrain from comment about the fact that it’s taking place at the home of the Angry Leprechauns – Notre Lame, er, Dame, or that outdoor hockey games are much better on TV than in person (trust us, we’ve experienced it), but for the game itself, it should be cloudy with temperatures in the middle 30s, which is pretty much perfect for outdoor hockey.

We’re not fans of outdoor hockey games, but we are fans of the Bruins and the Blackhawks. The weather will cooperate, so let’s hope for a great game (and a Bruins victory). Image provided by the National Hockey League.

As we head deeper into 2019, things get quieter (and colder) around here for a few days. High pressure builds in, and we’ll have generally dry and cool conditions for much of the remainder of the week, as we remain in a split jet-stream pattern. Basically, we’ve got a northern stream keeping some storms across southern Canada and to our north, and a southern stream keeping the warmer, juicier storms to our south. This will be the case on Friday when it looks like a southern stream storm will come along and give us some rain, while the northern stream remains locked up in Canada. If you don’t like snowstorms, then you want this pattern to continue. Why? Because if the streams cross, to quote Dr. Egon Spengler, “It would be bad.” That’s usually how we end up with some of our bigger snowstorms in the winter. As the storm moves by, colder air will work in behind it, with the rain possibly changing over to snow before ending on Saturday. High pressure then returns for next Sunday.

New Years Eve: Becoming mostly cloudy. High 37-44.

Monday Night: Cloudy and becoming breezy with rain developing, starting as some snow or a wintry mix from the Merrimack Valley into southern New Hampshire. Rain ends towards daybreak. Low 32-39 during the evening, then temperatures will hold steady or slowly rise overnight.

New Years Day: A lingering shower early, then becoming partly to mostly sunny, windy, and colder. High 49-56 in the morning then temperatures quickly drop through the 40s during the afternoon.

Tuesday night: Clear to partly cloudy. Low 18-25.

Wednesday: Mostly sunny. High 27-34.

Thursday: Partly sunny, slight chance for a snow or rain shower. High 35-42.

Friday: Cloudy with rain developing in the afternoon, continuing at night. High 38-45.

Saturday: Cloudy and breezy with rain, possibly mixing with or changing to snow before ending late in the day. High 34-41.

Sunday: A mix of sun and clouds, breezy. High 36-43.
