Weekly Outlook: March 23-29, 2020

We’ve finally made it to Spring, so naturally, we’re expecting some snow. Look on the bright side – for many of you, it won’t have any impact on your commute!

Clouds will stream into the region this morning as low pressure starts to take shape off the Mid-Atlantic coastline. This system will strengthen as it heads northeastward, passing south and east of Nantucket early Tuesday. Ahead of it, we could see some flurries or snow showers develop late this morning thanks to an onshore flow, but the steadier precipitation associated with the storm arrives during the mid-to-late afternoon hours. There will be some dry air in place, so as the atmosphere moistens up, it will allow temperatures to drop, so we’ll see the precipitation start off as snow for most, with rain across southeastern Massachusetts and Rhode Island. Temperatures will likely be near or above freezing, so a quick change to rain is expected across much of eastern Massachusetts. The changeover should take place during the evening across the Merrimack Valley and New Hampshire Seacoast, and by midnight across the rest of southern New Hampshire. This will be a fast-moving storm, so everything should wind down before midnight. Even this close to the storm, we’ve got some significant discrepancies among the models as the how much snow to expect. There are still some models forecasting significant accumulations for parts of the area, and then there’s others like the GFS, playing the part of Alfred E. Neuman.

This pretty much sums up the GFS forecast for today’s storm.

As for how much we’re expecting, we’ll get to that in a second. There are some facts both good and bad that go into that forecast, that we’d like to explain.
1. Temperatures will be right around freezing in many places, so what does fall as snow will be wet snow.
2. Elevation will play a role in amounts, as higher elevations should receive more snow, as they’ll be a bit colder.
3. Ground temperatures, especially pavement temperatures, are getting fairly mild now, so accumulations will be more likely on grassy surfaces.
4. The initial burst of snow will fall during the daytime. With the higher sun angle, that’ll make it a little tougher to accumulate as well. However, once it gets dark out, that isn’t a factor.
5. The closer you are to the ocean, the quicker precipitation will change to rain.

So, having said all that, here’s our forecast:
Southeastern Massachusetts/Southern Rhode Island – Zip, Zero, Nada
I-95 Belt (Boston-Providence) – A few flakes
Metro West/North Shore/Northern Rhode Island – An inch or so
Merrimack Valley/New Hampshire Seacoast – 1-2 inches
Southern New Hampshire (Nashua/Manchester/Concord) – 1-3 inches, maybe 4″ in a few spots

The jackpot will be from the Worcester Hills into the Monadnocks, where some places could see as much as 4-8 inches.

While not identical to our forecast, the National Weather Service model blend forecast is similar to ours. Image provided by Weathermodels.com

So, the storm pulls away and skies clear out on Tuesday. With sunshine, temperatures should get well into the 40s, maybe even some low 50s. So, you probably won’t even need to shovel, not that you really can go anywhere. The nice weather doesn’t last long as another system quickly follows for later Wednesday into early Thursday. This system will likely take a similar track to today’s storm, but the atmosphere will be a bit warmer, so this should be mainly rain, with some wet snow at the start across southern New Hampshire and possibly the Merrimack Valley.

High pressure builds back for Thursday into early Friday with drier conditions. We may be looking at yet another storm bringing in some rain on Saturday before drier weather returns on Sunday

We didn’t have a St. Patrick’s Day parade, so how about a parade of low pressure systems this week? Loop provided by Pivotal Weather.

Monday: Cloudy with snow developing in the afternoon, except rain across southeastern Massachusetts and southern Rhode Island. High 3542.

Monday night: Cloudy and breezy with snow changing to rain from southeast to northwest before ending. Low 31-38.

Tuesday: Becoming partly to mostly sunny. High 47-54.

Tuesday night: Clear during the evening, clouds move back in overnight. Low 30-37.

Wednesday: Cloudy and breezy with rain likely late in the day and at night, possibly mixed with some wet snow, mainly across southern New Hampshire and the Merrimack Valley. High 40-47.

Thursday: Mostly cloudy with showers ending early, some sun may develop in the afternoon. High 43-50.

Friday: A sunny start, then clouds return, breezy. High 49-56.

Sunday: A mix of sun and clouds, breezy. High 51-58.

Weekly Outlook: March 16-22, 2020

While everything around comes to a grinding halt, the weather does not, which means that here at StormHQ, The Show Must Go On. This week, that will be a variety show.

We start the week off with high pressure in control, so we’ll have a sunny but rather chilly Monday. The dry weather won’t last much longer though, as the high moves offshore and a disturbance moves into the Great Lakes. This will bring some precipitation in for Tuesday. While most of us will just see some rain, there could be some wet snow mixed in at that start Tuesday morning across southern New Hampshire. We’re not expecting any accumulation, and despite what this winter has been like, this is a fairly normal occurrence in mid-March. The rain ends late in the day and high pressure builds back in with sunshine and seasonable conditions returning for Wednesday.

While today is on the chilly side, the first 2 weeks of March are among the Top 5 warmest on record for the region. Image provided by the Southeast Regional Climate Center.

The latter half of the week isn’t looking that great right now. We’re not expecting any big storms, but a series of smaller ones. The first one moves in for Wednesday night and Thursday. With some cold air in place, this one may start as snow for much of the area (except southern areas), but should change over to rain during the morning. If there’s any accumulation (and it is a possibility this time), it will be most likely across grassy areas and at elevation. Would we be surprised if we end up with some coatings from southern New Hampshire into the northern and western suburbs of Boston? Of course not. In fact, one model shows the potential for a lot more than just coatings. if the trend continues that way, we’ll do a special update later in the week.

There’s still a wide variety of model solutions for Thursday morning, some some snow is possible. Images provided by Pivotal Weather.

The rain ends during the Thursday evening, but another storm quickly follows. This one will move across the Great Lakes, with significantly milder air expected on Friday. Of course, it will be accompanied by rain, but it’s not like you can do much to head out an enjoy it anyway, right? The rain ends Friday night as a cold front moves through, then high pressure builds in next weekend with sunshine and colder weather once again.

Friday could be a very mild day despite cloudcover and some showers. Image provided by WeatherBell.

Monday: Sunshine fades behind increasing and thickening afternoon clouds. High 34-41.

Monday night: Mostly cloudy. Low 26-33, but temperatures may hold steady or drift up a few degrees after midnight.

Tuesday: Cloudy with showers likely, possibly starting as some wet snow across southern New Hampshire. High 44-51.

Tuesday night: Becoming clear. Low 27-34.

Wednesday: Sunshine gives way to afternoon clouds again, snow develops late at night, except rain along the South Coast. High 43-50.

Thursday: Cloudy with snow changing to rain, ending by evening. Some accumulation is possible, mainly well north and west of Boston. High 43-50.

Friday: Cloudy, breezy, and quite mild with showers redeveloping. High 62-69.

Saturday: A cloudy start, then skies become mostly sunny, breezy. High 43-50.

Sunday: Partly to mostly sunny. High 36-43.

Weekly Outlook: March 9-15, 2020

March Madness is upon us, and we’re not just talking about the NCAA basketball tournament. We’ve got some interesting weather coming up this week.

High pressure slides offshore today, and with southwest winds flowing around that high, we’ve got some very mild weather on tap. Temperatures should get into the 60s in many locations today, with some spots possibly topping 70. Not everywhere will be that warm though. Along the South Coast, those southwest winds will be blowing over water that is still in the 40s, so it”ll be much cooler across the Cape, Islands, Southeastern Massachusetts and southern Rhode Island. A backdoor cold front may move into the New Hampshire Seacoast and possibly northeastern Massachusetts tonight, with much cooler conditions, but it will likely head back northward on Tuesday ahead of an approaching cold front. Most of the region should be quite mild once again despite some cloudcover. That front brings in some showers late Tuesday and Tuesday night.

Temperatures could top 70 degrees in spots this afternoon. Image provided by WeatherBell.

High pressure returns on Wednesday with some sunshine and cooler conditions. The dry weather doesn’t last too long as another weak system moves in Wednesday night. This one will produce some rain showers, but a few wet snowflakes are possible, especially across southern New Hampshire and the Merrimack Valley.

It’s been a very dry start to 2020, so we can use any rain that we can get. Image provided by the Northeast Regional Climate Center.

Dry weather returns on Thursday, but again, it looks like it will be a brief respite. Another system moves in for Friday with more rain. While it doesn’t look that heavy right now, it will be a bit more substantial that the system Wednesday night. High pressure builds in behind that system with dry and seasonably cool conditions next weekend.

Monday: Sunshine filtered through some high clouds at times. High 62-69, cooler across the South Coast and Cape Cod.

Monday night: Becoming partly to mostly cloudy. Low 41-48, except 34-41 from Essex County up into the New Hampshire Seacoast and Southern Maine.

Tuesday: Plenty of clouds, breezy, some showers may develop late in the day. High 57-64, cooler across the South Coast and Cape Cod.

Tuesday night: Mostly cloudy and breezy with showers likely during the evening, some clearing is possible late at night. Low 36-43.

Wednesday: Becoming mostly sunny in the morning, clouds return in the afternoon, chance for a few showers at night, maybe a few wet snowflakes mixed in as well. High 48-55.

Thursday: More clouds than sunshine. High 45-52.

Friday: Partly to mostly cloudy, breezy, and mild again with some rain likely. High 50-57.

Saturday: Mostly sunny and breezy. High 44-51.

Sunday: Partly sunny. High 39-46.

Weekly Outlook: March 2-8, 2020

We’re into March which means that Spring has arrived (meteorological spring). It’ll even feel like Spring for a good portion of the week too.

On average, high temperatures should be in the upper 30s to lower 40s during the first week of March. Image provided by Weathermodels.com

We start the week off with a fantastic day, probably the pick of the week. High pressure slides offshore and a warm front moves through, so we’ll have sunshine after some morning clouds and temperatures possibly getting into the 50s in many areas. A cold front spreads clouds back in late in the day, with some showers possible at night.

Tuesday looks to be another mild day with temperatures well into the 50s, maybe even 60 in spots. A weak system will approach the region during the day, so we’ll have plenty of clouds and some sunny breaks, but some rain is expected to move in during the evening and at night. The rain shouldn’t be that heavy, and it should end by daybreak. Behind the system, breezy and somewhat cooler conditions settle in for Wednesday as high pressure starts to build in, but temperatures should remain above normal. Thursday remains dry and mild with high pressure in control.

Temperatures could get close to 60 again on Tuesday in many locations. Image provided by WeatherBell.

Friday is where things start to get interesting. Low pressure will be moving across the Great Lakes while a second low pressure area moves off the Southeast coastline. One or both of these systems could impact us, but that’s where the uncertainty lies. You may hear some of the TV meteorologists talking about the systems “phasing”. What that means is when you get the two branches of the jet stream (northern and southern) to join together or “phase”. When this happens, you usually get the disturbances moving through each jet stream to join together and create a big storm system. When that occurs with cold air in place, we get big snowstorms. When they don’t phase, we just get your average run-of-the-mill storm system moving through. That’s what we’re looking for with the potential on Friday/Saturday. Some of the models have been hinting at this possibility, but some don’t show the phasing until well offshore, which is great for snow-lovers in Nova Scotia, but not most of New England. Given how this winter has gone, we’re leaning away from the idea of a snowstorm, but it’s obviously possible. At the very least, we’ll likely have some snow or rain from the northern system as it moves through. We’ll keep an eye on this for the next few days, and if necessary, have a special blog later in the week.

High pressure builds in behind the system with colder and drier conditions, but they’ll likely be short-lived, with another warmup to start next week.

Monday: Morning clouds, then becoming partly to mostly sunny and breezy. High 45-52.

Monday night: Clouds return along with a few showers. Low 36-43.

Tuesday: Intervals of clouds and sunshine, showers develop late in the day. High 52-59.

Tuesday night: Cloudy and breezy with some light rain likely. Low 36-43.

Wednesday: Becoming partly sunny and breezy. High 46-53.

Thursday: Sunshine and lots of it. High 44-51.

Friday: Cloudy with rain or snow possible late in the day and at night. High 41-48.

Saturday: Rain or snow ending in the morning, some late-day sunshine is possible, breezy. High 32-39.

Sunday: Partly to mostly sunny. High 41-48.

Weekly Outlook: February 24-March 1, 2020

As we approach the end of February, there’s something you’ll need this week, and it’s not a shovel – it’s an umbrella.

We actually start the week off with another dry and mild day thanks to high pressure, but you’d better enjoy it, because things go downhill for the rest of the week. Temperatures should get into the 50s again, possibly even topping 60 in spots, but along the coast, we may have a seabreeze develop in the afternoon (yes, you read that right). A weak cold front moves through at night, bringing temperatures back toward normal, but that sets the stage for the next few days.

Temperatures should get well into the 50s across much of the area this afternoon. Image provided by Weathermodels.com

That front will likely stall out south of New England and stay there on Tuesday. A weak wave of low pressure will ride along the front, bringing some showers to the region. They won’t be that heavy, and won’t be that widespread, so the day won’t be a washout. Across southern New Hampshire and the Merrimack Valley, we may have some cold air linger long enough that we get a little bit of freezing drizzle or maybe even a few wet snowflakes. Drizzle and fog linger for Tuesday night into Wednesday morning before the next storm system arrives.

Precipitation has been well below normal since Christmas, so we need some rain. Image provided by the Northeast Regional Climate Center.

Later Wednesday into Thursday, low pressure will move into the Great Lakes while a secondary area of low pressure develops near or just off the Mid-Atlantic coastline. This secondary low will spread some rain in for Wednesday afternoon and night, and some of it could be heavy. Once again, we may have some cold air in place across the Merrimack Valley, which could lead to a wintry mix or even some snow, but this is far from definite at this point. We’ll keep an eye on this over the next few days.

Depending on where you are and which model you believe, Thursday morning could be wet, white, or already drying out across the region. Images provided by Pivotal Weather.

That low in the Great Lakes swings a cold front through Thursday morning, bringing an end to the precipitation, and ushering cooler and drier air back into the region. High pressure then builds in with cold and dry conditions as we head into the end of the week and the weekend. The only exception could be across parts of Cape Cod and the Islands, where some ocean-effect snow is possible as colder air blows in over the relatively mild ocean.

Monday: Plenty of sunshine with a few afternoon clouds. High 53-60.

Monday night: Becoming mostly cloudy. Low 31-38.

Tuesday: Plenty of clouds with some showers likely. High 44-51.

Tuesday night: Cloudy, with periods of drizzle and fog likely. Low 32-39.

Wednesday: Clouds, drizzle and fog linger, becoming breezy at night with steadier rain moving in, possibly mixed with snow from the Merrimack Valley into Southern New Hampshire. High 39-46.

Thursday: Cloudy with showers ending in the morning, some afternoon sunny breaks may develop, breezy. High 43-50.

Friday: Partly sunny and breezy. High 31-38.

Saturday: A mix of sun and clouds, breezy. High 28-35.

Sunday: Mostly sunny. High 25-32.

Weekly Outlook: February 17-23, 2020

The active pattern we’ve been in a for a few weeks has left, and now we’re in a much less active one, and it will actually feel like February.

A weak cold front crosses the region this morning, but you’ll barely notice it. We’ll still have sunshine and mild temperatures. That won’t last long though, as low pressure will move from the Great Lakes today into the St. Lawrence Valley on Tuesday. This will result in some rain around here on Tuesday. However, it will still be on the chilly side when the precipitation moves in by early afternoon (it is February after all), so we’ll likely see some snow to start, mainly from the Merrimack Valley into southern New Hampshire. We’re not expecting much accumulation, mainly an inch or so, maybe 2 inches in parts of central New Hampshire, before a change to rain occurs during the afternoon. The rain ends during the evening, as the storm pulls away, then skies start to clear out late at night.

This is not going to be a big snowstorm, and the rain will wash away a lot of it during the afternoon and evening. Image provided by WeatherBell.

After that, the forecast for the rest of the week is very easy. High pressure builds in for Wednesday with sunshine and cooler conditions. Thursday and Friday will be even colder with sunshine, then temperatures start to moderate over the weekend with conditions remaining dry.

High pressure slowly moves from the Northern Plains on Wednesday to the Mid-Atlantic states by Sunday, keeping us dry for several days. Loop provided by Pivotal Weather.

Monday: Partly to mostly sunny. High 36-43.

Monday night: Clear skies during the evening, then clouds move in overnight. Low 19-26.

Tuesday: Snow and rain developing around midday, changing to all rain, during the afternoon. High 34-41 north of the Mass Pike, 42-49 south of the Pike.

Tuesday night: Rain ending by midnight, then skies start to clear out late at night. Low 28-35.

Wednesday: Becoming partly to mostly sunny and breezy. High 35-42.

Thursday: Sunshine and a few clouds, breezy, and turning colder. High 23-30.

Friday: Sunny and cold. High 25-32.

Saturday: A mix of sun and clouds, milder. High 38-45.

Sunday: Partly to mostly sunny. High 42-49.

Weekly Outlook: February 10-16, 2020

Our weather pattern will remain fairly active this week, but it will be more wet than white. Winter’s not over though, and Mother Nature will have a reminder of that late in the week.

So far, this winter has been classified as mild using data from Blue Hill. For more info on the Accumulated Winter Season Severity Index, visit https://mrcc.illinois.edu/research/awssi/indexAwssi.jsp (Image provided by the Midwest Regional Climate Center)

We start the week off with some rain showers this morning, and a few wet snow flakes across southern New Hampshire. This rain won’t be too heavy and won’t last too long, as a cold front will drop southward by early afternoon, bringing the precipitation to an end. We may even see some clearing late in the day, especially north of the Mass Pike, as high pressure tries to build in to the north. This is somewhat important, as it will bring some colder air into the region. Why is it important? That cold front will lift back northward as a warm front late Monday night into Tuesday. With that colder air in place, we may see some snow or sleet develop before daybreak, mainly away from the coast, before the warmer air moves back in Tuesday morning, changing everything back to rain, ending late in the day. This time the rain will be a little heavier as the associated low pressure system will be a bit stronger, but overall, we’re still not looking at a big storm.

Between now and Tuesday evening, most of the region will receive around half an inch of rain or less. Image provided by WeatherBell.

High pressure builds in for Wednesday with drier air, but it won’t last too long. We’ll still have a mild day (by February standards), but it’ll be a tad cooler than Monday or Tuesday. The next system moves in for Wednesday night and Thursday. Again, we’ll have some cold air in place to start, which likely means the precipitation starts as snow again. This time, we may even see some accumulations Thursday morning before a change to rain takes place. Again, we’re not expecting a big storm, but a few inches of snow could result in a messy Thursday morning commute, especially north and west of Boston.

High pressure builds in for Friday and Saturday with some much colder weather. Temperatures will actually be below normal, which hasn’t been a common occurrence this winter. As the high slides offshore, temperatures will moderate before yet another storm moves in, with some rain likely late Sunday and Sunday night.

Saturday morning could be quite chilly across the area. Image provided by Weathermodels.com

Monday: Cloudy and breezy at times with showers ending from north to south during the afternoon. Some sunny breaks may develop in the afternoon, mainly north of the Mass Pike. High 38-45.

Monday night: Partly to mostly cloudy with showers redeveloping south of the Mass Pike, possibly starting as snow or a wintry mix across the interior. Low 28-35.

Tuesday: Cloudy with showers likely, ending late in the day. High 37-44.

Tuesday night: Becoming partly cloudy. Low 25-32.

Wednesday: Sunshine filtered through some afternoon high clouds. Cloudy at night with snow developing, changing to a wintry mix and then rain south of the Mass Pike by daybreak. High 36-43.

Thursday: Mostly cloudy with snow changing to a wintry mix and then rain during the morning from south to north, ending late in the day. High 38-45.

Friday: Sunshine and a few clouds, breezy, and much colder, slight chance for some snow showers across the Outer Cape. High 23-30.

Saturday: Sunshine fades behind increasing afternoon clouds. High 24-31.

Sunday: Cloudy and breezy with rain developing in the afternoon. High 36-43.

Weekly Outlook: February 3-9, 2020

Yesterday was Groundhog Day and also the end of football season, but today brings us a sign that Winter will be over soon and Spring is right around the corner. It’s Truck Day! The Red Sox equipment truck leaves Fenway today to begin the drive down the coast on I-95, eventually heading over to I-75 to arrive in Fort Myers, Florida later this week. Pitchers and catchers report to Spring Training a week from tomorrow. As for the weather, we’ve got a Spring preview today, but the rest of the week won’t be as pleasant.

Sick of winter? Today is Red Sox Truck Day! Spring training isn’t far behind. Image provided by Boston Herald.

A warm front will cross the region this morning, with high pressure briefly building in behind it. There could be a little patchy fog this morning, but sunshine should develop, with high temperatures getting into the 40s, maybe even topping 50 in some spots. Unfortunately, today is the pick of the week. A storm system will approach on Tuesday, with some showers likely. As colder air settles in behind the system, a change to wet snow is possible Tuesday night and Wednesday morning before the precipitation ends. There might be enough to coat the ground in some spots, but that’s about it.

Temperatures should get well into the 40s across the region this afternoon. Image provided by WeatherBell.

As our storm pulls away, another one quickly follows as the pattern starts to get more active. Precipitation ahead of this system moves in Wednesday night and with colder air in place it will likely start as snow. Some accumulations are likely, but they should be mostly light to moderate the farther north you go, with a change to sleet and then rain from south to north Thursday morning. It’s a little too early for specifics, but if this threat continues, we’ll have a special blog post before the storm with amounts. The Thursday morning commute will likely be impacted by this storm.

We get a brief break Thursday afternoon, then another storm heads our way for Thursday night and Friday. Right now, this one looks like mostly rain, and probably quite a bit of rain, but that is not etched in stone just yet. While we’re expecting it to be quite mild with the storm passing near or just north of the region, thus putting most of the region in the warm sector, there is still some uncertainty in exactly where the storm tracks. The farther south and east it tracks, the better the chance cooler temperatures and for some snow across the interior, especially well north and west of Boston.

There is quite a bit of disagreement among the models as to temperatures around here on Friday. Images provided by Pivotal Weather,

Our active pattern looks to continue into the weekend, as another system moves through, with some snow possible Sunday. There’s plenty of uncertainty on this one as well, so stay tuned.

Monday: Some patchy fog early, then becoming partly sunny. High 41-48.

Monday night: Increasing clouds. Low 26-33.

Tuesday: Mostly cloudy, chance for a few showers. High 38-45.

Tuesday night: Mostly cloudy with showers possibly changing to snow showers, mainly north and west of Boston. Low 29-36.

Wednesday: Snow or rain showers end in the morning, some sunny breaks may develop in the afternoon. Snow redevelops late at night. High 35-42.

Thursday: Cloudy with snow in the morning, changing to over to sleet and freezing rain, then all rain during the afternoon. Rain may be heavy at night. High 35-42.

Friday: Cloudy and breezy with rain tapering off to showers during the afternoon, ending in the evening. High 44-51, except 36-43 from southern Maine and the NH Seacoast across to central NH.

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

Sunday: Cloudy with a chance of snow. High 33-40.

Weekly Outlook: January 27-February 2, 2020

This week’s outlook is a lot like last week’s. Dry weather during the week thanks to a large area of high pressure, then questions for the weekend.

For Monday through Friday, we’ve got a large area of high pressure in control. We’ll still have plenty of clouds around on Monday as an upper-level low pressure system moves across the Northeast. Clouds may linger into Tuesday, and with a northerly flow, we could even see some ocean-effect snow showers across the Outer Cape late Tuesday and Tuesday night. Not much accumulation is expected, but a few spots on the Outer Cape could see an inch or so. Wednesday through Friday will feature partly to mostly sunny skies, with chilly temperatures for Wednesday and Thursday, and some moderation on Friday.

Some ocean-effect snow is expected across the Outer Cape Tuesday night. Image provided by WeatherBell.

That brings us to next weekend. Once again, many of the models are showing the potential for a storm to impact the region. Some of the models even have it as a powerful storm. Once again, they aren’t anywhere close to agreement on the track of this system though. Some have a storm so far offshore that it will have little to no impact on us. Some have it so close that we get moderate to heavy snow inland with rain across southeastern New England. Others have it just far enough offshore to impact only areas south of Boston. On top of that, many of these models haven’t been consistent from one run to the next.So, once again, we’ll just wait and see what develops. If it looks like it could be a threat, we’ll have a special blog post later in the week.

The various members of the ECMWF Ensemble show that wide variety in forecasts for the potential storm system off the East Coast next weekend. Image provided by Weathermodels.com

Monday: More clouds than sunshine. High 38-45.

Monday night: Partly cloudy. Low 25-32.

Tuesday: Partly sunny, except mostly cloudy across Cape Cod with some late-day snow showers possible. High 34-41.

Tuesday night: Partly to mostly cloudy, some snow showers are possible across Cape Cod. Low 18-25.

Wednesday: Becoming partly to mostly sunny. High 31-38.

Thursday: Plenty of sunshine. High 30-37.

Friday: Partly to mostly sunny. High 36-43.

Saturday: Cloudy with a chance of snow or rain. High 36-43.

Sunday: Cloudy with a chance of snow or rain. High 37-44.

Weekly Outlook: January 20-26, 2020

We’ve actually got a quiet week coming up. The weekend might not be quiet, but we don’t have much to worry about before then.

The week is starting off on a chilly note with wind chills near or below zero this morning. Image provided by Weathermodels.com.

A large area of high pressure will build in and remain in control through Friday. That means we’ll have dry and chilly conditions through Wednesday, but as the high slides off to the east, temperatures will moderate for Thursday and Friday, likely to above normal levels for late January. That should allow the snow from Saturday’s storm to melt for the most part. The only exception to the dry forecast is across Cape Cod, especially the Outer Cape, where some ocean-effect snow showers are possible today and again on Tuesday.

Next weekend, things get complicated again. We’ll have a low pressure system moving towards the Great Lakes and a secondary area of low pressure developing near the Mid-Atlantic states. Some of the models show an upper-level low pressure area moving toward the East Coast at the same time, which would slow down or even stall out that developing surface low. The forecast will obviously depend on the development and track of that low, and at this point, it’s still 5-6 days away, so we’re not even going to attempt to nail down any details. We’ll just say that the potential is there for a long-duration storm that could produce snow or rain (or both). Obviously, the best chance for snow would be farther inland. Assuming this storm develops and looks like it will have a significant impact on the region, we’ll do a special blog post later in the week.

The European (ECMWF), Canadian (GDPS), and American (GFS) models all have different ideas about our potential storm’s location and impacts next Sunday morning. Image provided by Pivotal Weather,

Monday: Partly to mostly sunny, except plenty of clouds across Cape Cod with a few snow showers possible, mainly across the Outer Cape. High 21-28.

Monday night: Clear and cold. Low 8-15, possibly a little colder across southern New Hampshire and into the Merrimack Valley.

Tuesday: Partly sunny, chance for a few snow showers across Cape Cod, mainly the Outer Cape. High 22-29.

Tuesday night: Clear to partly cloudy. Low 10-17.

Wednesday: Plenty of sunshine, not as cold. High 30-37.

Thursday: Sunshine and a few clouds, milder. High 37-44.

Friday: Partly to mostly cloudy. High 38-45.

Saturday: Cloudy with a chance of snow or rain. High 34-41.

Sunday: Cloudy with a chance of snow or rain. High 36-43.
