Snow and cold temperatures are on the way, but neither will be around for too long.

Low pressure will develop off the Carolina coast tonight and head northeastward, passing well south and east of New England on Friday. It will spread some light snow into the region Friday afternoon and evening, mainly south of the Mass Pike, but possibly as far north as the MA/NH border. For much of the region, this will be “nuisance snow”, with a coating to an inch of accumulation. However, along the coast from Plymouth County to Cape Cod, things will be a bit different. Northeast to northerly winds off of the relatively mild Atlantic, will produce some ocean-effect snow. This is similar to the lake-effect snow you hear about near Buffalo, but not nearly as heavy. It will enhance to snow near the coast, with the potential for 2-4 inches in spots, maybe even a few heavier amounts. The storm pulls away Friday night, and some very chilly air settles in behind it. Temperatures may struggle to reach 20 in parts of the region on Saturday, with sub-zero wind chills, especially in the morning both Saturday and Sunday. High pressure moves off to the east for Sunday and Monday, allowing temperatures to begin to moderate. We will some clouds starting to move in again on Monday ahead of another storm system headed our way.
We’re not expecting much snow with this system, but along the coast you may need a shovel. Image provided by Weathermodels.com

Saturday night: Clearing, breezy. Low 9-16.
Sunday: Lots of sunshine, breezy. High 23-30.
Sunday night: Clear skies. Low 10-17.
Monday: Morning sunshine, increasing afternoon clouds, breezy. High 33-40.
It took until mid-January, but this week will finally feel like winter around here.
Temperatures will be well below normal this week. Image provided by WeatherBell.
The week starts off with high pressure providing the region with sunshine and chilly temperatures. Low pressure will start to organize across the Southeast and begin heading up the East Coast, spreading some clouds in during the afternoon and evening. While that system is heading our way, an upper-level disturbance will move toward the region from the Midwest. If these two systems were to come together, we could have quite the snowstorm on our hands…but that’s not going to happen. Instead, we’ll have the coastal low pass well south and east of New England while the upper-level disturbance moves through. The result will be a period of light snow developing toward midday Tuesday, ending before midnight. Most places will pick up 1-3 inches of snow, possibly a little more in spots, possibly a little less across parts of Cape Cod and the Islands where a little rain could mix in.
The models are in pretty good agreement that Tuesday’s storm will produce just a few inches of snow. Images provided by Pivotal Weather.
High pressure builds in behind the system with dry and chilly conditions for Wednesday and Thursday, though not nearly to the magnitude of what they have been experiencing from the Midwest into the Northern Rockies. Clouds start to stream in on Thursday as a scenario similar to Tuesday unfolds. Low pressure passes south and east of New England on Friday while an upper-level low moves in, resulting in another round of light snow. Much like Tuesday, it looks like just a few inches for most places, though we’re not expecting any rain across the Cape and Islands this time. As that system pulls away, Saturday is shaping up to be quite a chilly day with high pressure building in, likely the coldest one so far this winter, with some places struggling to reach 20 degrees in the afternoon. Sunday looks dry as well with high pressure still in control, but not as chilly as Saturday.
Wind chills will likely be below zero across most of the region Saturday morning. Image provided by Weathermodels.com
Monday: Sunny in the morning, clouds start to move in during the afternoon. High 27-34.
Monday night: Becoming cloudy. Low 18-25, temperatures may start to rise after midnight.
Tuesday: Cloudy with light snow likely. High 28-35, possibly warmer across Cape Cod.
Tuesday night: Clearing. Low 14-21.
Wednesday: Sunshine and a few clouds, colder. High 24-31.
Thursday: Increasing clouds, breezy. High 25-32.
Friday: Cloudy and breezy with light snow likely. High 26-33.
Saturday: Partly sunny, windy, and cold. High 17-24.
Another potent storm system is on the way, with quite a bit of rain and wind expected.
Most of the region can expect another inch or more of rain on Saturday. Image provided by Weathermodels.com
Before we get to the stormy weather, high pressure remains in control tonight and a good chunk of Friday with dry weather. Clouds will stream in on Friday as low pressure heads toward the Great Lakes once again. This storm will be fairly similar to the one we had a couple of days ago. However, the airmass in place ahead of it is not as cold, and the snowcover is mostly gone, so this one will be mainly rain for most of the region. There could be some light snow right at the start from central Massachusetts into southern New Hampshire, but it won’t last long. We’re also not expecting as much rain from this storm, though there will still be quite a bit, with widespread totals of 1-2 inches likely. This will worsen flooding issues across the region. Flood Watches have been issued for much of the area once again. Winds will also be gusty, but again, not quite to the magnitude of the last storm. Sustained winds of 20-30 mph are expected, with gusts upwards of 40 mph inland, and 50-60 mph along the coast. In addition, some coastal flooding is also possible at the time of high tide Saturday morning/early afternoon.
Wind gusts could exceed 50 mph along the coast again Saturday morning. Image provided by WeatherBell.
The rain should come to an end by midday Saturday, then we’ll start to clear out, with high pressure building in for Saturday night into Monday with windy and colder conditions. Even though it’s beyond the range of this outlook, we feel it’s worth mentioning that the models are showing the potential for another storm to impact the region on Tuesday, and this one could be more white than wet for much of the region. We’ll get into that in more detail in our Weekly Outlook early Monday morning.
Will another storm impact us on Tuesday? It’s a possibility. Images provided by Pivotal Weather.
Thursday night: Partly cloudy through the evening, clearing overnight. Low 27-34.
Friday: Sunny in the morning, clouds move back in during the afternoon. High 39-46.
Friday night: Cloudy and becoming windy with rain developing, possibly starting as some snow from central Massachusetts into southern New Hampshire. Rain could be heavy at times. Low 30-37 during the evening, temperatures rise overnight.
Saturday: Steady rain ending in the morning, a few showers possible through the afternoon with some late-day clearing, windy. High 51-58 in the morning, temperatures drop in the afternoon.
Saturday night: Clear to partly cloudy, windy. Low 25-32.
Sunday: A mix of sun and clouds, breezy, colder. High 32-39.
The first snowstorm of the season has pulled away, but we’re already looking ahead to two more potent storm systems later this week.
More snow than expected in the Merrimack Valley, otherwise, the storm behaved pretty much as expected. Image provided by the National Weather Service office in Norton, MA.
High pressure builds in today with dry and rather chilly conditions, thanks to the fresh snowcover. Tuesday starts off dry as well, but a strong storm system will head toward the Midwest, spreading clouds in. Temperatures will still be chilly, so when the precipitation moves in late in the day, it may start as snow or a wintry mix across the interior, with some accumulation possible. However, it won’t last too long. As the systems gets all wound up, strong southerly winds both at the surface and especially aloft will bring much warmer air into the region, changing everything to rain. Sustained winds of 15-25 mph with gusts of 40-50 mph are possible inland with the storm, but along the coast, we could be looking at sustained winds of 25-35 mph with gusts upwards of 50-60 mph or higher. This could lead to trees and power lines coming down with power outages a significant concern. Tides will be astronomically low, so the risk for coastal flooding is fairly low as well. The biggest problem aside from the winds will be heavy rain. Many areas could pick up 1-2 inches of rain or more. While this could lead to areas of flooding on its own, combine that with significant melting of the snow on the ground, and you’ve got a recipe for widespread flooding. We’ll see if that materializes over the next couple of days.
Strong southerly winds are expected across the region Tuesday night into Wednesday morning. Image provided by WeatherBell.
Rain ends early Wednesday, followed by windy and colder conditions during the day as the system moves across southeastern Canada. High pressure builds in for Thursday with diminishing winds. By Friday, another potent system moves into the Great Lakes, but things are a little more uncertain with this one. We could see a secondary low pressure system develop across the Mid-Atlantic states and head towards southern New England. If this does develop, then a colder scenario with at least some snow across the interior becomes more likely for Friday night into Saturday. If it doesn’t, then we’ll likely be looking at more rain, which could worsen flooding across the area. Another weak system could move through late Sunday with some snow showers possible.
Will there be a secondary low on Saturday or not? Time will tell. Images provided by Pivotal Weather.
Monday: Plenty of sunshine, breezy during the morning. High 32-39.
Monday night: Clear skies, a few clouds move in late at night. Low 12-19.
Tuesday: Becoming mostly cloudy with rain developing late in the day from Boston southward, snow north and west. Winds start to pick up late in the day. High 34-41.
Tuesday night: Cloudy and very windy with everything becoming all rain, heavy at times. Low 31-38 during the evening, temperatures rise overnight.
Wednesday: Cloudy and windy with rain ending in the morning, skies start to clear out during the afternoon. High 50-57 early, temperatures start dropping in the afternoon.
Thursday: Mostly sunny, breezy, colder. High 38-45.
Friday: Morning sunshine followed by increasing afternoon clouds, rain developing at night, possibly starting as snow well inland. High 39-46.
Saturday: Mostly cloudy and windy with rain ending in the morning, some clearing possible late in the day. High 50-57.
Sunday: Partly sunny, windy, colder, a few late-day snow showers possible. High 34-41.
We’re less than 24 hours away from the first snowstorm of the year for most of the region, and while not a blockbuster, it will still have a sizable impact on the region.

Low pressure will move across the Southeast and off the Mid-Atlantic coastline later today and tonight, passing south of New England on Sunday. Meanwhile, high pressure over Quebec will move into Atlantic Canada. While this high will provide cold air to start, due to its position and movement, combined with low pressure to the south, we’ve have gusty east winds across much of the region, possibly gusting to 30-40 mph or higher along the coast. With water temperatures still in the lower to middle 40s, this will mean that places close to the coastline will likely be rain or a mix to start. This includes parts of Cape Ann, the North Shore, Boston, and most of the South Shore, Cape Cod, and Southeastern Massachusetts. We’ll have a few flurries or sprinkles around this afternoon, but the steadier precipitation should move in between 6 and 9 pm. The precipitation may fall heavy at times overnight, but by daybreak winds will become more northeasterly, and eventually northerly towards midday. This will allow colder air to slide southward, changing the rain over to snow along the coast as well. This will also allow any untreated roads to rapidly ice up, so be careful if you will be out and about. The snow should eventually end during the evening, with winds rapidly diminishing overnight.

So, how much snow are we expecting? Well, if you read our initial forecast in the Weekend Outlook, we’re bumping numbers up a bit.
Cape Cod: Coating to 2 inches. Southeastern Massachusetts: 2-5″ I-95 corridor (Boston to Providence) and immediate North Shore: 4-7″ MetroWest/Merrimack Valley/Interior Essex County/Southern NH: 5-10″ isolated totals of 12″+
The Blend of Models is still closest to our forecast. Image provided by WeatherBell.
We’ll clear out for Monday with chilly temperatures, due to the fresh snowcover. Another system follows for late Tuesday and Wednesday, and while this one may have some snow to start, it will end up much warmer with strong winds and heavy rain being the main concerns.
Your luck has run out. Our first snowstorm of the winter is on the way this weekend.

High pressure builds in for tonight and Friday, with clearing skies, breezy, and colder conditions. Clouds star to move back in Friday night and Saturday as low pressure moves across the Deep South and into the Southeast. It’ll move up the coast on Saturday, likely passing south of the region on Sunday, while high pressure in southern Quebec slides off to the east. There is still some uncertainty as what exactly will transpire, so some of the next paragraph is subject to change.
There is still plnety of disagreement among the models as to the evolution of the low pressure system. Images provided by Pivotal Weather.
While the high over southern Quebec will provide us with plenty of cold air to start, it’s not in the perfect position to provide the region with enough cold air to keep everything all snow, especially near the coastline. Winds will be out of the east, allowing milder air to move in off of the relatively mild Atlantic. (To get mostly snow, you want to high to be a little farther west, so you get northeast winds across our area). There is also still some uncertainty as to exact track the low pressure area takes and how close it gets to the coastline, which will also lead to some rain in spots, especially near the coast. We should see the snow developing Saturday evening, likely starting as a mix or even just plain rain along the coast from Boston southward since winds will be out of the east. Snow will continue through the night, but it may stay rain or a mix right along the immediate coastline for a while. By mid-morning Sunday, as the low passes by, winds will shift from the east into the north, allowing the cold air to push back in, changing everything to all snow, even across Cape Cod and the Islands before everything winds down by evening. The rain and milder temperatures keep accumulations lower near the coast, but inland, this will not be a blockbuster storm, as the snow , while falling for a while, will only be light to occasionally moderate for most of the time. So, how much are we looking at?
Cape Cod: Coating – 2″ I-95 corridor (Boston-Providence and points South+East): 2-5″, lowest along the coast Areas North+ West of I-95: 4-8″ with isolated totals to 10″ possible.

Everything winds down Sunday night, and high pressure builds back in for Monday with sunshine and seasonably chilly conditions.
With fresh snowcover, Monday morning could be quite chilly across the region. Image provided by weathermodels.com
Thursday night: Clear skies, breezy. Low 17-24.
Friday: Plenty of sunshine, breezy during the morning. High 29-36.
Friday night: Partly cloudy. Low 20-27.
Saturday: Becoming mostly cloudy. High 32-39.
Saturday night: Snow developing, mixed with or changing to rain along the coast, becoming windy. Low 25-32 during the evening, temperatures hold steady or rise a bit overnight.
Sunday: Windy with snow likely, except rain or mix changing to snow along the coast by midday. High 32-39, temperatures rapidly drop along the coast in the afternoon.
Sunday night: Any lingering snow ends in the evening, some clearing late at night, winds rapidly diminish during the evening. Low 13-20.
New year, new weather pattern? Well, sort of. We’ll still have above normal temperatures to start, but things could be changing significantly by next weekend.

We start the week (and year) off with some clouds thanks to a weak system passing offshore, but we’ll start to clear out this afternoon. High pressure builds in for tonight and Tuesday with seasonably cool and dry conditions. Wednesday remains dry as well, but we’ll see clouds start to filter in by late in the day. As we head into Thursday is when things start to change. Low pressure passes offshore while a cold front moves in from the north and west. Neither system will be particularly potent, but they will both bring in some rain or snow showers- the offshore system to coastal areas, especially southeastern Massachusetts, and the cold front produces some scattered rain or snow showers across the region. High pressure builds in behind these systems with cooler conditions for Friday. Another front tries to drop down from the north on Saturday, but stalls out nearby with just some cloudcover accompanying it. This brings us to Sunday, and you may want to sit down for this part (if you’re not sitting already).

Low pressure moving out of the Tennessee Valley will redevelop near the Mid-Atlantic coastline, while high pressure builds into southeastern Canada. The developing low pressure system should pass south of New England while strengthening. Obviously, this is a week away, and we don’t want to get too detailed at this point, but things can and likely will change between now and then. but the potential exists for our first significant snowstorm of the winter on Sunday. There’s lots to iron out, such as where (if?) the rain/snow line will be? Will there be strong winds? How much of an impact will this storm have along the coast? Where will the heaviest snow fall (Or will there be any heavy snow?) There are too many questions, right now, and it’s just too early to answer them. However, consider this an early warning that there could be an impactful storm next Sunday. We’ll obviously have a much more detailed look at this potential storm in our Weekend Outlook on Thursday.
The models all show the potential for a storm on Sunday, but the details are still very much in question. Images provided by Pivotal Weather.
Monday: Morning clouds, then becoming partly to mostly sunny in the afternoon. High 33-40.
Monday night: Clear skies. Low 20-27.
Tuesday: Plenty of sunshine. High 33-40.
Tuesday night: Clear skies, some clouds start to move in late at night. Low 24-31.
Wednesday: Sunshine and a few clouds. High 37-44.
Thursday: Mostly cloudy, breezy, chance for a few rain or snow showers. High 36-43.
Friday: Mostly sunny, breezy, cooler. High 32-39.

Thanksgiving week has arrived, but before we get to the holiday we’ve got a complicated forecast.
Better find the winter gear, temperatures will drop into the teens in some places Tuesday morning. Image provided by WeatherBell.
The week starts off simple enough with high pressure bringing us sunshine and cool conditions. It’ll be breezy at times, making it feel even cooler, with wind chills in the 20s and lower 30s. Tuesday starts off chilly, but we’ll see clouds start to move in as low pressure heads towards the Great Lakes. A secondary area of low pressure will develop off of the Mid-Atlantic coast Tuesday evening, passing near or just south of the South Coast on Wednesday while the main low passes by to the north. They’ll combine to bring us a windy and wet day on Wednesday, also known as the busiest travel day of the year. However, the rain and wind isn’t the entire story. We’ve left out a big detail, one that many of you probably won’t like. The precipitation will move in towards midnight Tuesday night, and temperatures at that time will probably be close to freezing. That means that it will likely start as snow (or sleet), especially north and west of Boston. Once you get outside of I-495, there could even be some accumulation before the change to rain washes everything away. Once you get into the hills of Worcester County and the Monadnocks of southwestern New Hampshire, there could be a few inches before the changeover. Yes folks, it’s that time of year, whether you like it or not, to use an overused phrase – “Winter is Coming.”
Most of the accumulating snow will be well north and west of Boston Tuesday night. Images provided by Pivotal Weather.
The rain tapers off Wednesday afternoon, but likely doesn’t completely end until evening, but then high pressure builds in with sunshine and cool temperatures again for Thanksgiving. So, if you’re traveling locally, you shouldn’t have any issues, but if you’re heading out to one of the high school football games make sure you dress appropriately, because it will be on the chilly side. Friday looks similar to Thanksgiving with dry and cool conditions once again, but the weekend isn’t looking as nice. Another system will likely move up the coast, and this one *should* be mostly rain, but the various forecast models don’t agree on much with this storm, including how strong it will be, the track it will take, or even whether it will impact us on Saturday or Sunday or not at all. We’ll take a deeper dive on that system when we publish our Weekend Outlook, which will be out on Wednesday this week instead of the usual Thursday.

Monday: Plenty of sunshine, a little breezy at times. High 34-41.
Monday night: Clear skies through the evening, some clouds start to move in after midnight. Low 18-25.
Tuesday: Becoming mostly cloudy. High 36-43.
Tuesday night: Cloudy and becoming windy snow developing around midnight north and west of Boston, changing to sleet and rain before daybreak, rain developing elsewhere. Low 30-37 during the evening, temperatures rise after midnight.
Wednesday: Cloudy and windy with rain likely, possibly heavy at times in the morning, tapering off to showers by early afternoon, ending in the evening. High 46-53, possibly a little warmer across southeastern Massachusetts and Cape Cod.
Thanksgiving: Mostly sunny, breezy. High 43-50.
Friday: Partly sunny. High 42-49.
Saturday: Mostly cloudy, breezy, chance of rain. High 39-46.
Sunday: Partly to mostly cloudy, breezy, chance of rain. High 39-46.
As Metallica sings in the beginning of the song “All Nightmare Long”, luck does indeed run out. After getting lucky for nearly the entire winter without a major snowstorm, it appears that our luck has finally run out.
Today will be the literal calm before the storm with high pressure sliding off to the east, but still keep us dry despite plenty of cloudcover. After that, we turn our eyes to a developing low pressure system moving up the East Coast. This will likely be a potent storm when it gets up here, producing strong winds and quite a bit of precipitation. It’s also expected to stall out and perhaps make a bit of a loop, which means we’re looking at a long-duration storm, starting this evening, and likely not ending until Wednesday morning. That’s what we’re fairly certain about. What we’re not certain about is the actually track the storm takes, and where it stalls/makes a loop, and that is the most critical part of the forecast. Temperatures will be marginal to begin with, so a degree or two will make a huge difference. We’re not worried about any warm air aloft, so sleet and freezing rain aren’t a concern – just a good old-fashioned rain/snow line. With marginal temperatures, intensity will also help determine what falls, as lighter precipitation will be more rain than snow, while heavier precipitation will bring some colder air down from aloft, resulting in more snow than rain.
Whether it’s rain or melted snow, this will be a rather juicy storm. Image provided by WeatherBell.
OK, having said all that, he’s our best estimate as to what we expect – low pressure moves up the East Coast, passing just south and east of Cape Cod. Meanwhile, a much weaker secondary low will move across Long Island and southern Connecticut, before it weakens and dissipates. This will help keep temperatures a little warmer, especially near the South Coast, with east to southeast winds. The original rather potent system will then do a loop in the waters just east of New England, before finally moving away on Wednesday. In terms of sensible weather we’re probably looking at nearly all snow north of the Mass Pike and outside of I-495, especially in the hills. South and east of there, precipitation likely starts as rain this evening, gradually changing to snow from northwest to southeast during the day on Tuesday as the system moves off to the east, and strong north to northwest winds bring cooler air in. Those winds will gust to 40-50 mph at times, but luckily tides are astronomically low, so coastal flooding isn’t a widespread concern.
We think the forecast track on the NAM is close to what might happen. Loop provided by Tropical Tidbits.
As for snowfall, we need to make a distinction here between snowfall and snow accumulation. With the increasing sun angle, and the warmer ground, snow will have a hard time accumulating during the daylight hours, especially on paved surfaces, when precipitation is falling lightly. So, it could snow for quite some time, but there won’t be much on the ground. The model forecast maps that people love to share on Facebook and Twitter show snowfall, and as we’ve just said, those maps will not be reflective of what you may see on the ground when this storm winds down. What are we expecting for accumulation?
0-2″ – Outer Cape/Islands 2-4″ – South Coast/Upper Cape/Coastal Plymouth County 4-7″ – I-95 corridor (Providence/Boston), southeastern Massachusetts/North Shore 5-9″ – Metro West/Essex County/NH Seacoast 6-12″ – Merrimack Valley/Southern New Hampshire 8-16″ – Hilly terrain from northwest Rhode Island into central Massachusetts and southwest New Hampshire with isolated heavier amounts possible.
We will note that there are some models that do bring heavier (in some cases MUCH heavier) snow into eastern and especially southeastern Massachusetts. We’re not putting much stock in those. However, if they do end up correct, our snowfall forecast will be off by several orders of magnitude.
Our forecast isn’t that different from what the National Weather Service is forecasting. Image provided by Weathermodels.com
Once this storm pulls away, high pressure builds in with drier and more seasonable conditions for Wednesday night and Thursday. Another system may move in later Friday into Saturday, but this looks like mainly rain, with drier weather again behind that storm on Sunday.
Monday: Mostly cloudy, breezy, showers developing late in the day. High 40-47.
Monday night: Windy with rain likely, changing to snow across southern New Hampshire and central Massachusetts toward daybreak, rain may be heavy at times. Low 32-39.
Tuesday: Windy with rain changing to snow from northwest to southeast during the day. Snow and rain could be heavy at times. High 33-40 early, temperatures hold steady or drop during the day.
Tuesday night: Windy with snow gradually tapering off. Low 27-34.
Wednesday: Mostly cloudy and windy, snow showers ending. High 33-40.
Thursday: A mix of sun and clouds, breezy. High 42-49.
Friday: Becoming mostly cloudy, breezy, showers develop at night. High 45-52.
Saturday: Mostly cloudy, breezy, showers likely, possibly changing to snow before ending at night. High 45-52.
Meteorological spring began yesterday, so naturally, we’ve got a snowstorm on the way for a good chunk of the region.
High pressure builds in tonight with some clearing, but it won’t last too long. Couds quickly move back in on Friday as another storm system moves toward the region. This one will be somewhat similar to the last couple where the main storm system crosses the Great Lakes and heads up the St. Lawrence Valley while a secondary storm develops near the Mid-Atlantic coast and heads offshore south of New England. We’ll see snow developing Friday evening, quickly changing to rain near the South Coast and Cape Cod. Snow will continue overnight, but some warmer air will try to move in aloft, which will likely result in some sleet or rain mixing in. How far north that mixing occurs will obviously have a significant impact on the amount of snow that accumulates. Right now, our best thinking is that the mixing makes it to at least the Mass Pike, possibly up into the Merrimack Valley, during the morning and early afternoon on Saturday. The storm will also produce some gusty easterly winds, which will bring milder air in off the Atlantic, so a change to plain rain is possible near the coastline. By later Saturday afternoon, the system south of New England will pass off to the east, and winds will shift into the northeast and north, bringing cooler air back in, and allowing the precipitation to change back to all snow. While most of the steady snow should wind down towards evening, occasional snow showers may continue through the overnight as what’s left of the original low moves across the region. High pressure then builds in for later Sunday into Monday with dry and seasonably cool conditions.
Another double-barreled low will cross the region this weekend. Loop provided by Tropical Tidbits.
So, how much snow are we expecting?
Cape Cod: 1″ or less South Coast: 1-2″ Southeastern MA/Central+Northern RI: 2-4″ Boston/MetroWest/Notre Shore: 3-6″ Merrimack Valley/NH Seacoast: 4-8″ Southern/Central NH: 5-10″ with isolated amounts in excess of 12″
