Weekly Outlook: May 10-16, 2021

We’ve got a fairly quiet week coming up for the first time in a while.

Low pressure pulls away from the region this morning, with rain coming to an end. We’ll see some clearing this afternoon, but an upper-level low pressure area will move through on Tuesday with more clouds and possibly a shower or two. High pressure builds in for Wednesday and Thursday with generally dry conditions and a warming trend.

The end of the week is a little uncertain at the moment, but it doesn’t look that bad. Another upper-level low will move into the Northeast, so we’ll have more cloudcover at times, with a few showers possible each afternoon. Most of these won’t be that heavy, and they shouldn’t be that widespread, so overall, the weekend shouldn’t be that bad. Temperatures should be on the mild side, likely near to above normal for mid-May.

Monday: Showers end early, some afternoon sunny breaks. High 56-63.

Monday night: Partly to mostly cloudy. Low 40-47.

Tuesday: Intervals of clouds and sun, chance for a shower or two, breezy. High 57-64.

Tuesday night: Partly cloudy. Low 37-44.

Wednesday: A mix of sun and clouds. High 56-63.

Thursday: Sunshine and some afternoon clouds. High 62-69.

Friday: A mix of sun and clouds, chance for an afternoon shower. High 63-70.

Saturday: Partly sunny, showers possible during the afternoon. High 64-71.

Sunday: Intervals of clouds and sun, chance for a few showers. High 64-71.

Weekly Outlook: May 3-9, 2021

This is definitely not shaping up to be a great week to be on vacation, but it is shaping up to be a decent week to put another dent in our developing drought.

Rainfall has been well below normal across the region for several months. Image provided by the Northeast Regional Climate Center.

A cold front moved through late yesterday, and it will stall out south of the region today. With the front nearby, we’ll have plenty of clouds around today, with temperatures that are much cooler than we had on Sunday. We could see a few breaks of sun, but in general, clouds will dominate. By late in the day, we’ll see some more showers moving in as a wave of low pressure rides along that frontal boundary. Those showers should come to an end Tuesday morning, but again, we’ll still have lots of clouds around, with temperatures possibly becoming quite cool behind that wave. Another wave will approach during Tuesday night and Wednesday. This wave may lift the front northward, allowing milder air to move back in to at least part of the region. That wave moves offshore on Wednesday, bringing an end to the rain and dragging the front much farther offshore. High pressure then builds in for Thursday with some sunshine and seasonably mild temperatures. Thursday will definitely be the pick of the week.

Temperatures will be near to below normal across most of the region this week. Image provided by WeatherBell.

As we head into the end of the week and the weekend, things get unsettled again. A coastal storm will likely impact the region, but the models don’t completely agree yet on what that impact will be, or exactly when it will be. Friday and/or Saturday will likely feature a period of rain, possibly heavy, some gusty winds, and cool temperatures. How much rain, how much wind, and how cool it will be are details that we don’t have a good handle on yet. In fact, at least one model shows the potential for some wet snow to mix in, especially over the hills of central New England. While this wouldn’t be unheard of this late in the season, we’re not expecting it to occur, though we’re not completely ruling it out either. As for next Sunday, the coastal storm should be out of the picture, but another system may be approaching from the west, as our active pattern is expected to continue for quite some time.

There is plenty of disagreement among the models in regard to a potential storm system late this week. Images provided by Pivotal Weather.

Monday: Plenty of clouds with showers possible late in the day. High 54-61 along the coast, 61-68 inland.

Monday night: Cloudy with showers likely. Low 44-51.

Tuesday: Showers end in the morning, remaining mostly cloudy in the afternoon. High 55-62, potentially turning much cooler during the afternoon.

Tuesday night: Cloudy with showers redeveloping. Low 43-50.

Wednesday: Showers ending by midday, some sunny breaks are possible late in the day. High 58-65, cooler along the coast

Thursday: A mix of sun and clouds. High 58-65.

Friday: Cloudy with showers possible. High 53-60.

Saturday: Partly to mostly cloudy, chance for showers. High 55-62.

Sunday: Mostly cloudy with a chance of showers. High 57-64.

Weekly Outlook: April 26 – May 2, 2021

In our Weekend Outlook, we mentioned the potential for a significant warmup later this week. Well, that was a bit premature.

We start the week off with high pressure building in behind yesterday’s storm system. We’ll still have breezy conditions in the wake of the system, especially during the morning and early afternoon. With an upper-level low pressure area also moving across the Northeast, some clouds may pop up during the afternoon as well. As the upper low pulls away on Tuesday we’ll have some sunshine, less wind, and milder temperatures.

Wind gusts of 30 mph or higher are possible today. Image provided by WeatherBell.

A warm front moves into the region late Tuesday night, with some showers and possibly a thunderstorm accompanying it. This sets up a very mild day on Wednesday, with much of the region getting well into the 70s, and some 80-degree readings possible well inland. The warmth won’t last long though, as a cold front will be approaching the region later in the day, producing another round of showers and possibly thunderstorms.

Wednesday looks like it will be the warmest day of the week. Image provided by Weathermodels.com

After that, things get a little complicated, as the models don’t agree on exactly how the pattern evolves. That cold front stalls out near or just south of the region Wednesday night. Another wave of low pressure rides along that front, bringing in another round of showers on Thursday. Will that wave lift the front back through as a warm front or not? That’s a critical question for the temperature forecast. The showers look like they will linger into Friday with mild temperatures before a stronger cold front moves through late in the day. Saturday looks to be drier and cooler with high pressure building in, but another upper-level low moves through, with more clouds and possibly a shower or two. Sunday looks milder as high pressure moves offshore and a southwesterly flow redevelops. However, another system could be approaching the region from the west. Whether the shower activity ahead of that system arrives late in the day Sunday or on Monday is a detail that can’t be resolved this far out.

Temperatures on Thursday will be highly dependent on where the front is located. Images provided by Pivotal Weather.

Monday: Partly to mostly sunny and breezy. High 53-60.

Monday night: Partly cloudy. Low 34-41.

Tuesday: A mix of sun and clouds. High 63-70.

Tuesday night: Partly to mostly cloudy with a few showers possible, maybe even a rumble of thunder. Low 43-50.

Wednesday: Intervals of clouds and sunshine, showers and thunderstorms possible late in the day and into the evening. High 69-76, cooler along the coast.

Thursday: Plenty of clouds with showers likely. High 56-63.

Friday: Mostly cloudy and breezy with more showers. High 59-66.

Saturday: Partly sunny. High 56-63.

Sunday: A mix of sun and clouds, breezy, chance for a few late-day showers. High 57-64.

Weekly Outlook: April 19-25, 2021

It’s Patriots Day in Massachusetts, and although the Marathon won’t be held until October, there’s still plenty going on today, and the weather should cooperate for the most part.

The day will start off with some sunshine and seasonably mild temperatures, but an upper-level disturbance will cross the Northeast today, allowing for some clouds, and probably a few showers, maybe even a thunderstorm, this afternoon. They shouldn’t be widespread, nor heavy, but given that we still have a significant rainfall deficit, every little bit helps. A cold front will move through on Tuesday, but with little fanfare aside from some clouds and possibly a shower or two. Ahead of it, temperatures will be quite mild, possibly topping 70 in some locations. That front will stall out near or just south of the South Coast Tuesday night, then lift back northward as a warm front on Wednesday as low pressure passes north and west of the region. With low pressure to our northwest, it’ll be quite mild again, but another cold front will approach from the west, producing another round of showers and thunderstorms.

Temperatures could reach 70 in many areas on Tuesday. Image provided by WeatherBell.

Behind that front, high pressure builds in with much cooler conditions on Thursday and to a lesser extent on Friday. A few weak upper-level disturbances will also be moving through with some clouds at times, but little precipitation other than a stray shower. Next weekend looks unsettled, but the details are still a little fuzzy. A period of rain or showers and cool temperatures appears likely at some point, but will it be late Saturday and Saturday night as one model shows, or on Sunday as a different one indicates? We should have a better handle on that when we do our Weekend Outlook on Thursday.

Year-to-date rainfall totals are running 4-6 inches below normal across much of the region. Image provided by the Northeast Regional Climate Center.

Monday: Early sun, then clouds develop, with a few showers or thunderstorms possible in the afternoon. High 61-68, coolest along the coast.

Monday night: Clear to partly cloudy. Low 38-45.

Tuesday: A mix of sun and clouds, breezy, just a slight chance for a late-day shower. High 64-71.

Tuesday night: Partly cloudy. Low 41-48.

Wednesday: Becoming mostly cloudy and breezy with showers likely, possibly a thunderstorm, ending in the evening. High 59-66.

Thursday: Plenty of clouds with a slight chance for a shower, windy and much cooler. High 43-50.

Friday: Intervals of clouds and sunshine, breezy. High 53-60.

Saturday: Early sun, then clouds return with showers possible late in the day and at night. High 60-67.

Sunday: Cloudy with a chance of rain. High 53-60.

Weekend Outlook: April 16-19, 2021

It’s not April 1, and this isn’t a joke – there’s snow in forecast for parts of our area.

Low pressure is moving off the Mid-Atlantic coast this afternoon while an upper-level low pressure area moves in from the west. The upper-level low will draw the surface low northward towards southeastern New England while it intensifies. Rain is spreading across the region this afternoon, and it will become steadier and heavier tonight as the low moves up the coast. With the upper-level low moving in, we’ll have some very cold air aloft. As the rain becomes heavier, it will pull the cold air down from above, a process called “dynamic cooling”. As this occurs Friday morning, we’ll see the rain change over to snow across the hills from northwestern Rhode Island and central Massachusetts into southwestern New Hampshire. Some wet snow may mix in across the lower elevations of southern New Hampshire and northern Massachusetts as well but we’re not expecting much, if any, accumulation, and what does accumulate will be mainly on grassy surfaces because the pavement is too warm, and air temperatures won’t drop below freezing. It’ll be a different story across the hills from Worcester County into the Monadnocks of southwestern New Hampshire, where several inches may accumulate. Even heavier snow is possible for the Berkshires and the Green Mountains of Vermont. We should note that there are some models that are forecasting accumulating snow, and in some cases quite a bit of it, across most of eastern Massachusetts and Rhode Island. While we can’t completely rule out this scenario, we’re not expecting it to occur.

Most of us won’t see much, if any, snow from this system. Image provided by WeatherBell.

The surface low will pass near or over Cape Cod or southeastern Massachusetts Friday afternoon, allowing any mixed precipitation to change back to all rain and milder air moves in. The rain will taper off to showers in the afternoon, but the showers may not completely end until early Saturday as the system slowly starts to move away. Given the recent lack of rainfall, we’re starting to see drought conditions develop. With 1-2 inches of rain expected from this storm, we’ll help put a nice dent in that developing drought.

Much-needed rain is expected over the next 48 hours. Image provided by Weathermodels.com

Saturday won’t be quite as chilly as Friday, but we probably won’t see much sunshine either as the system only slowly moves away. High pressure starts to build in on Sunday with more clearing and milder temperatures. However, an upper-level disturbance will be moving through, so a couple of pop-up showers can’t be ruled out. Patriots Day on Monday is shaping up to be a nice Spring day with partly sunny skies and mild temperatures, but again, a pop-up shower can’t be ruled out as another weak upper-level disturbance crosses the region.

Monday looks to be a mild day. Image provided by WeatherBell.

Thursday night: Periods of rain, possibly heavy at times, changing to snow across the hills from northwestern Rhode Island and central Massachusetts into southwestern New Hampshire, breezy. Low 33-40.

Friday: Windy with rain mixed with snow at times in the morning, tapering off to showers during the afternoon. High 37-44, possibly a little warmer south of Boston.

Friday night: Cloudy and breezy with showers ending. Low 33-40.

Saturday: Plenty of clouds, possibly a few showers near the coast, some sunny breaks may develop in the afternoon. High 44-51.

Saturday night: Partly to mostly cloudy. Low 32-39.

Sunday: Intervals of clouds and sunshine, slight chance for a shower. High 49-56.

Sunday night: Clear to partly cloudy. Low 33-40.

Monday: Partly sunny, slight chance for a shower. High 56-63.

Weekly Outlook: April 12-18, 2021

One of our colleagues called the current weather pattern a “quiet active pattern”, which is a very good way to describe the week ahead.

In the big picture, we’ve got an upper-level low pressure area in place for today into Tuesday before it moves out, but another one moves in for the end of the week and the start of the weekend. Looking a little closer, we’ve got some typical April weather, but since this is New England and not Florida, a lot of you probably won’t like it. Low pressure passes south of the region today into early Tuesday, with plenty of clouds around and a chilly east wind off the Atlantic. Some showers are possible, mainly today, but we’re not looking at widespread rainfall. Wednesday looks a little drier as high pressure tries to build in with some partial sunshine and mild temperatures.

Temperatures will average close to normal around here over the next week. Image provided by WeatherBell.

The end of the week isn’t looking pretty at this point. As that second upper-level low pressure area moves eastward on Thursday, a low pressure area will likely spin up at the surface near the Mid-Atlantic coastline. As it gets caught up under the upper-level low, it will meander around near or just south of New England. The result will be chilly conditions, some gusty winds at times, and periods of rain from later Thursday into Saturday. But that’s not the entire story. With colder air aloft, we could see the rain change over to snow, with some accumulation in the higher terrain, such as the hills from northwestern Rhode Island into Worcester County and the Monadnocks of southwestern New Hampshire. Could we see snow mix in at lower elevations? Sure, it’s possibility, but accumulations aren’t likely (though not impossible). Remember, it was this same weekend last year (April 17-18), when we had a storm drop 3-6″ of snow on the hills, with up to an inch of snow across the rest of eastern Massachusetts and Rhode Island. We’ll obviously have a better handle on this situation when we do our Weekend Outlook on Thursday.

Models are showing the potential for snow, especially in the hills, at the end of the week. Images provided by Pivotal Weather.

Once the system pulls away, conditions will slowly improve over the weekend as high pressure starts to build in.

Monday: Cloudy and breezy with a few showers possible. High 44-51.

Monday night: Partly to mostly cloudy. Low 35-42.

Tuesday: Plenty of clouds with a few sunny breaks. High 52-59, cooler along the coast.

Tuesday night: Mostly cloudy. Low 37-44.

Wednesday: Intervals of clouds and sunshine. High 54-61, cooler along the coast.

Thursday: Cloudy and breezy with showers developing, possibly changing to snow in the hills at night. High 49-56.

Friday: Windy with periods of rain, possibly mixed with snow at times, especially in the hills. High 35-42 north and west of Boston, 43-50 south of Boston.

Saturday: Cloudy with showers gradually ending. High 47-54.

Sunday: Partly sunny. High 54-61, cooler along the coast.

Weekly Outlook: April 5-11, 2021

Much of this week will feature conditions that are fairly typical for April in New England. That’s good if you live away from the coastline. Near the coast? No so much.

Low pressure south of Nova Scotia was sending clouds into eastern New England early this morning. Loop provided by NOAA.

The week starts off with low pressure off to the east slowly drifting southward. This will keep clouds in place across eastern New England with a few showers possible. We’ll also have northeast winds blowing off the still-chilly Atlantic, resulting in cool temperatures. The farther inland you head, the more likely you are to see sunshine and temperatures that are warmer than normal. Tuesday looks somewhat similar, but as the low pulls away, the small chance for showers we have today goes with it. High pressure then builds in for Wednesday through Friday with sunshine for much of the region along with seasonably mild temperatures.

Drought conditions are starting to develop across parts of the Northeast once again, so we need some rain. Image provided by the National Drought Mitigation Center.

Next weekend is where things get tricky again. High pressure will slide offshore on Friday as low pressure starts to approach from the southwest. For the weekend, there are some models that show the high remaining in place, keeping the region dry, but trending cooler. Other models have the rain from the system moving in, resulting in a damp and cool weekend. We’re going to lean on the dry side for now with the forecast, but obviously, the other scenario is just as plausible, so this is a low-confidence forecast. We should have a much better idea by the time we get to our weekend outlook on Thursday.

Will it rain this weekend? Some models say yes, some say no. Image provided by Weathermodels.com

Monday: Intervals of clouds and sunshine, breezy, chance for a few showers along the coast. High 53-60, a little cooler along the coast.

Monday night: Partly to mostly cloudy. Low 35-42.

Tuesday: Partly sunny. High 52-59, a little cooler along the coast.

Tuesday night: Partly cloudy. Low 35-42.

Wednesday: A mix of sun and clouds. High 49-56 along the coast, 57-64 inland.

Thursday: Partly to mostly sunny. High 48-55 along the coast, 56-63 inland.

Friday: Partly to mostly sunny. High 49-56 along the coast, 57-64 inland.

Saturday: Mostly sunny. High 52-59, a little cooler along the coast.

Sunday: Sunshine and a few clouds. High 51-58, a little cooler along the coast.

Weekly Outlook: March 29-April 4, 2021

While there will be a couple of chilly days this week, we’ve also got some more typical spring weather coming, and the best sign yet that winter is just about done – Red Sox Opening Day!

We start the week off on a breezy and chilly note in the wake of a cold front with high pressure building into the region. Wind Advisories and High Wind Warnings are in effect through this afternoon. Sustained winds of 20-30 mph with gusts of 40-50 mph or higher are possible. Temperatures will be below normal for late March, with the wind making it feel even colder, but the chill won’t last long. High pressure moves off to the east on Tuesday and we quickly see temperatures start to moderate.

Wind gusts of 40-50 mph or higher are possible, mainly this morning and early afternoon. Image provided by WeatherBell.

Wednesday looks to be milder, but clouds will be streaming back in as another storm system moves toward the region. This system will bring in some showers by Wednesday afternoon, with some steady rain possible at night into Thursday morning. The rain looks to end by midday, with much cooler air moving in behind the system. This may allow the rain to mix with wet snow before ending. Of course, when the rain (or mix) ends is crucial, since first pitch at Fenway is scheduled to take place just after 2pm. Right now, it looks cloudy with some sunny breaks possible before the game ends. Temperatures will only be in the lower 40s, with wind chills in the 30s. Not exactly baseball weather, but not out of the ordinary for April 1.

Thursday is Opening Day, and the Red Sox can’t possibly be as bad as last year, right? Image provided by Major League Baseball.

High pressure builds back in on Friday with colder weather, but again, it will be short-lived. As the high moves offshore, temperatures will moderate back to near to above normal levels next weekend.

Monday: Becoming mostly sunny and windy. High 45-52.

Monday night: Clear skies. Low 25-32.

Tuesday: Sunshine and a few afternoon clouds, breezy. High 54-61, cooler along the South Coast and Cape Cod.

Tuesday night: Partly cloudy. Low 37-44.

Wednesday: Becoming mostly cloudy and breezy with showers developing in the afternoon, becoming a steady rain at night. High 60-67, cooler along the South Coast and Cape Cod.

Thursday: Cloudy with rain, possibly mixed with some wet snow, ending around midday. High 49-56 in the morning, temperatures drop into the 40s during the afternoon.

Friday: Partly sunny and chilly. High 37-44.

Saturday: A mix of sun and clouds. High 46-53.

Sunday: Partly sunny. High 53-60.

Weekly Outlook: March 22-28, 2021

We’ve got a fantastic stretch of weather coming up for a good chunk of the upcoming week thanks to a large area of high pressure.

Dry and mild conditions are expected through at least the first part of Wednesday thanks to a large area of high pressure. Along the coast, temperatures will be cooler, thanks to a seabreeze each of the next few afternoons, but once you get inland, temperatures should reach the 60s each day. Things could be a little tricky on Wednesday however. Low pressure will meander off to the south for the first half of the week, with little impact on us. However, by late Wednesday it will start to lift out, sending some clouds in along with the possibility of a few showers. If the showers are more widespread than we currently expect or the clouds are thicker, temperatures could end up quite a bit cooler than our forecast currently shows.

A little rain is possible late Wednesday, but not all of the models agree on it. Images provided by Pivotal Weather.

High pressure then builds back in south of the region, resulting in southwesterly winds bringing even milder air in for Thursday, possibly right to the coastline. Unfortunately, we’ll also have more cloudcover, as another low pressure area makes its way into the eastern Great Lakes. With enough sunshine, temperatures could top 70 degrees in many spots. That system will bring us some rain for Thursday night into Friday as it passes to our north and west, before a cold front crosses the region during the day on Friday. Friday’s temperatures will be dependent on the timing of the front, the later it moves through, the more likely that it’ll be warmer. If the rain lingers long enough and the cold air moves in fast enough, some wet snow could mix in before everything winds down. We don’t expect this to be the case, but can’t completely rule it out just yet.

Temperatures could reach 70 on Thursday, depending on how much sunshine we get. Image provided by WeatherBell.

Behind that front, more seasonable conditions are expected for Saturday, but Sunday is where things could get interesting again. Another low pressure system will head toward the region, with some rain possible by late Sunday or Sunday night. The problem is, we’ll have some cold air nearby, so it may not be just rain, at least for part of the region. There’s a chance we could have some snow from this system, especially the farther north and west you go from Boston. This is hardly a lock, and things will change numerous times between now and then, but it’s just another example that even though it’s now Spring, that doesn’t mean we’re entirely done with Winter just yet.

Monday: Lots of sunshine. High 57-64, cooler along the coast.

Monday night: Clear skies. Low 30-37.

Tuesday: Sunshine and some afternoon high clouds. High 57-64, cooler along the coast.

Tuesday night: Partly cloudy. Low 33-40.

Wednesday: Thickening clouds with some showers possible during the afternoon and evening. High 52-59, cooler along the coast.

Thursday: More clouds than sunshine. High 62-69, cooler along the South Coast and Cape Cod.

Friday: Cloudy and breezy with showers likely, possibly mixing with wet snow before ending at night. High 58-65, cooler along the South Coast and Cape Cod.

Saturday: Intervals of clouds and sun, cooler. High 53-60.

Sunday: Early sun, then becoming cloudy with rain possible late in the day and at night, possibly mixed with some wet snow well to the north and west. High 49-56.

Weekly Outlook: March 15-21, 2021

Astronomical Spring officially begins Saturday morning at 5:37am, but it’s going to feel likely winter for a couple more days.

Spring begins Saturday morning. Image provided by EarthSky.org

Most of this week will be fairly dry, as today will be with high pressure building in. Today will also be quite cold, with many places likely not reaching the 30-degree mark. Add in a little wind, especially this morning, and it definitely won’t feel like mid-March, with wind chills in the single numbers and teens. As the high slides off to the east, temperatures will start to moderate a bit on Tuesday, but it will remain on the chilly side. Clouds will also start to move back in ahead of a weak low pressure system. That system will pass to sour south Tuesday night and Wednesday, but may produce a few snow showers, especially near the South Coast. We’re not expecting anything to accumulate, and for the bulk of the region, we’re not expecting much, if anything, to even fall from the clouds.

Temperatures will be 15-20 degrees below normal today. Image provided by Weathermodels.com

We’ll see some sunshine return on Wednesday to parts of the area along with temperatures continuing to moderate. However, the next system moves in for Thursday into Friday. This one doesn’t look as weak or as far south, but temperatures will be a bit milder to start. We could see some rain or snow showers, especially Thursday night into Friday morning, especially south of the Mass Pike, but again, this does not look like a big deal. Colder weather will settle in on Friday as the system pulls away, but temperatures will moderate again over the weekend thanks to high pressure building back in.

Some models show the possibility for a little snow Thursday night into Friday. Images provided by Pivotal Weather.

Monday: Partly to mostly sunny and breezy, especially in the morning. High 23-30.

Monday night: Clear to partly cloudy. Low 9-16.

Tuesday: Early sun, then thickening clouds. High 34-41.

Tuesday night: Partly to mostly cloudy with some snow showers possible, mainly south of the Mass Pike. Low 23-30.

Wednesday: Mostly cloudy, some sunny breaks are possible across southern New Hampshire. High 43-50.

Thursday: Plenty of clouds with some showers possible, maybe mixing with snow at night. High 49-56.

Friday: Mostly cloudy, breezy, and colder, with a chance of snow showers. High 33-40.

Saturday: A few clouds early, otherwise mostly sunny. High 42-49.

Sunday: Lots of sunshine, milder. High 47-54.
