Now that Spring has officially arrived, cooler weather will return.

The week starts off with high pressure building into eastern Canada, providing us with sunshine and seasonably cool conditions for today and Tuesday. By Wednesday, that high will start to slide eastward as low pressure heads toward the Great Lakes, sending some clouds our way. Precipitation looks to spread in Wednesday night, and there may be enough cold air in place that allows it to start as some snow or a wintry mix, at least across the interior. Everything should go over to plain rain on Thursday, and some of it could be heavy as a secondary area of low pressure develops nearby and moves right across the region. Rain ends early Friday as that low pulls away, but with another upper-level low pressure area slowly moving in, we’ll start have a decent amount of cloud cover along with the threat of some pop-up showers Friday afternoon. For the weekend, that upper-level low will cross the Northeast, and a new area of low pressure will develop at the surface near the Mid-Atlantic coast. While the surface low may be too far offshore to have much impact, it may interact with the upper-level low to produce some additional rain or snow showers next weekend.

Monday: Sunshine and a few afternoon clouds, breezy. High 47-54.

Monday night: Clear to partly cloudy. Low 29-36.

Tuesday: Partly to mostly sunny and breezy. High 43-50.

Tuesday night: Clear to partly cloudy. Low 25-32.

Wednesday: Some sun in the morning, then clouds move in during the afternoon with rain or snow showers developing in the evening. High 41-48.

Thursday: Cloudy with rain likely, possibly some wintry mix across the interior during the early morning. High 42-49.

Friday: Rain ends early, otherwise plenty of clouds and a few sunny breaks, slight chance for an afternoon shower. High 52-59.

Saturday: More clouds than sunshine with a rain or snow shower possible. High 47-54.

Sunday: Partly to mostly cloudy with a chance for a few rain or snow shower. High 45-52.

Astronomical spring begins on Sunday at 11:33am, but we’re already 2 weeks into meteorological spring, and this week it will feel like it.

High pressure slides offshore today, allowing for milder air to move back into the region. Tuesday looks to be mild as well, but a cold front will be dropping southward with a weak area of low pressure riding along it. This may bring in a few showers Tuesday night, possibly even mixed with a little wet snow across central and southern New Hampshire. That front will stall out nearby, so areas to the south may stay mild on Wednesday, but much of the region will be on the cooler side, though still a little above normal for mid-March. Thursday looks to be similar with some clouds and possibly even a few showers as another low pressure system passes by to the south. This brings us to Friday, which is most definitely the pick of the week.

Low pressure will head into the Great Lakes, sending a warm front across the region. With some sunshine and southwesterly winds, temperatures should get well into the 60s away from the South Coast, with lower 70s possible. Saturday’s forecast is a bit trickier. That storm system will head into southeastern Canada, with 1 of 2 things possibly happening – We could have another very warm day with showers developing ahead of a cold front or a secondary area of low pressure develops off the Mid-Atlantic coast, resulting in more rain and significantly cooler temperatures. We’re going to lean towards the first scenario for now, but are cognizant of the fact that the second one is just as likely to happen. Either way, Sunday looks drier and seasonably cool.

Monday: Sunshine and some afternoon clouds. High 47-54.

Monday night: Mostly cloudy. Low 34-41.

Tuesday: Plenty of clouds with a few late-day showers possible, mainly north of the Mass Pike. High 55-62, a little cooler across southern New Hampshire.

Tuesday night: Mostly cloudy with showers during the evening north of the Mass Pike, possibly mixed with snow across southern New Hampshire. Low 32-39.

Wednesday: Becoming partly to mostly sunny. High 51-58, cooler along the coast.

Thursday: Intervals of clouds and sun, chance for a shower, especially near the South Coast. High 56-63.

Friday: A mix of sun and clouds. High 64-71, cooler along the South Coast.

Saturday: Cloudy and breezy with showers likely, ending in the afternoon. High 50-57.

Sunday: Partly sunny, breezy, and cool. High 51-58.

As you’d expect as we get into Spring, things will change quite a bit this week.

Low pressure will pass across New England today, bringing some rain in, mainly this afternoon and evening. With temperatures remaining mild, especially across Massachusetts, there’s even the potential for a rumble of thunder. The system pulls away tonight, setting up a sunny but breezy and cooler day on Tuesday. Another system passes by to the south on Wednesday, close enough for some clouds, but most of the precipitation with the system likely stays south of New England, though we could see a rain or snow shower reach the South Coast. By Thursday, we’ll start to turn milder once again as high pressure slides offshore, setting up the end of the week and the weekend.

On Friday, low pressure will start to head up the Ohio Valley, crossing the Northeast on Saturday as it intensifies. We should be breezy and mild ahead of it, with rain likely Friday night into Saturday. Some of the models show the potential for very strong winds and potentially some heavy rain, but it’s still 5-6 days away, so for now it’s just potential. The system drags a cold front through later on Saturday, which may allow the rain to end as snow across the region, then windy and colder weather settles in for Sunday.

Monday: Cloudy and mild with periods of rain and showers during the afternoon. High 53-60, except 45-52 across southern New Hampshire.

Monday night: Rain during the evening, possibly a rumble of thunder, some clearing after midnight, breezy. Low 29-36.

Tuesday: Mostly sunny and breezy. High 39-46.

Tuesday night: Clear during the evening, clouds start to move in late at night. Low 20-27.

Wednesday: Plenty of clouds, just a slight chance for a rain or snow shower along the South Coast and Cape Cod. High 39-46.

Thursday: Partly sunny. High 46-53.

Friday: Morning sun, clouds move in during the afternoon, showers develop late at night. High 47-54.

Saturday: Cloudy and windy with rain likely, possibly mixing with wet snow before ending at night. High 53-60.

Sunday: A mix of sun and clouds., breezy, and colder. High 30-37.

We’ve got a little bit of everything coming this week, unseasonably warm air (again), a snowstorm (again), some rain (again).

The week starts off with high pressure sliding offshore, allowing mild weather to return to the region today, with high temperatures likely topping 50 in many areas. Clouds start to stream in by late in the day though as low pressure heads toward the region. That low pressure system will pass north and west of the area later Tuesday, with gusty southwest winds bringing in very warm conditions in for Tuesday into Wednesday, with many places possibly topping 60 degrees on Wednesday. There are some indications that the warm air may struggle to move into southern and central New Hampshire on Tuesday, possibly holding off until Tuesday night, which may allow for a little freezing rain Tuesday evening. With the warm air comes some rain later Tuesday and Tuesday night, into early Wednesday morning. The rain ends when a strong cold front moves through, with skies clearing in the afternoon. High pressure builds in for Thursday with dry and cold conditions.

Another storm system moves into the Ohio Valley before redeveloping off the Mid-Atlantic coastline for Thursday night and Friday. There are still plenty of variables to be determined, but with colder air in place, we’ll likely see some snow to start. How much snow, and whether it changes over to sleet, freezing rain, and/or rain are questions that we cannot answer yet, but there is the chance for several inches of snow for at least part of the region. High pressure builds back in next weekend with dry and chilly conditions.

Monday: Sunshine filtered through some high clouds at times. High 47-54.

Monday night: Increasing clouds. Low 26-33.

Tuesday: Some sunny breaks early, otherwise mostly cloudy and becoming breezy with showers developing in the afternoon. High 47-54, except possibly cooler across central and southern New Hampshire.

Tuesday night: Cloudy and windy with rain likely, possibly some freezing rain in parts of central or even southern New Hampshire for a while during the evening. Temperatures holding steady or rising overnight.

Wednesday: Lingering showers end early, clearing in the afternoon, breezy, and warm. High 58-65.

Thursday: Mostly cloudy and much colder, snow develops at night. High 31-38.

Friday: Breezy with snow likely, possibly mixing with or changing to sleet, freezing rain and plain rain, ending in the evening. High 30-37.

Saturday: Partly sunny and cold. High 25-32.

Sunday: Sunshine gives way to afternoon clouds. High 31-38.

Much of the upcoming week will be dry and mild, but there are some exceptions.

A weak low pressure system will pass south and east of New England later today and tonight. It will spread some light rain into the area, though temperatures will be marginally cold enough for some light snow across the interior, mainly north and west of I-495. Rain ends late tonight, followed by gradual clearing on Tuesday. After that, we’ll have generally dry and mild weather through the remainder of the week, though some disturbances will spread in some clouds and possibly a few showers at times. We may turn colder again next weekend, but there are no big storms in sight.

Monday: Cloudy with showers developing, mixed with snow across the interior. High 35-42.

Monday night: Cloudy with rain or snow showers gradually ending. Low 29-36.

Tuesday: Any lingering showers end early, skies start to clear out late in the day. High 38-45.

Tuesday night: Clear skies. Low 17-24.

Wednesday: Sunshine and a few afternoon clouds. High 35-42.

Thursday: Intervals of clouds and sunshine, slight chance for a shower. High 42-49.

Friday: Partly to mostly sunny. High 37-44.

Saturday: Partly sunny. High 42-49.

Sunday: More clouds than sun, much cooler. High 28-35.

After a snowy weekend, quiet weather will settle in for a few days.

The week starts off on a rather chilly note with high pressure in control, but as it slides off to the east, temperatures will moderate for the next few days. By Wednesday, many locations could top 40 degrees. This will help to melt some of the mounds of snow across the region, but remember, with temperatures dropping below freezing at night, anything that melts will ice back up.

The next storm system approaches on Thursday, and it looks a bit complicated. A cold front will bring colder air back into the region and a wave of low pressure will ride along it, possibly passing south of the region. With warmer air in place to start, we will likely see precipitation start as rain, but a change to sleet and/or freezing rain is possible, especially across the interior during Thursday night and Friday. We could see a change to snow before everything winds down Friday afternoon. We’ll obviously have a better handle on this storm later this week. High pressure then builds in for the weekend with cold and dry conditions.

Monday: Sunshine and a few clouds. High 24-31.

Monday night: Clear to partly cloudy. Low 4-11.

Tuesday: Partly sunny. High 30-37.

Tuesday night: Partly to mostly cloudy. Low 21-28.

Wednesday: Mostly cloudy. High 38-45.

Thursday: Cloudy with rain developing, changing to sleet and/or freezing rain across the interior. High 39-46.

Friday: Wintry mix possibly ending as snow. Temperatures dropping into the 20s and 30s during the day.

Saturday: Becoming partly to mostly sunny. High 18-25.

Sunday: A mix of sun and clouds. High 25-32.

Another chilly week is expected, but trouble could be lurking next weekend.

A dry, but chilly day is expected today as high pressure builds in, but it won’t stay that way for long. An Alberta Clipper will be heading this way, sending clouds back in late today, with some snow showers late tonight into early Tuesday. Temperatures may be marginally warm enough to change the snow to rain across Cape Cod and the South Coast. Any accumulation should be an inch or less. Once that system moves by, high pressure builds back in for Wednesday and Thursday with much colder weather once again. Another weak system may bring in a few snow showers on Friday as temperatures moderate a bit. This brings us to next weekend.

For several days now, the models have been indicating the potential for a significant storm system somewhere near the East Coast around Saturday, January 29. We’ve mentioned more times than we can count that the models aren’t trustworthy beyond about 2 or 3 days right now, but they have all had the same signal for quite some time, which gives us increased confidence that there will be some sort of storm, and it will probably be potent. However, models are showing little consistency beyond that in terms of how strong it will be, where it will track, what areas (if any) it might impact, and what impacts (if any) that it will have. At this point, everything is on the table, from a swing and a miss with the storm heading out to sea, to an inland runner, where we end up on the warm side with heavy rain and mild temperatures, to a mix of snow, sleet, freezing rain, and rain with the storm tracking right over us, to a full-fledged blizzard with the classic track right up the coast. Depending on which model you look at, and which run of that model, they have all indicated any and all of these scenarios at one point over the past several days. So, at this point, it is impossible to make a forecast, because frankly, we just don’t know, and probably won’t have a better idea of what to expect until at least mid-week. By the time we issue our Weekend Outlook on Thursday, we *should* have a decent idea of what will happen, but even that isn’t definite. So, stay tuned….
