Winter officially ends later this week, but that does not mean that we are done with wintry weather.

The week is starting off on a wet, but mild note as a cold front approaches the region. Rain will taper off to showers this morning, ending this evening as the cold front moves through. The airmass behind the front isn’t that cold to begin with, so although we’ll turn cooler, it won’t be that bad. High pressure builds in for Tuesday with some sunshine and temperatures that are closer to where they should be in mid-March. By Wednesday the high will move off to the east, with a wind off the still-chilly Atlantic bringing some cooler air back in along with some clouds. Another system will also be approaching from the west, but this won’t get here until later Thursday, which happens to be the first day of Spring. The Vernal Equinox occurs at 5:01am Thursday, marking the official end of winter. This front will bring in some rain late Thursday and Thursday night. A wave of low pressure will ride up along the front early Friday, bringing in just enough colder air for the rain to change to snow across the interior before ending. Will there be any accumulation? It’s possible, but it’s still a bit early for that, as we’re not even completely convinced yet that the rain will even change to snow. More details on this system will be forthcoming in our Weekend Outlook on Thursday. High pressure builds in with drier weather later Friday and early Saturday, then another weak system passes by to the south later Saturday and Saturday night with some clouds and possibly a shower or two. Drier weather should return on Sunday.

Monday: Rain during the morning, possibly heavy, tapering off to showers during the afternoon. High 52-59.

Monday night: Showers ending from northwest to southeast. Low 32-39.

Tuesday: Gradual clearing. High 50-57, cooler across east-facing coastal locations.

Tuesday night: Clear to partly cloudy. Low 32-39.

Wednesday: Sunny in the morning, clouds start to move back in during the afternoon. High 51-58, cooler across east-facing coastal locations.

Wednesday night: Becoming mostly cloudy. Low 34-41.

Thursday: Cloudy and becoming breezy with showers possible late in the day. High 51-58, cooler across Cape Cod

Thursday night: Showers likely, possibly changing to snow across the interior late at night. Low 32-39.

Friday: Rain or snow ending, breezy. High 41-48.

Saturday: Sunshine and some afternoon clouds, slight chance for a shower at night, breezy. High 49-56.

Sunday: Becoming partly to mostly sunny. High 49-56.

The active pattern will continue for most of the week with a few more chances for wintry weather.

We’re starting the week out with high pressure in control, giving us sunshine and chilly conditions today. Many places will get above freezing allowing for snow to melt, but as temperatures drop this evening, icy conditions will likely develop on untreated surfaces, so keep that in mind if you are heading out this evening. Clouds will start to move in on Tuesday ahead of another low pressure system. This one will bring snow into the Mid-Atlantic states, but likely passes well south of New England. However, the precipitation field surrounding the storm could get far enough north Tuesday night to bring a little light snow into the South Coast, Cape Cod, and the Islands, possibly as far north as parts of Rhode Island and southeastern Massachusetts. We’re not looking at much snow, just a dusting to perhaps an inch, so it’ll be more of a nuisance than anything else if it happens. High pressure brings drier air in for Wednesday, then things get complicated.

Low pressure will move into the Great Lakes late Wednesday, then into the St. Lawrence Valley Wednesday night and Thursday. We’ll see snow developing ahead of the system Wednesday night, but as warmer air moves in aloft, a change to sleet and then freezing rain is likely. The question becomes – does a secondary area of low pressure develop and pass south of New England early Thursday? If it does, that will keep the cold air in place in the surface, resulting in sleet and freezing rain continuing across the interior, with a change to plain rain south of the Mass Pike. If it doesn’t, then the warmer air eventually moves in at the surface, with a change to plain rain across most of the region before the precipitation ends by midday Thursday. High pressure builds in with drier air for Friday and the first part of Saturday before things get complicated once again.

Another low pressure system will move out of the Great Lakes and into the St. Lawrence Valley later Saturday and Saturday night. We’ll see snow developing late Saturday, likely changing to rain at night. This time, we likely will see a secondary low pressure area develop, but the question is, where does it track. Does it pass south of the region, allowing some colder air to move back in with a change back to sleet or snow? Does it move right across the region, resulting in more rain for much of Sunday? At this point, it’s far too early to try and pin down these type of details, but it does look like, for now at least, that Sunday won’t be a nice day around here.

Monday: Partly to mostly sunny. High 28-35.

Monday night: Clear to partly cloudy. Low 7-14, north of the Mass Pike, 15-22 south of the Pike.

Tuesday: Morning sun, then increasing clouds. High 28-35.

Tuesday night: Mostly cloudy, chance for a little light snow near the South Coast, Cape Cod, and the Islands. Low 9-16 north of the Mass Pike, 17-24 south of the Pike.

Wednesday: Intervals of clouds and sun. High 26-33.

Wednesday night: Cloudy with light snow developing, changing to sleet and freezing rain late at night, possibly all rain south of Boston. Low 18-25, temperatures start rising after midnight.

Thursday: Snow, sleet, freezing rain, or rain ending by midday, some clearing towards evening. High 36-43.

Thursday night: Becoming partly cloudy. Low 16-23.

Friday: Mostly sunny, breezy, colder. High 25-32.

Saturday: Becoming mostly cloudy, light snow developing in the afternoon, changing to rain at night. High 29-36.

Sunday: Cloudy and breezy with rain likely, possibly changing back to sleet, freezing rain, or snow, especially north and west of Boston. High 35-42.

Happy Truck Day to all who celebrate. While it’s a sign that Spring is on the way, Mother Nature won’t be providing too many other signs of Spring this week.

We’re starting the week off on a mild note. The low pressure system that brought us some light snow and rain will drag a warm front through this morning, allowing milder air to flow into the region on south to southwest winds. We’ll see some limited sunshine, but if it ends up being more widespread than we expect, temperatures could jump into the 50s. A cold front moves through tonight, possibly producing some rain showers in a few spots. High pressure builds in behind the system with sunshine accompanied by breezy and cooler conditions on Tuesday. The high will remain in control on Wednesday keeping us seasonably chilly, but clouds will start to stream in during the day ahead of the next storm system. There is a bit of uncertainty with this system, but we’ll likely see some snow developing across the region before daybreak on Thursday. A change to rain is likely south of the Mass Pike, but it’s the area from the Pike northward into southern New Hampshire that is a big question mark. Warmer air will likely move in aloft, allowing for a change to freezing rain and sleet, but how far north does the warmer air get at the surface? Some models bring it all the way into southern New Hampshire with a change to plain rain, some keep the colder air locked in at the surface, with the wintry mix and resulting hazardous travel conditions continuing into the afternoon, and some even keep it all snow across parts of southern New Hampshire and even northern Massachusetts. It’s a little too early to decide which way to lean with this, so we’ll continue to monitor it, and if there is enough of a threat of wintry weather, we’ll write a separate blog about it on Wednesday.

The precipitation winds down later Thursday as the system moves offshore, then high pressure builds in for Friday and Saturday with dry and colder weather. The next system heads out way for late Saturday into at least part of Sunday. This one looks a little colder, with snow becoming a better bet across much of the region, though the South Coast and Cape Cod may see some rain. This system also looks to contain a little more moisture so there is the potential for a decent-sized storm, especially across the interior, but this is still nearly a week away, so things can and will change numerous times between now and then. We’ll have more details on this system in our Weekend Outlook on Thursday, but we wanted to give you plenty of heads up on this one, since a lot of people tend to travel to parties on Super Bowl Sunday.
