A day after hitting 60 in Taunton, 55 in Boston, and breaking the streak of 11 days in a row below average, we’re back to the colder weather with a bit of a breeze. It’s not a bad day overall though as highs edge into the mid to upper 30s and we can keep some sunshine out there.
Clouds do increase overnight, foreshadowing a few snow showers to come as the first chance for flakes arrives pre-dawn tomorrow. This is not a big storm by any stretch, but morning snow showers may drop a coating to an inch of snow for some, which is just enough to get the salters and sanders back out, and allow for a few slick spots early in the day. By late morning and afternoon, temps rise toward 40, so the slick spots are fairly quick to melt away.
Tuesday is one of those milder days we can occasionally sneak in here, despite a colder overall pattern, as highs head into the lower 50s.
The better opportunity for a more widespread, significant precipitation event comes in here Wednesday midday, through Thursday morning. At this point, it’s not so much the question of “will there be a storm?”, rather it’s more the question of “what’s the exact track?”.
It looks like the favored position of the low is along a front the cuts across southern New England and down into the Ohio Valley. As the wave of low pressure rides along it, it’ll grab some Gulf of Mexico moisture with it and bring it into the Northeast. Moisture won’t be lacking, but cold air might be. If the track indeed takes a path over the southern New England coastline, an east to southeast wind wins out and it’s a mainly rain event for eastern Mass Wednesday, including the city of Boston. As the low moves offshore, winds turn back to the north, and rain changes to snow overnight/early Thursday, allowing for some minor accumulations. Farther north and west, especially outside 495, we’d have a better chance to mix in with snow Wednesday and Wednesday night and change to all snow early Thursday AM, allowing for higher totals there.
If the low tracks south of New England and not over southern New England, it would mean colder air is in place and more snow for all. It’s too early to say for sure, or at least too far away to start drawing snow maps, but as of now, I’m leaning more toward the “milder” solution.
Bitter cold air does follow in Thursday night and Friday morning, before trending back toward average next weekend.
Have a great Sunday!
