DAYS 1-5 (MARCH 22-26)
Spring is here and the late March portion of it is a time when we have many weather mood swings typically, and some of what will be on display during this 5 day period, including this weekend. Today will feel more like mid spring with a shot of mild air. The daylight hours will be mainly dry as a strong cold front approaches from the west. It will be a breezy day taking a little bit away from the mildness of the air, but not too much. This front has little moisture to work with so only a brief passing rain shower favors areas north of I-90 this evening. A secondary trough may initiate a brief snow flurry in northern MA and/or southern NH overnight, leading a shot of colder air into the region, so our mild Saturday as followed by a chilly Sunday. A gusty wind will make high temps in the 40s feel more like 30s. Sunday night’s a cold one as clouds move in ahead of a low pressure area. This system will cross the region during Monday, and with enough cold air around it can and probably will start as snow over a portion of the region, especially north of I-90 and from I-95 westward, where some minor accumulation may occur before rain takes over. The storm departs Monday night, but cold air aloft means a lot of clouds can be around on Tuesday, but with no more than a passing light shower of rain/mix/snow, with a chilly breeze expected. The next low pressure system, small and fast-moving, brings another chance of unsettled weather to our region on Wednesday, but this one may scoot a little further south and be more of a side-swipe. I’ll follow the trends on that as we get closer to it.
