DAYS 1-5 (MARCH 21-25)
Much like last weekend, in comes some Canadian chill, a breezy Saturday, and a more tranquil Sunday as the cold air becomes established from high pressure that takes up residence in southeastern Canada. This high is going to play a role in our next unsettled weather event as well, which will arrive Monday and peak Monday night as low pressure moves off the Mid Atlantic Coast and passes south of New England. This set-up is one that will allow snow to occur in a fairly significant portion of the region for at least several hours, resulting in accumulation, with the greatest threat of this being away from the coastal areas. Eventually warm enough air should be able to change things to rain for most locations before it all ends. I’m not convinced that the entire region changes to rain, however, and that and other little details will still be worked out over the next 2 days leading up to the event. But wait there’s more. There was a suggestion the other day that a follow-up storm would occur around Wednesday, and this looks to be the case. It may take a very similar track but with a slightly milder atmosphere, so the rain/snow ratio would be tipped more in favor of the rain, however at day 5 there are still questions to be answered with that system as well.
TODAY: Limited sun into late morning southeastern MA and RI, otherwise mostly sunny. Highs 45-52. Wind NW 15-25 MPH.
TONIGHT: Clear. Lows 28-35. Wind NW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 38-45. Wind N 5-15 MPH.
SUNDAY NIGHT: Clear. Lows 28-35. Wind NE under 10 MPH.
MONDAY: Increasing cloudiness. Highs 38-45. Wind NE up to 10 MPH.
MONDAY NIGHT: Overcast. Snow/mix develops early then changes to rain but may remain snow/mix for longer away from coastal locations. Preliminary snowfall accumulation expectation: Coating-2 inches southeast of the I-95 belt, 2-4 inches I-95 belt and I-495 belt south of I-90, 4-6 inches I-495 belt north of I-90. Lows 28-35 evening, may rise slowly overnight. Wind NE 10-20 MPH.
TUESDAY: Cloudy start with mix/rain/drizzle/fog possible early, then breaking clouds. Highs 40-47. Wind N 5-15 MPH.
TUESDAY NIGHT: Cloudy. Lows 30-37. Wind NE up to 10 MPH.
WEDNESDAY: Overcast. Rain likely, except some mix/snow possible interior areas. Highs 35-42. Wind NE 10-20 MPH.
DAYS 6-10 (MARCH 26-30)
A weaker storm system comes through later March 26 and March 27, a milder set-up with rain showers being the likely result. Another low pressure system brings the threat of rain/mix to the region sometime during the March 28-29 weekend. Drier weather arrives late in the period.
DAYS 11-15 (MARCH 31-APRIL 4)
Dry final day of March, unsettled start to April is the current indication.
