DAYS 1-5 (FEBRUARY 12-16)
High pressure brings fair, more seasonably chilly weather today. Low pressure charges into the region Thursday, and like many systems this winter, the cold air that’s around to start will not be held in, so a snow to rain situation will occur, with minor snow accumulation away from the South Coast mostly occurring before dawn Thursday. One thing we have not seen much of this winter is very cold air, but we will get a taste of that for 2 days behind the departing storm, only to see a quick rebound by Sunday ahead of an approaching frontal system, which may bring a few snow showers to the region.
TODAY: Patchy clouds southeastern MA and RI early, sunshine dominant, but increasing high clouds later. Highs 35-42. Wind N up to 15 MPH.
TONIGHT: Clouding over. Snow arriving overnight, immediately changing to rain South Coast, then the rain/snow line progressing northward across the region through dawn after snow accumulations of a coating to 1 inch in the I-95 belt and 1-3 inches outside of I-495. Lows 23-30 evening, rising into the 30s overnight. Wind E 5-15 MPH.
THURSDAY: Overcast with rain except pockets of sleet north and west of Boston, ending late-day. Highs 36-43. Wind E-SE 5-15 MPH, few higher gusts especially coastal areas.
THURSDAY NIGHT: Clearing. Rapid freeze-up of any standing water / wet surfaces. Lows 13-20. Wind NW 5-15 MPH, higher gusts.
FRIDAY: Mostly sunny. Highs 23-30. Wind NW 10-20 MPH, higher gusts. Wind chill near 10 at times.

DAYS 6-10 (FEBRUARY 17-21)
Fair weather starts the period and returns late in the period, around a low pressure area which will impact the region during the February 18-19 time frame. The track of this system, and resultant impacts, are uncertain at this time. Overall temperatures near to above normal.
DAYS 11-15 (FEBRUARY 22-26)
Very low confidence but still watching for possible storminess sometime this period. Mixed signals in guidance and the large scale pattern drivers have been so persistent its hard to argue against them. Will monitor.
