DAYS 1-5 (FEBRUARY 9-13)
Late update today so quick and to the point. A weakening system approaches today and may cause a touch of light snow mostly west and north of Boston, but city flakes can’t be ruled out either. Then a low pressure area will fly down the St. Lawrence Valley then cut across northern Maine Monday, and its warm front will bring some rain and snow to the region Monday morning followed by its cold front and a few rain showers Monday afternoon. This cold front comes to a halt just after passing by and a wave of low pressure will run along it. It’s a close call whether this passes just too far south or close enough to bring its precipitation shield into southeastern New England, but right now I’m leaning toward the “bring it in” scenario, although the air should be mild enough for rain, and not snow. That departs and we get a high pressure area bringing slightly colder air in for Wednesday, setting the stage for the next low to come along Thursday, with marginal temperatures, and the precipitation type question to be answered as we get closer to the event.
TODAY: Variably cloudy. Risk of a touch of light snow. Highs 33-40. Wind variable up to 10 MPH.
TONIGHT: Mostly cloudy. Remote risk of a touch of light snow south of Boston evening. Lows 23-30. Wind variable under 10 MPH.
MONDAY: Mostly cloudy. Risk of a period of snow/sleet interior, rain coast early, then rain tapering off from west to east in the morning. A few rain showers possible from northwest to southeast in the afternoon. Highs 38-45. Wind S up to 10 MPH early, SW 5-15 MPH gusting to 20 MPH mid morning into afternoon, shifting to NW later.
MONDAY NIGHT: Mostly cloudy. Lows 30-37. Wind NW 5-15 MPH.
TUESDAY: Cloudy. Chance of rain southern NH and northern MA. Rain likely elsewhere. Highs 38-45. Wind variable to N up to 10 MPH.
TUESDAY NIGHT: Clearing. Lows 20-27. Wind NW 5-15 MPH.
WEDNESDAY: Sun and high clouds. Highs 35-42. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Clouding over. Lows 20-27. Wind NE up to 10 MPH.

One or two more opportunities here for messy winter weather but far too early for details.
