DAYS 1-5 (FEBRUARY 13-17)
A pretty potent low pressure area is passing southeast of New England early today but is far enough out to sea that it barely got its rain area over the South Coast, and that exists via Cape Cod this morning, leaving the region with a dry but breezy and cool day as clouds try to hang on through the day. Upper level low pressure scoots southeastward across the area tonight and very early Tuesday with a few snow showers mainly in NH and eastern MA. The balance of Tuesday, Valentine’s Day, will be nice but on the breezy side. A small area of high pressure crosses the region Tuesday night allowing the wind to drop off, but the wind picks right back up Wednesday as the high moves offshore and a disturbance moves in with clouds and a rain shower threat. This warm up continues through Thursday but additional wet weather arrives later as low pressure heads northeastward through the eastern Great Lakes. The low will then move down the St. Lawrence Valley Friday, dragging a cold front across the region with more wet weather, and putting an end to the warm-up. The timing of the front will help determine the high temperatures for Friday. My early idea is a midday frontal passage, a very mild and wet morning, and a colder and drier afternoon with plenty of wind.
TODAY: Lots of clouds. Early rain Cape Cod. Highs 41-48. Wind NE-N 10-20 MPH, higher gusts especially coastal areas.
TONIGHT: Mostly cloudy. Snow showers possible southern NH and northeastern MA with spotty minor accumulations. Lows 25-32. Wind NW 5-15 MPH.
TUESDAY: Sun and passing clouds. Highs 40-47. Wind NW 5-15 MPH, higher gusts.
TUESDAY NIGHT: Mostly clear. Lows 20-27. Wind NW up to 10 MPH becoming variable under 10 MPH.
WEDNESDAY: Early sun, then lots of clouds with a chance of rain showers. Highs 50-57 by late. Wind calm early, then SW 5-15 MPH with higher gusts.
WEDNESDAY NIGHT: Lots of clouds. Chance of a rain shower. Lows 43-50. Wind SW 5-15 MPH, gusty.
THURSDAY: Mostly cloudy. Chance of rain by late-day. Highs 58-65, possibly cooler South Coast. Wind SW 10-20 MPH, higher gusts.
THURSDAY NIGHT: Cloudy. Periods of rain. Lows 48-55. Wind SW 10-20 MPH.
FRIDAY: Cloudy with rain showers likely through midday, then a sun/cloud mix. Highs 55-62 morning, falling temperature afternoon. Wind SW 10-20 MPH with higher gusts shifting to NW.
DAYS 6-10 (FEBRUARY 18-22)
Dry weather expected over the February 18-19 weekend with a gusty breeze and chilly air Saturday, less wind and a little milder Sunday. Minor system may scoot through with a bit of precipitation February 20 and watching a larger low pressure system with a precipitation threat by the end of the period.
DAYS 11-15 (FEBRUARY 23-27)
Flatter ridge of high pressure in the US Southeast allows the boundary between warm air to the south and cold air in Canada to be in our region with a more unsettled pattern as a result. Many details to work out in the days ahead…
