DAYS 1-5 (FEBRUARY 11-15)
A dry weekend for our area. Today will be a gusty and cool day between eastern Canadian low pressure and a high pressure area to our southwest. The high pressure area will drift into the region tonight into Sunday, diminishing the wind, but as this happens a new storm system from the eastern Gulf of Mexico will track across the US Southeast and off the Mid Atlantic Coast by later Sunday, passing southeast of New England Monday. This system will skirt the region with a period of rain most likely across the South Coast region possibly briefly getting into the Boston-Providence corridor before the system starts to move away. Just as it does so, cold enough air may work in to change the last of the rain to mixed precipitation or snow on Outer Cape Cod, but too late for any significant snow accumulation. Behind this system it will turn a little colder, and a disturbance dropping southeastward out of eastern Canada and into the trough accompanying the storm may bring a few snow showers early Tuesday to our region, especially southern NH and eastern MA, before the rest of the day is fair. A disturbance approaching on Wednesday from the west and southwest brings back some clouds and maybe a bit of rain, as we go right back to mild weather as has been the case so often this 3rd year La Nina winter…
TODAY: Sun and passing clouds. Highs 36-43. Wind NW 10-20 MPH, higher gusts.
TONIGHT: Mostly clear. Lows 20-27. Wind NW 5-15 MPH.
SUNDAY: Sunshine followed by increasing clouds. Highs 45-52. Wind variable up to 10 MPH becoming SW.
SUNDAY NIGHT: Thickening clouds. Rain likely South Coast. Chance of rain up to South Shore. Lows 35-42. Wind SW up to 10 MPH early, shifting to E 5-15 MPH overnight.
MONDAY: Cloudy with a chance of rain favoring southern and southeastern areas in the morning, may end as snow over Outer Cape Cod, then some clearing possible during the afternoon especially in areas north and west of Boston. Highs 42-49. Wind NE 10-20 MPH except possibly stronger in coastal areas, shifting to NW.
MONDAY NIGHT: Variably cloudy. Snow showers possible pre-dawn southern NH and northeastern MA. Lows 25-32. Wind NW 5-15 MPH.
TUESDAY: Lots of clouds with possible snow showers favoring southeastern NH and eastern MA early, then mostly sunny. Highs 37-44. Wind NW 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 18-25, 11-18 in normal cold spots. Wind calm.
WEDNESDAY: Early sun, then lots of clouds. A touch of snow or sleet possible mainly west and north of Boston then a chance of rain showers. Highs 43-50. Wind calm early, then S up to 10 MPH.
DAYS 6-10 (FEBRUARY 16-20)
A quick blast of warmer air February 16 into February 17 but may be pinched off a bit by a low pressure center that tracks a little closer to New England than models indicate – meaning the leading edge of warmest air arrives not too long before the cold front that trails the low pressure area. This system will bring a period of rain and showers, maybe even thunder along its cold front, and a fair amount of wind especially in the warm sector and behind the cold front as it turns dry and colder for February 18. High pressure settles in for fair and more tranquil but chilly weather February 19 and then watching for a low pressure system to approach with a precipitation chance by the end of the period – obviously timing uncertain at 10 days out.
DAYS 11-15 (FEBRUARY 21-25)
One or two precipitation threats are possible in a fairly active pattern. Temperatures trend a little cooler but no major cold indicated at this point.
