We’ll be riding the temperature roller coaster for the first several days of March. I’m not a great fan of the lamb/lion saying for March, however the month did come in on the lamb side with a breezy but pleasant Tuesday, with lots of sunshine. But as you know, things have been moving along, and rapid weather changes will mark the next several days.
Synopsis…
Wednesday… A brief warmup takes places through early to mid afternoon along with a gusty southwest wind. A strong cold front sweeps across the region later in the afternoon & early at night, bringing the threat of a rain or snow shower, possibly a heavier squall of either rain or snow, or rain changing to snow, and a risk of thunder. This will usher in an arctic airmass later at night, when temperatures will plunge as will wind chills, with strong northwest winds.
Thursday… Bright but bitter. Pure arctic air will dominate as high pressure builds south southeast from Canada. Winds will be gusty to start the day but will settle down later.
Friday… Very cold early as the arctic high pressure slides east of the region. Clouds will advance as a warm front approaches from the southwest. This front may produce a period of snow at night.
Weekend… Much milder! Not totally sunny, but other than spotty precipitation very early Saturday and a chance of rain by late Sunday, the bulk of the weekend will be dry.
Forecast for Boston area…
TODAY: Partly sunny. A passing rain shower after 2PM. High 42 to 47. Wind southwest increasing to 15 to 25 mph with gusts over 30 mph.
TONIGHT: Partly cloudy with a passing rain or snow shower possible early, including a slight risk of briefly heavy precipitation with thunder, followed by clearing, windy, and much colder. Low 10 to 15. Wind shifting to northwest 15 to 25 mph with gusts over 30 mph. Wind chill near zero overnight.
THURSDAY: Sunny. High 20 to 25. Wind northwest 15 to 25 mph in the morning, diminishing in the afternoon.
THURSDAY NIGHT: Clear. Low 5 to 10 inland, 11 to 16 coast and urban centers. Wind light variable.
FRIDAY: Increasing clouds. High 30 to 35. Wind light southeast.
FRIDAY NIGHT: Cloudy with a period of snow. Low 25 to 30. Wind light east.
SATURDAY: Mostly cloudy with a chance of rain or snow showers in the morning. High in the 40s.
SUNDAY: Mostly cloudy with a chance of rain late in the day. High in the 50s.
I guess this could be the most impressive, short lived cold airmass of the whole entire winter with full early March sun and highs only in the low-mid 20s. Quite a cold high temp when tomorrow’s sun is equivalent to around October 10th. Its nice to have the daylight returning so quickly at both ends of the day.
I think Boston got to 28 or 29. I suspected they’d get a bit higher than guidance suggested. Nevertheless, nice cold airmass for March! I still don’t think we’re done. Last year, winter died early, this year it may have loosened grip but it has still got a few punches left to throw.
