Tonight & The Week Ahead

747PM

After a week of up and down temperatures (a mild start, a cold middle – upper 20s Thursday, and a mild end – 50s-lower 60s this weekend), what is in store for tonight & the coming week? Read on to find out!

TONIGHT: Steadiest rain falling well outside Route 495 at this time will slowly move eastward into the Boston area, but the heaviest will not likely occur in the Boston Metro area until after midnight. Only scattered showers are expected in the Boston area during the next several hours, though a few of them may be briefly moderate to heavy. Thunder is possible during the overnight hours. It will slowly cool from the lower 50s to the upper & middle 40s throughout eastern MA & southern NH. Winds will blow from the southeast to south up to 15 mph though some higher gusts are possible in coastal areas.

The Week Ahead…

Low pressure will cross the area from southwest to northeast during Monday morning with one final burst of rain and possible thunder early. As it moves away, wrap-around moisture will hold clouds in for much of the day along with scattered rain showers changing to showers of sleet & snow as colder air works in. Even though far western and especially northern New England will see major snow accumulation out of this system tonight & early Monday, I don’t expect any accumulation of sleet or snow in the Boston area, other than a short-lived dusting of snow in a few locations. It will simply be too late to get enough precipitation once the cold air is in place.

High pressure building eastward will result in dry but chilly weather Monday night through Wednesday. The next storm system will approach on Thursday, but some signs suggest the onset of this system may be very slow and not occur til Thursday night or Friday. Odds favor rain from this system at this time. Looking into next weekend, it looks cool and possibly unsettled. We’ll have to see how a few areas of energy heading through the Great Lakes & Northeast interact with each other.

Detailed forecast…

Mostly cloudy for the remainder of the day with scattered rain showers, changing to showers of sleet & snow from west to east during the afternoon. Little or no accumulation of sleet & snow expected.
