An approaching cold front will trigger showers and thunderstorms on Tuesday in the Northeastern United States. Clouds will thicken overnight, and rain is possible by dawn in western CT and MA. The rain will spread east during the morning, and part of the commute could be affected in RI and SE MA. The day will begin with temperatures in the mid 60s.
The heavy shower and thunderstorm threat is greatest from mid-morning through mid-afternoon as the first of two disturbances passes. There may be a break in the action late in the afternoon before a cold front arrives with scattered showers and thunderstorms in the evening. It will be a mostly cloudy and muggy day when it is not raining. Highs will be in the low to mid 70s.
Gorgeous mid to late workweek
The cold front will move offshore Tuesday night, and dry, pleasant weather will rush into New England from Canada. Wednesday looks partly to mostly sunny, breezy, and dry. Highs will be in the mid 70s. The dew point will drop into the 40s to low 50s by late in the day. A northwest breeze will average 10-20 mph, with a few higher gusts.
It will be clear and comfortably cool Wednesday night. The low temperature near dawn Thursday will be in the low to mid 50s. Thursday afternoon looks spectacular, with mostly sunny skies and highs in the mid 70s. Friday should be an encore performance as it stays mainly clear, dry, and pleasant.
Looking ahead to the weekend, there may be a few more clouds on Saturday, and mostly cloudy skies by Sunday as a disturbance in the Southeast slowly creeps north into the Mid-Atlantic. At this point, it does not seem that there will be any rain this weekend. The humidity levels will inch up a bit, but it does not look oppressively humid. Highs will be in the low 80s inland, and 70s near the coast with an onshore breeze.
