Boston stepped out the door this morning to clouds, scattered showers, and the chance of an isolated rumble of thunder. Temperatures started in the upper 60s to low 70s and are expected to climb to about 78°F this afternoon with a west wind near 10 mph. The good news for anyone tired of the wipers already working overtime: most of the rain should move out by mid-morning, with partly sunny skies taking over for the afternoon.
A Coastal Flood Statement remains in effect through Tuesday night as high astronomical tides pair up with a modest storm surge that could push water onto low-lying roads. According to the National Weather Service Boston/Norton, up to one foot of inundation is possible in vulnerable spots, which is enough to affect Morrissey Boulevard and other shoreline streets while leaving most major routes passable. Officials are sticking with the classic advice for days like this: do not drive through flooded roadways.
Morning Commute
Plan on wet pavement for the early commute, with brief heavy downpours or an isolated clap of thunder possible before mid-morning. Forecasters expect the bulk of the showers to clear out between about 7 and 9 AM, with visibility and road conditions improving through late morning. If your route hugs the waterfront, keep an eye out for splashover in the usual low spots.
Afternoon And Week Ahead
This afternoon should feel noticeably calmer, with a drier setup, highs near 78°F, and west winds around 10 mph. Tuesday looks sunnier and a bit cooler, but the quiet pattern does not last for long.
Later in the week turns more active as a stronger disturbance moves in, bringing a higher chance of showers and gusty south winds on Thursday, with gusts up to 30 mph possible, per the National Weather Service. Juneteenth on Friday looks breezy with only a slight chance for showers before fairer weather returns for the weekend.
Boaters And Shoreline Residents
Small craft should go easy through the southern waters early this morning, and shoreline residents will want to watch this evening and Tuesday high tides for nuisance splashover. If you live or park near the waterfront, moving vehicles off low-lying roads tonight is a smart move to avoid getting cut off by high tide.
