That southern front pushed just far enough offshore that Southern new England should be mostly rain free today. However it is a very humid air mass and the dense fog near the coast may not burn off in some coastal locations.
If you’re looking for sunshine at the beach try and find something a little bit more north facing like the north side of Cape Cod or toward Cape Ann.

With a brighter sky today, high temperatures are pushing 90 degrees in many spots, and it is the beginning of several days of 90+ degree weather, the first heat wave of 2021.
Another front near the Canadian border is going to generate a round of powerful thunderstorms late today and overnight. There is a chance for isolated damage, and even a slight chance for a tornado near the Canadian border late today. That front will stall across central and northern New England tonight and tomorrow to continue the threat for some thunderstorms tonight and tomorrow afternoon.
But once again most of Southern New England should be rain free, and there’s a better chance the fog burns off at the shore tomorrow as the wind will have a little bit more of a westerly component.
Weather
Wind today is out of the southwest at 15 to 20 miles an hour near the coast, tomorrow more out more from the west at 10 to 20 mph.
This heat wave probably peaks Monday with temperatures well into the 90s, challenging records of 95 to 100° set back in 1925 and 1999.
By Tuesday and Wednesday another front from Canada is getting close enough for scattered afternoon thunderstorms and temperatures just a little bit less intense. But a heat advisory is likely for much of New England beginning either tomorrow or Monday, and the heat wave may not break until Wednesday or Thursday, as seen in our First Alert 10-day forecast.
