With a light breeze from the south, temperatures did not cool off very much last night. We start the day with patchy fog along the south coast with a few showers and temperatures in the 50s to lower 60s.
A front working in from Canada and New York will generate showers by midday and then thunderstorms in the afternoon.
Ahead of the storms a few hours of sunshine should generate temperatures close to 80 degrees.
By 3 p.m., we likely have a line of thunderstorms from the Lakes region of New Hampshire into southern Vermont. This line will progress towards the south-east at 20 to 30 mph with gusty thunderstorms and downpours. Thunderstorms may create locally damaging wind, gusting past 55 miles per hour resulting in spotty tree damage and scattered power outages.
Any single thunderstorm should last only 15 to 20 minutes but rain may linger a bit during the evening in southern New England.
The sky remains mostly cloudy tonight and cooler — low in the 40s north and 50s south.
High pressure from southern Canada brings chilly air tomorrow, with clouds lingering across much of central and southern New England, high temperature mostly in the 50s.
The sun should come back on Thursday with temperatures warming back into the 70s.
Late in the week, we're tracking tropical energy from the Gulf of Mexico and Florida. That wet weather slides northward into New England with rain possibly arriving Friday, perhaps lingering into the weekend. We will work to try and improve that part of our ten-day forecast.
