    What to Know

    • TUESDAY: Humid air fuels scattered showers and thunderstorms in Vermont and New Hampshire, later reaching Massachusetts.

    • TUESDAY AFTERNOON: Thunderstorms can be expected in central Massachusetts and across Connecticut.

    • LOOK OUT FOR: Heat advisory in Boston, flash flood watch in parts of New England, prolific lightning.

    Severe weather hit much of New England on Tuesday.

    Severe thunderstorm warnings were issued for several counties in Massachusetts, New Hampshire, Maine and Connecticut. Flash flood warnings were in Massachusetts, including the Greater Boston area, New Hampshire and Vermont. A severe thunderstorm watch was been issued across much of New England.

    A tornado warning was briefly issued for parts of northern Connecticut on Tuesday afternoon.

    These advisories have since expired, but there have been many reports of trees and wires down across Massachusetts, and heavy flooding was reported in Manchester, New Hampshire. Thousands lost power as a result of the storm.

    During the early morning, scattered showers and thunderstorms were in Vermont and New Hampshire, consolidating by late morning across southern New Hampshire into western Massachusetts.

    For the afternoon, we're looking at a line of thunderstorms along the Maine Turnpike down to central Massachusetts and across much of Connecticut, sweeping east to the coast by dinner time.


    Wind ahead of the front is from the south at 10 to 20 mph, but any thunderstorm can generate gusts in excess of 60 mph, with the locally damaging wind.

    Rain could briefly be torrential, and prolific lightning is likely. Flash flooding is also possible, with local 2-inch plus rainfall in less than one hour.

    The line of storms should be moving off the coast and out to sea by sunset.

    Then we have warm, but much less humid air, coming in for most of the rest of the week.

    High pressure from Canada brings sunshine and warm afternoons in mid-80s, and nighttime lows in the 50s to low 60s.

    The weekend should start off nice with sunshine, but humidity builds once again, and a front of may bring showers by Sunday.

    Early next week we may have a front stalled here in New England with tropical moisture streaming northward, with the chance of occasionally heavy rain for a couple of days, we could really use the rain, but that's still quite a way out.
