FIRST ALERT: Strong, Damaging Storms Possible During 90 Degree Heat Wednesday

Combined with temperatures nearing 90 degrees, Wednesday afternoon will feel somewhat sultry, setting the stage for strong or damaging thunderstorms

Following our Tuesday afternoon beauty, there should be a fantastic full "flower moon" rising in the east at about the same time the sun goes down in the west, just after 8 p.m.

Temperatures may require a light jacket with wind from the southwest gusting past 25 mph, and temperatures falling quickly from the 70s through the 60s into the 50s by morning.

The full moon is just past 7 a.m. tomorrow morning, and 'only' 222,117.21 miles from earth, the closest of 2021.

There is a lunar eclipse on the west coast Wednesday morning. If you are up very early, you may see the moon, glowing a little red, on the edge of the eclipse just as it sets in the west.

The continued southwest wind has a few other implications, as well: increasing atmospheric moisture will mean pockets of fog developing by Wednesday morning near the south coast, pockets of low-altitude clouds that will be stubborn near the south coast and particularly on Cape Cod Wednesday and an increasingly humid feeling in the air for most of New England.

Combined with temperatures nearing 90 degrees, Wednesday afternoon will feel somewhat sultry. It sets the stage for possible strong or damaging thunderstorms from northwest to southeast across New England late day and evening, with the greatest potential for frequent lightning and locally damaging wind gusts found in central and southern New England Wednesday evening as a cold front approaches from the northwest.

Our Team has issued a First Alert for Wednesday evening to raise awareness of the potential for some damaging storms in New England. The passage of the cold front Wednesday night into Thursday opens the door to less humid air and cools New England from hot to warm Thursday…with even cooler air arriving Thursday night into Friday. 

An approaching storm center forecast to pass south of New England will ensure noticeably cooler weather Friday, delivering a cool rain across at least southern New England. Just how much rain remains uncertain, as it depends on how close the storm center comes.

The storm track is really important in the Memorial Day forecast, too, because a series of additional storm centers will follow the path of the first. That means - at best - a series of days with cool onshore wind flow, variable clouds and a few scattered showers will follow for Saturday, Sunday and Memorial Day (that’s our forecast). But at worst, we’ll see periods of cool rain all the way through (less likely, not our forecast, but not impossible). 

For now, our First Alert Team follows a somewhat optimistic route of delivering some rain Friday into Saturday morning, then only scattered afternoon showers that may pop up Sunday in a few communities. We'll likely have a dry Memorial Day, but we’ll be keeping you posted, of course. The end of our exclusive First Alert 10-day forecast returns temperatures to near 80 degrees.
