First Alert: Storms bring heavy rain and lightning across New England

We have a First Alert Monday as storms and showers are found all across New England. An upper-level low pressure system and a cool pool of air aloft will help get some severe weather going Monday. 

This fueled by the classic daytime heating as surface temps heat up to the low 80s with dewpoints in the mid-60s. Then, like popcorn, the storms develop rapidly at any time through sunset.

Damaging wind, large hail, lightning and localized flooding rainfall are the threats we face. Once the sun sets, the atmosphere stabilizes, and the storms fizzle out. Temperatures fall to the 50s or 60s Monday night with fog developing.

Flash flood warnings and severe thunderstorm warnings were in effect across New England for much of the day, but they have since expired.

Tuesday brings a break from the storms with sun and highs in the low 80s. Our temps and humidity will increase for Wednesday ahead of an area of low pressure moving in from the northwest.
