Summerlike warmth and humidity will continue through the rest of the week in the East, but locally heavy, gusty thunderstorms will also be in the picture.
The warm and humid weather has been gradually moving in since Memorial Day and will hold through the middle of the week.
In the warm and humid air mass, showers and thunderstorms will develop and will be more widespread than they were on Tuesday.
The storms will turn locally severe with damaging winds and blinding downpours from northern Virginia and western Maryland, northward to upstate New York, Maine and neighboring Canada.

Philadelphia, Baltimore, Washington, D.C., and even parts of the New York City area could be in the path of stronger storms on Wednesday afternoon. The threat for heavy, gusty storms will extend northward into Albany, New York, and Burlington, Vermont.
As a weak cool front slowly moves across the mid-Atlantic on Wednesday night into Thursday, it will continue to bring some showers and thunderstorms.
By Thursday, most of the thunderstorm activity will be focused from New England down along the I-95 corridor.

Behind the front, humidity levels will come down somewhat by later on Thursday and Friday. Even though the humidity will come down, temperatures will remain above average for this time of year.
Much of the time on Friday and Saturday will be dry, which will allow temperatures to surge into the 80s thanks to a southerly flow.

Not everyone will get into the warmth, though. A cooler, easterly flow of air will keep temperatures mostly in the 70s across eastern New England, Long Island and the Jersey Shore both days.
The easterly flow will pull air in off the Atlantic, which is still chilly even though things have been heating up over land.
"People planning a trip to the beach should use caution when venturing too far into the water, AccuWeather Senior Meteorologist Alex Sosnowski said. "Surf temperatures this time of the year range from the 50s along much of the New England coast to the 60s over the southern mid-Atlantic."
Thunderstorms will start to move back into the Northeast and mid-Atlantic late on Saturday into Sunday as a stronger cold front moves through.
That front will bring the extended round of summerlike weather to an end for a little while, with cooler and less humid air moving in for early next week.
