While the mid-Atlantic remains humid, more comfortable air has graced much of the Northeast this Sunday.
Gone Sunday is the 90-degree heat and high humidity that has been soaring northward to Portland and Bangor, Maine, recently.
In its place, high pressure will usher in cooler and less humid air following locally severe thunderstorms on Saturday.
The nicest conditions on Sunday will grace upstate New York and New England, where humidity will be at its lowest and temperatures will be held to the 70s and 80s.
Partly to mostly sunny skies and dry weather will compliment the day in both Portland and Boston. AccuWeather.com RealFeel® temperatures will be held to the lower 80s in both of these cities, a stark contrast to the recent triple-digit RealFeel temperatures.

A shower or thunderstorm will rattle New York City for a time Sunday, but humidity will be noticeably lower and temperatures will be more seasonable than what was recorded during the seven-day heat wave.

The steamy air will set the stage for a shower or thunderstorm to develop and briefly interfere with outdoor plans.
