Storms, humidity to return to Northeast by week’s end
Following a string of dry days in the middle of the week, stormy weather will return to the northeastern United States into Friday.
At midweek, enough dry air from Canada spilled southward to relieve areas in the mid-Atlantic that were clobbered by rain and stuck under clouds on Tuesday. Wednesday was the warmest day in nearly two weeks for a large portion of the region.
"Humidity levels will remain high in the lower part of the atmosphere over much of the mid-Atlantic at midweek and will climb later in the week," according to AccuWeather Senior Meteorologist Alex Sosnowski.

A storm will approach from the Midwest into Thursday night.
“Portions of the interior Northeast could see more concentrated showers and thunderstorms as early as Thursday afternoon and possibly as far east as Baltimore and Washington, D.C., but the rest of the I-95 cities should stay dry until Friday,” said AccuWeather Meteorologist Ryan Adamson.
"Due to the amount of moisture available to the storm, there is the potential for torrential downpours and isolated flooding," according to AccuWeather Chief Meteorologist Elliot Abrams.
Parts of the central Appalachians may experience flash flooding Thursday night.

Areas of rain and thunderstorms will dampen much of the region on Friday.
"Some of the storms in the mid-Atlantic region could be locally severe and the risk of localized flooding will continue on Friday," Abrams said.
This unsettled weather will likely spoil the beginning of the last weekend before some schools are back in session, especially along the New England coast.
Warm, sticky humidity will hang around through Saturday for many in New England, though the mid-Atlantic will have increasingly dry and bright weather later throughout the day.
“Temperatures will not drop too much behind the storm, but humidity will be somewhat lower,” Adamson said.
Sunday is expected to be a dry for most areas, meaning it will likely host a weekend’s worth of plans for those itching to spend time outdoors.
A generally active pattern is in store for the last couple weeks of August in the Northeast, so residents should make an effort to enjoy every last ray of sunshine.
