Separate rounds of scattered thunderstorms will target parts of the Northeast on Thursday, July 9, and Friday, July 10, as humid air remains locked in place, according to the National Weather Service.
Most of Thursday will be dry for many areas, but warm, muggy conditions will help trigger isolated to scattered storms during the afternoon and evening.
The highest risk on Thursday is expected farther south, especially from New Jersey and Pennsylvania into Maryland and Virginia.
AccuWeather’s Thursday storm map shows the zone most likely to see stronger storms stretching across the Mid-Atlantic, with localized downpours, flash flooding, and damaging wind gusts possible.
AccuWeather says storms in that zone could produce localized damaging wind gusts of 55 to 65 mph, with isolated gusts up to 80 mph.
Friday brings a broader concern.
A more organized system is expected to move through by the afternoon, bringing heavier and more widespread thunderstorms.
The greatest risk for localized flash flooding will be in parts of Pennsylvania, New Jersey, and New York, where downpours could fall at rates of 1 to 2 inches per hour.
AccuWeather’s Friday map places the storm zone along and near the I-95 corridor, including areas from Richmond and Washington, DC, to Trenton, Atlantic City, and New York.
The main threats will be flash flooding and localized damaging wind gusts of 55 to 65 mph, with an isolated 75 mph storm gust possible.
The five-day regional forecast starts with partly sunny, humid weather Thursday, with seasonable temperatures and afternoon storm chances.
Friday will be mostly cloudy, with heavier storms developing during the afternoon. Highs will be in the 80s.
Saturday, July 11, will start with lingering clouds and isolated showers, then become drier in the evening. Highs will range from the upper 70s in New England to the low 80s farther south.
Sunday, July 12, will be sunnier and less humid, with highs generally in the low to mid-80s.
Monday, July 13, will stay mostly sunny and dry, with temperatures holding in the low to mid-80s.
