Flash flooding possible amid scattered storms Monday night

Severe storms crossed the Baltimore region by 5 p.m., largely sparing the area of significant damage, but forecasters warned flash flooding remains possible through Monday night.

A flash flood watch remains in effect for Baltimore, Howard, Anne Arundel and Harford counties and Baltimore City through 9 p.m., according to the National Weather Service. Widespread rainfall of 1-2 inches is likely, and some areas could see as much as 3 or 4 inches as scattered storms continue into the evening.

The weather service reported 0.86 inches of rainfall at Baltimore-Washington International Thurgood Marshall Airport in the 4 o’clock hour.

Forecasters canceled a severe storm watch across the Baltimore region by about 5 p.m., after an initial line of storms crossed the area.

The line of storms prompted a tornado warning in the Lancaster and York areas of southern Pennsylvania about 1:45 p.m.

A cold front was producing storms along the Interstate 95 corridor from central Virginia into New England.

Temperatures reached 90 degrees in Baltimore by 3 p.m., with oppressive levels of humidity making it feel like the mid-90s. But temperatures dropped nearly 20 degrees as the storms passed, to 71 degrees by 5 p.m.

The storms capped a weekend of high humidity and steady heat. A new “record warm” low was set at Washington Dulles Airport on Sunday. The low of 73 degrees snapped the previous record of 71 degrees set in 2014.

Looking ahead, storms may resurface on the weekend. But Tuesday through Thursday present mostly sunny to partly cloudy skies, with temperatures ranging from the high 60s at night to the high 80s in the afternoons.
