Maryland Weather Meteorology, astronomy and climate conditions in the Baltimore region

Flash flood watch in effect Friday night along Interstate 95 corridor

Slow-moving thunderstorms could create flash floods across the Baltimore region Friday night, the National Weather Service warned.

A flash flood watch is in effect through 11 p.m. along the Interstate 95 corridor, including in Baltimore, southern Baltimore County, and Howard and Anne Arundel counties.

Meteorologists warned that some storms could produce downpours lasting more than an hour. Rain could fall at rates exceeding 2 inches per hour, potentially leading to flash flooding — especially in urban areas, they warned.

The storms come as a cold front approaches the region and then stalls to the south, bringing rainy conditions throughout the weekend. More than 2 inches of rain are possible from Friday night through Sunday, with higher amounts in areas that see the heaviest downpours Friday.

The front is also expected to bring significantly cooler temperatures for the weekend.

Saturday’s warmest temperatures, in the lower 70s, are forecast in the early morning hours. Cooling is expected throughout the day, to the lower 60s by evening.

Highs are forecast around 70 degrees Sunday afternoon.
