Recent Severe Weather and Forecast Trends in the DC Region
Monday’s severe weather followed a pattern of thunderstorms moving through the region, with previous alerts issued earlier in the day.

Cooler, drier conditions are forecast for Tuesday, with the potential for scattered showers later in the week as humidity levels rise again.
