A strong area of low pressure over the Great Lakes slowly tracked to our north on the 8th. The cold front associated with the low moved into the region during the afternoon and evening hours. A moist southerly flow ahead of the front provided instability. The instability combined with the forcing from the front to trigger showers and thunderstorms during the afternoon and evening hours of the 8th. Due to strong winds aloft, some thunderstorms produced gusty winds over the Tidal Potomac and Chesapeake Bay.
