Warm but more moisture-laden air will overspread the area tomorrow as a strong storm system and cold front approach from the west. During the afternoon, as a cold front approaches the Appalachians and an associated area of low pressure moves across eastern Ohio and western Pennsylvania, our area will be in prime position to see lines of strong to severe thunderstorms develop east of the mountains and then advance eastward towards the urban corridor and the Chesapeake Bay.
It is likely that some or all of our area will be placed under Severe Weather Watches and Warnings. Right now, it appears the Greater Washington area will see the highest probability of severe weather between 5 and Midnight. Strong winds and hail will be likely features of the stronger storms. Mid and upper level atmospheric dynamics will also support formation of isolated tornadoes.
