ABC7's Chris Naille tells you what to do when faced with a tornado warning.

Scattered showers have developed this morning as warm front lifts to the north. A few thunderstorms may pop during the midday hours.

With warm and moist air overspreading the area, a strong storm system and cold front approach from the west.  The mid-Atlantic 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. Right now, it appears the Greater Washington area will see the highest probability of severe weather between 6 this evening and Midnight. Strong winds and hail will be likely features of the stronger storms along with periods of heavy rain. Flash flooding may be an issue later this afternoon and into the evening hours. Mid and upper level atmospheric dynamics will also support formation of isolated tornadoes.

A tornado watch has been issued by the National Weather Service for the entire D.C. metro area through 9 p.m. Friday.

Conditions will improve greatly by Saturday morning with afternoon highs in the middle 70s. Skies will be mostly to partly sunny.
