 The 7 News First Alert forecast from Steve Rudin. Sizzling temperatures continue for one final day, but I'm tracking a cold front. This cold front arrives here this afternoon and into the evening. It's triggering showers and thunderstorms. Some will have the potential to become strong to severe and may even contain some very heavy downpours. A flood watch until midnight for the D.C. metro area. Once we get the storminess out of here late tonight, our skies will partially clear. Partly sunny on your Thursday, 85 to 90 degrees.
