 I'm 7 News Chief Meteorologist Veronica Johnson in the First Alert Weather Center. At the wharf in D.C., we're at 77. National Harbor Area, 76. Sterling, 76. Some parts of our area could fall to about 70 overnight. It's 9.30 here on WTOP. You're listening to WTOP, Washington's news, traffic, and weather station. The WTOP producer's desk is wired by IBEW Local 26, where electrical contractors come to grow.
