 This is the evening. I'm 7 News Chief Meteorologist Veronica Johnson in the First Alert Weather Center. At the wharf in D.C. it's 75, National Harbor 74, Stirling at 70 degrees. Some of us could be down to the 60s or even 58 for an overnight low. Now 931. 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.
