 That's your best chance. So shower chances for evening plans will be diminishing. Partly sunny skies on Sunday, near 90 degrees. I'm 7 News Chief Meteorologist Veronica Johnson in the First Alert Weather Center. At Reston this evening, it's 83, Bethesda 83, National Mall 84. Gradually falling to even 60 degrees for our low in a few suburban areas. Overnight between D.C. and its suburbs, we're down between 60 and 70. Now 730 on WTOP.
