 A hit or miss shower or storm may fire off to the west, but into the evening, a better shot for a few scattered thunderstorms as a boundary pushes through. 70s overnight. Tomorrow, low 90s. Should be a little less intense with humidity. I'm 70s meteorologist Brian Van de Graaff in the First Alert Weather Center. We are at 79 in Manassas, 80 in Frederick, 82 at Metro Center.
