Saturday night update: High pressure remains in control tonight, keeping skies clear and winds light across the CSRA. That setup allows temperatures to drop efficiently, though a subtle breeze just above the surface may keep things from getting too cold.
Expect overnight lows mainly in the low to mid-30s, which is right around (or slightly below) average for late December. A jacket will definitely be needed if you’re heading out late tonight or early Sunday morning.
Sunday marks the winter solstice, but the weather won’t feel particularly wintry during the afternoon…
