Rain chances this weekend

If you are heading to the Army Parade Saturday afternoon, take a poncho or umbrella. Storms could affect the festivities along the National Mall. We've got more information on that here.

A cold front will head South through our area Saturday afternoon and settle just to our South on Sunday. With the front close by and a steady east wind coming in from the ocean, Sunday and Monday will be quite a bit cooler. Highs will stay in the 70s both of those days with frequent periods of rain. Most of our area will get between 1.5” and 2.5” of rain between this afternoon and Tuesday morning.
