Winds will be light out of the south around two to five miles per hour. Clouds will increase a bit on Monday along with a chance for showers south and west of D.C. by late afternoon. The best chance for widespread showers will be Monday night into Tuesday when a few rumbles of thunder cannot be ruled out.
