TOM's Forecast Discussion:
High pressure will build over the area through Memorial Day Weekend. Hot and Humid conditions are expected through the weekend and Tuesday. It will be very steamy! The Heat Index will be over 90 degrees. A late afternoon shower/t-shower cannot be ruled out through the holiday weekend. Favored locations will be north and west of DC, especially over the mountains. Overall this Memorial Day weekend will be nice... just Hot!
