 Eventually, the storm chances will watch this afternoon. Some of those may be strong with some gusty winds, but the best chance for any stronger thunderstorms likely west of the D.C. area. Potentially, they try to move in about 5 or 6 p.m., and they should dissipate just in time for the sunset hour, as well as firework shows late tonight. The weekend, it's still hot and humid. Highs in the 90s. Heat index as high as 100.
