Here's another site with predicted windspeeds, gusts, rain, etc. Pretty much the same as Dan T. posted, but visually angrier looking. They both match up pretty well from what I've seen. If this holds up, it looks like Central VA is definitely getting soaked for the entire weekend once it starts, with gusts in the 30 MPH range. NOVA/DC gets off a little easier. Looks like gamestime Sunday up there, there will be maybe light precip and gusts up to around 15 MPH.
