Widespread rain with embedded thunderstorms will overspread central Virginia tonight, ahead of an upper-level wave and associated surface cool front. Much of the area is well below normal in rainfall for the year, with the deficit now at 6.25" in Richmond. The downside to this rain event will be the flash flooding, which will likely occur in many areas. The rain should come through in several waves, with the last of the activity ending from west to east Thursday afternoon.
