Repeat after me: Please no rain, please no rain, please no rain, please no rain, please no rain...
The Saturday forecast:
8am: Cloudy, Rain possible...50s
11am:Mostly Cloudy...lower 60s
A front will be crossing Virginia Saturday morning with showers and a possible thunderstorm early in the morning. The timing could work in favor of the runners, as most of the rain could be over by 8am, depending on the front's progress. Keep in mind, if the front slows down, rain chances will stick around longer. Temperatures will be warmer than average, with mid 50s early and lower 60s closer to noon.
