It still appears very likely that central Virginia will be influenced by a two-part storm system next Friday and Saturday. The first part will be a cold front arriving early Friday, dropping high temperatures from the mid 70s Thursday to the upper 50s on Friday. This cooler air will remain in the area through Saturday. The second part will be an upper storm system arriving from the southwest that will bring rain to the area Friday into early Saturday. There’s a chance that the rain could end before the race, but at this point in time, I’m keeping the forecast as is. I am lowering the temperature for race time, as there appears to be a consistent signal for colder air to move in on Friday. Here’s my latest forecast:
Mostly cloudy and cool, with a 40% chance of rain, and temperatures from 8 AM – 11 AM ranging from 42-47 degrees.
