The good news is that the shower and storm activity with this cluster has been dissipating and shrinking somewhat as we have gone through the morning, and that trend shall continue. Estimates at this point for the activity to come to an end at the track is around 10 am - 11 am.
The latest runs of the high-resolution forecast models show that there will be some redevelopment of scattered showers and storms, but at this point, none of that activity looks to invade the racetrack until after 5 pm this evening. Of course, the forecast can change, and I'll have any radar updates on Twitter throughout the day as I will be at Barber for the race.
Sky Cover: Cloudy through morning, becoming partly cloudy during the afternoon.
Rain chances: 100% this morning, dropping to 30% through the afternoon.
Daytime high: 80F
