Discussion
The latest model runs are in good agreement with the forecast. Another system will move across the racecourse Thursday and Friday bringing scattered, mainly afternoon thunderstorms to the area. Some storms could be strong with brief heavy rain and gusty winds. High pressure will build over the southeast U.S. on Saturday. This will limit thunderstorm activity and also start building the heat. Temperatures will climb into the lower 90s with Heat Index values rising into the mid and upper 90s during the afternoon.
