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.

A couple of systems will move across the racecourse this week. The first will move across the area Monday and Tuesday bringing numerous showers and thunderstorms, some with brief heavy rain. The next system will bring another chance of thunderstorms Thursday and Friday. This system will weaken, however the associated surface boundary will linger in the area. This will be the focus of afternoon thunderstorms on Saturday.

Potential Hazards
Friday…Scattered afternoon thunderstorms, Afternoon Heat Index 95-100

General Discussion
The week starts off a active with widespread showers and thunderstorms across Dauset. A large ridge of high pressure will build over the southeast U.S. for the last half of this week. This will bring a more summer-time pattern with scattered afternoon and evening thunderstorms. This will also bring higher temperatures and higher humidities which will put the afternoon Heat Index in the 95 to 100 degree range Friday and Saturday.
