The middle of the week will be the period to watch. Showers and thunderstorms are possible Tuesday through Thursday, with the potential for locally heavy rain and some strong storms. Damaging winds and hail would be the primary concerns, while an isolated tornado cannot be ruled out. The exact timing and severity remain uncertain, but the potential for impacts is high enough to monitor as the forecast becomes more certain. Boating conditions will be poor for the middle of the week.

The trend is encouraging for Labor Day Weekend, with a return to mostly sunny and seasonable weather expected by Friday and Saturday. Severe weather should move out after Thursday and the humidity will be lower for the end of the week and the holiday weekend. However, there is still plenty of time for changes, so check back for updates.
