Key Messages
- Heat Advisory is in effect Thursday and Friday for heat index values peaking between 106-110F. The advisory may need to be extended into the weekend.
- Rain chances will be very low through Friday, but might need to keep an eye out for some isolated-scattered activity near the Piney Woods Friday evening.
- No substantial changes to the weather pattern through most of next week...so the August heat continues will mainly dry conditions.
