A hot and humid week is expected with most places seeing heat index values near or above 100° by Wednesday. Rain chances do not return until late in the week.
Most areas will be dry for the next week or so. The best chance for any precipitation will be along the Smokies. Additionally, high pressure aloft will begin to strengthen over the region into this week, for a return of hot and muggy conditions. Heat indices will warm into the 100 to 105 range.
