Updated at 109 AM EDT Thu Sep 17 2026- Above normal temperatures persist through the forecast period. Slight cooling into next week.
- Most areas will remain dry this week, however, increasing chances of showers each day in the higher terrain as we approach the weekend. A few valley locations in northeastern TN into VA may also see a shower or storm starting tomorrow, but more low to medium chances Friday into the weekend.
