A Heat Advisory covers most of the Tennessee Valley for Thursday and Friday afternoon and evening. Drink plenty of water and limit outdoor activity or take breaks if possible.

A late season heat wave will peak this week, with temperatures soaring well into the 90s for most locations. Heat indices will climb into the 100s. Heat is one of the leading weather-related killers in the US! Take hot temperatures seriously, drink plenty of water, find A/C, and remember to look before you lock when exiting vehicles.

A few strong to severe storms are possible on Friday afternoon and evening, mainly across northeast TN and southwest VA. The main threat is damaging winds.

Scattered storms are expected Saturday afternoon and evening. Some storms may bring strong to severe wind gusts and small hail.
