The high in Oak Ridge is forecast at 97 degrees on Thursday. The heat index is forecast to be a bit higher than that in the region. It is forecast at 99 degrees in Knoxville on Thursday and 100 in Kingston. The heat index includes the effect of humidity and measures how hot it will feel.
The forecast calls for an even higher heat index on Friday. Kingston is forecast to have a heat index of 105 on Friday, Knoxville will feel like 102 degrees, and Chattanooga could have a heat index of 106, the NWS said.
“Looks like a few more hot days ahead with heat indices exceeding the century mark in the southern valley,” the Weather Service said in a social media post. “As of now, Friday looks warmest, however there will be a front in the area during the afternoon, which could alter things.”
On Wednesday, the National Weather Service said it is hot today (Wednesday, July 28) and will be the rest of the week.
“Everyone needs to practice heat safety to remain healthy and safe from the hot weather,” the NWS said. “Stay hydrated and take frequent breaks in air-conditioned spaces if working outdoors. Heat deaths are preventable!”
