Scattered showers and storms will increase in coverage this afternoon limiting afternoon highs to the low 90s. Tropical moisture will make any storms that do develop capable of heavy downpours with ponding of water and potentially flooding possible should storms stall or move over the same area.
Dangerous heat makes it return by the second half of the weekend and into next week. Expect temperatures to rise into the low to mid 90s with max heat indices up to 109F by the middle of next week. Daily afternoon thunderstorms are possible as well.
The Climate Prediction Center has outlooked the Tennessee Valley in a Medium Risk (40-60%) for much above normal temperatures late next week. This means temperatures have a medium chance of reaching or exceeding the mid to upper 90s and heat indices between 100-105 degrees during this period. Stay weather aware and up to date with the forecast!
