THE HEAT ADVISORY FOR MOST OF MIDDLE TENNESSEE HAS BEEN EXTENDED TO 7PM SUNDAY FOR HEAT INDEX VALUES AS HIGH AS 106.
The high temperature today on the thermometer should reach 98° like it did yesterday. With dew points in the low 70s, the heat index could be as high as 106°. If you have been working all week in the air conditioning and have outdoor plans, take breaks in the shade and drink plenty of water.
On Sunday, a front will approach from the north and increase our scattered thunderstorms chances by the afternoon and evening hours. However, temps should reach the mid 90s, with a heat index in the 104° range before those storms break out. A few of the thunderstorms Sunday afternoon and evening could have some gusty winds, frequent lightning, and cause localized flooding. The Storm Prediction Center has northeast corner of Middle TN in a “Marginal” risk for severe weather.
That front will go stationary nearby Monday and Tuesday keeping rain chances high and holding the thermometer down in the upper 80s then.
