Dangerous heat expected through the weekend with triple digit heat indices west of the Cumberland Plateau. Low to medium thunderstorm chances primarily east of Interstate sixty-five each afternoon and evening through Thursday. Stronger storms will be capable of damaging winds and heavy rain. Drier and even hotter conditions favored Friday through the weekend followed by some minor relief early next week. High pressure building in! Northwest flow tracking down! High pressure building across the southeast state, Middle Tennessee sitting in a boiling fate. Mid-nineties in the afternoon, atmosphere loaded, Convective available potential energy exploded! Downdraft potential energy locked on the scope, Tracking down southeast with zero room for hope. East of Interstate sixty-five, watch the radar blow, Damaging winds and heavy rain ready to show! Convection allowing models firing on the screen! Hottest weekend temperatures you have ever seen! One hundred five to one hundred ten degrees! Begging for a thunderstorm, begging for a breeze! TRIPLE DIGITS WEST OF THE PLATEAU! HIGH PRESSURE BURNING EVERYWHERE WE GO! EIGHTY PERCENT IN NASHVILLE ON SATURDAY NIGHT! NINETY PERCENT SUNDAY UNDER SCORCHING LIGHT! Thursday coming in with low thunderstorm odds, Fifteen to thirty percent mercy from the gods. Under the influence of the ridge sitting overhead, Heat risk extreme, every living thing dead. Overnight temperatures only mid-seventies, No recovery coming in the nighttime breeze! HEAT! Major to extreme risk for everyone! No escape from the midday sun! Limit your time outdoors today! The heat wave will not wash away! No relief until Tuesday comes... Ninety percent in Nashville... Under the high... It never ends!

SHORT TERM
(Rest of today through Thursday) Issued at 1117 AM CDT Wed Aug 12 2026
High pressure continues to build across the southeast US, but Middle TN remains in northwest flow.
Hot & humid conditions persist with high temperatures this afternoon expected to reach into the mid-90s west of the Plateau with heat indices in the triple digits.
With plenty of instability, DCAPE, and moisture available, the door is still open for another MCS to move through this afternoon or into the evening hours.
Radar trends this morning have been showing activity developing to the north and tracking southeast, and CAMs are still showing the potential for some storms to impact areas east of I-65. As with yesterday, any storms that do develop will have the potential for produce strong to damaging winds as well as heavy rain.
Any activity should diminish late this evening or overnight.
On Thursday, the high pressure builds a little more north which helps to lower thunderstorm chances.
They won't be completely zero, but low chances (15-30%) will persist still mainly east of I-65. Otherwise, under more influence of the high, temperatures will only warm further with highs reaching into the mid and upper-90s and heat indices of 105 to 110 degrees.
LONG TERM
(Thursday Night through next Wednesday) Issued at 1117 AM CDT Wed Aug 12 2026
The high builds more overhead Friday and into the weekend which should lend itself to a dry weekend.
But that does mean our hottest temperatures of this heat wave are anticipated for the weekend.
Many locations will be near the 100-degree mark Friday, and probabilities are high that several will get there Saturday and/or Sunday.
NBM probabilities west of the Plateau for at least 100 Saturday is 40- 70% (80% at Nashville) with Sunday probabilities up to 60-80% (90% at Nashville).
These temperatures, heat index values of 105-110+, and overnight temperatures in the mid to upper-70s will make for major to extreme heat risk for all.
Be sure to take care of yourself by limiting your time outdoors and staying hydrated.
Take care of others as well by checking in on those who are more vulnerable to heat.
These hot temperatures look to persist into Monday, but the heat wave will finally break come Tuesday as the high moves off the west and a front comes down from the south.
This pattern change will also increase rain and thunderstorm chances yet again early next week.
