A Heat Advisory is in effect for all counties through Friday night. Major to extreme heat risk this week with heat index values in the triple digits. Wednesday and Thursday are expected to be the hottest days of the week. Low rain chances return this weekend into early next week. Middle Tennessee! Locked under the dome! Satellite imagery showing the crown, High pressure centered and holding us down! Upper nineties west of the plateau today, Nashville at ninety-nine, no way to pay! Tying the record from back in the past, How long can this atmosphere hold and last? Forty to fifty percent on the grid, Look at the pressure and look what it did! National Blend of Models calling the hit, We are trapped in the center of it! Triple digit index heavy and tight, No cool breeze coming into the night! The dome is not moving, the sky is ablaze! We are trapped in the middle of record-high days! No relief in the air, no cloud in our sight, We are locked in this chamber until Friday night! Thursday comes in with the exact same teeth, Ninety-nine, one hundred, no shade underneath! All counties covered under one single threat, Drowning in heat risk, soaked in our sweat! Forty to fifty percent chance we break, How much more can the city take? ONE HUNDRED! Major risk! Extreme risk! Centered over Middle Tennessee! Break the record! Break it! Low rain chances weekend bound, But right now we burn to the ground! Locked in heat! Locked in tight! Until Friday night!

- Low rain chances return this weekend into early next week.
SHORT TERM
(Tonight through Thursday Night) Issued at 1019 PM CDT Tue Sep 1 2026
Satellite imagery reveals strong high pressure that is essentially centered over Middle TN, and this will be the dominant feature for the next several days.
Hot temperatures from Tuesday will only get hotter with highs on Wednesday reaching into the upper-90s for areas west of the Plateau.
Nashville's forecast high is 99 degrees which is the record high for the date.
So there's a high chance that Nashville at least ties it. As far as outright breaking it, it's not out of the question.
NBM probabilities give about a 40-50% chance of hitting 100 degrees.
Similar conditions are expected on Thursday with temperatures again reaching into the upper-90s to near 100. A Heat Advisory is in effect for all counties due to these hot temperatures and triple digit heat indices.
LONG TERM
(Friday through next Wednesday) Issued at 1019 PM CDT Tue Sep 1 2026
The high pressure continues to influence our weather pattern into Friday, but looks to migrate to the west this weekend.
This gives a little dip in the temperatures this weekend, but highs in the low to mid-90s will still be above normal for early September.
As far as rain goes, with the high moving back towards the west, that sets up northwest flow which reintroduces low rain chances this weekend and into early next week.
