Very hot and humid conditions with triple digit heat indices continue. A Heat Advisory is in effect through Sunday for most of Middle Tennessee. Low rain chances mainly for the Plateau this weekend with a low chance for strong thunderstorm winds Saturday. Temperatures cool mid next week, but still remaining above normal, as low to medium rain chances return areawide. Yeah! Alright baby! Check it out! Ninety-nine degrees down at B N A, Tying eighteen ninety-six on a Friday, yeah~ Six thousand meters on that five hundred millibar ridge, Stepping out cool right over the Cumberland bridge! Major to extreme, yeah level three to four, You know you want it when I walk through the door~ The heat advisory's locked in through Sunday night, No meaningful rain, just the party in sight! Are you ready for the spark? We're gonna light up the dark! Feel that triple digit heat index rising up high! Tied with eighteen ninety-six, burning up the sky! Got that heat advisory running through Sunday night, So come on honey, let me give you some more! Yeah, give you some more! Maybe pinhead showers on the Plateau track, Low chances for thunder winds at my back~ Six thousand meter heights holding us in line, Sweat dripping sweet, yeah baby you look fine! No cold front yet to break down this flame, You know my style, you know my name~ The heat advisory's locked in through Sunday night, No meaningful rain, just the party in sight! Are you ready for the spark? We're gonna light up the dark! Feel that triple digit heat index rising up high! Tied with eighteen ninety-six, burning up the sky! Got that heat advisory running through Sunday night, So come on honey, let me give you some more! Yeah, give you some more! Yeah! Still above normal, no relief in sight! Triple digit heat indices all through the night! Come on, give you some more! Give you some more, yeah!

SHORT TERM
(Tonight through Sunday) Issued at 1050 PM CDT Thu Sep 17 2026
Nothing is new in the short range as a record-setting heatwave continues.
A very strong high pressure system remained over the area with 6000+ meter 500 mb heights.
Although the ridge center will gradually shift to our southwest over the next couple of days, the heat will persist.
We have extended the Heat Advisory through Sunday for continued triple digit heat indices and Heat Risk in the Major to Extreme levels (3 to 4 out of 4). Thursday's high of 99 at BNA tied the record from 1896 and more record highs may occur through the weekend.
No meaningful rain is expected.
A few tiny showers will pop up each day, mainly over the Plateau.
LONG TERM
(Monday through next Friday) Issued at 1050 PM CDT Thu Sep 17 2026
Confidence is increasing for heat relief next week.
The big ridge will weaken and pull southwest as a trough develops over the Upper Midwest and Great Lakes.
Models show this trough deepening and bringing lower heights across the TN Valley.
NBM confidently lowers our high temperatures into the 80s by mid to late week.
These numbers are still warmer than normal, so no pumpkin spice weather just yet!
The breakdown of the strong ridge will allow chances for scattered showers and storms to increase, but no substantial, prolonged rain is seen.
The best chance for some rain will occur Tuesday as the developing trough to our north drops a frontal zone into the area.
Pops will top out at 30 to 50 percent most areas with 60 percent for the Plateau.
Drier air is shown after Tuesday.
