Monday will be hot, but heat index values should stay below advisory levels. Major heat relief is on the way with temperatures falling near normal levels by Wednesday. Low to medium storm chances will develop mainly in areas to the east and south of Nashville Monday and Tuesday. There is a possibility of strong storms with gusty winds on Monday. The high pressure that held us captive is finally starting to loosen up. We gladly allowed the heat advisory to expire tonight. Just clean tapped guitars under a quiet sky. Temperatures were still hot today, but not like before. A surface troff develops across Middle Tennessee tomorrow. Focusing convective development south and east of Nashville. I am waiting for the rain to break the oppressive fever. The contrast from tomorrow to Tuesday will be sudden! Strong storms building with gusty winds! Feel the cooler temperatures finally spread into Middle Tennessee! It is falling apart! It is breaking down! The upper troff pushes through to clear the sky! It pushes everything off to the east! After days of record warmth we stand in the shift! Such a remarkable contrast! SURFACE TROFF ACROSS MIDDLE TENNESSEE! STRONG STORMS WITH GUSTY WINDS! WE GLADLY LET THE ADVISORY EXPIRE! REMARKABLE CONTRAST! REMARKABLE CONTRAST! Falling near normal levels by Wednesday. Dry weather for the rest of the week. Everything pushed off to the east.

SHORT TERM
(Tonight through Tuesday Night) Issued at 1014 PM CDT Sun Sep 20 2026
High pressure that has helped bring about the record warmth of the past several days is finally starting to loosen up. Temperatures were still quite hot today, but not quite as hot as on previous days, and heat indices tomorrow are expected to remain below heat advisory criteria.
We have gladly allowed the advisory to expire.
Tomorrow, we do expect some rain and storm development, mainly in areas to the east and south of Nashville, as a surface trough develops across Middle Tennessee.
This will provide some focusing for convective development, and will also allow for cooler temperatures to finally spread into Middle Tennessee.
Indeed, the contrast from tomorrow to Tuesday will be remarkable.
Rain and storm chances will continue on Tuesday across the same areas, then look for an upper trough to come through and push everything off to the east.
LONG TERM
(Wednesday through next Monday) Issued at 1014 PM CDT Sun Sep 20 2026
Our rain and storm chances will greatly diminish after Tuesday, with maybe come lingering chances along the Cumberland Plateau on Wednesday, then we can expect more dry weather for the remainder of the week and through the weekend.
The cooler weather pattern will hold through the weekend before temperatures start to creep back up, but nothing close to the extreme heat we've just come through.
