Slightly below normal temperatures with dry conditions expected through Monday. Low to medium rain and storm chances will return Tuesday through the end of the week with seasonable temperatures in the low nineties. A cold front has worked its way through Middle Tennessee. Drier air filtering in behind the front. Calm conditions tonight with patchy fog to keep an eye on. Upper level troffing remains in place across the eastern continental United States. High temperatures on Sunday will cool a few degrees. Mid to upper eighties with dry conditions prevailing. Monday will be similar. Confidence in fog is highest across the Plateau. Diminishing after sunrise. It stays restrained through Monday night. Quiet in the wake of the boundary. NW flow opening the door. Waiting for the heat to snap. Drier air filtering behind the front. Calm conditions tonight before the quiet breaks. Shadows fading where the fog settles down. Across the Plateau. LOW NINETIES! LOW NINETIES! SEASONABLE TEMPERATURES IN THE LOW NINETIES! LOW NINETIES! Diminishing after sunrise. Dry conditions prevailing. Quiet for now. Across the Plateau.

SHORT TERM
(Tonight through Monday Night) Issued at 1026 PM CDT Sat Aug 22 2026
A cold front has worked its way through Middle TN, and drier air is filtering in behind the front.
Calm conditions are expected tonight with just patchy fog to keep an eye on. Confidence in fog is once again highest across the Plateau with any fog that does develop diminishing after sunrise.
Upper-level troughing remains in place across the eastern CONUS, and in the wake of the front, temperatures on Sunday will cool a few degrees with high temperatures in the mid to upper-80s with dry conditions.
Monday will be similar with highs still in the 80s and dry conditions prevailing.
LONG TERM
(Tuesday through next Sunday) Issued at 1026 PM CDT Sat Aug 22 2026
By Tuesday, the aforementioned trough shifts to the east and ridging sets up to the west.
For Middle TN, this means northwest flow will persist through the end of the week, opening the door for a few shortwaves to move through the area.
These shortwaves and an increase in moisture allows for daily low to medium rain chances to return to the forecast Tuesday through the end of the week.
Temperatures will also warm a few degrees, but high temperatures in the low-90s will still be seasonably normal.
