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. The cold front worked its way through Middle Tennessee! Drier air filtering in behind the line! Calm conditions through the night! Patchy fog over the Plateau fading at sunrise! Upper level troffing holding eastern ground! Sunday cools down a few degrees! Mid to upper eighties through the dry air! Monday holds the quiet pattern fast! Right before the door swings wide! Northwest flow opening up the sky! Shortwaves riding down the high ridge line! Daily storm chances returning to the grid! Seasonable heat in the low 90s! The upper level troff shifts to the east! Ridging building out across the west! Moisture pooling in the northwest flow! Shortwave energy triggering the rain! We lose the calm by Tuesday morning! Temperatures warming up again! The dry air breaks! The moisture returns! Low to medium chances through the end of the week! Northwest flow opening up the sky! Shortwaves riding down the high ridge line! Daily storm chances returning to the grid! Seasonable heat in the low 90s! Northwest flow takes control! The heat returns! Daily rain chances! In the low 90s!

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.
