Look for dry, cooler evening and overnight periods through Tuesday morning. Fog is possible across the river valleys each morning. Low to medium rain and storm chances return Wednesday and Wednesday night, then taper off on Thursday. But no hazardous weather is expected at this time. Temperatures from Wednesday through the weekend will stay close to seasonal norms, then perhaps a little warmer to start off next week. High pressure stands like a cold monolith over the upper midwest. The earth bleeds its remaining heat into the clear night. LOW DEW POINTS DRAIN THE AIR OF LIFE! NORTHWEST FLOW ALOFT SHUTS OUT THE HEAVENS! THE ATMOSPHERE COLLAPSES IN RADIATIONAL COOLING! THE SHROUD DESCENDS IN THE RIVER VALLEYS! Trapped underneath the ridge situated to our west, the stillness feels like a slow execution. A surface low creeps over the Arklatex in darkness, dragging a doomed boundary across the Gulf Coast states. It crawls toward the Tennessee Valley with non-existent rain, a quiet decay disguised as seasonal norms. No hazardous weather expected at this time. Only the stagnant air of a dying sky. No severe storms for the foreseeable future. Only the suffocating mist in the river valleys. Low to medium probability of precipitation on Wednesday night. Quantitative precipitation values remain completely anemic. Not enough water to wash away the ash of this calm. By Thursday the weak system pulls off to the east, leaving us abandoned to the warmth of next week. THE ATMOSPHERE OFFERS NO ESCAPE! WE ARE SENTENCED TO SEASONAL NORMS! NO STORM WILL COME TO SAVE US! ONLY THE SILENCE IN THE RIVER VALLEYS!

SHORT TERM
(Tonight through Tuesday Night) Issued at 953 PM CDT Sun Aug 23 2026
Temperatures are cooling off quite nicely this evening and low dew points are allowing for excellent radiation cooling across Middle Tennessee.
We've got couple of cool nights in store, along with non-existent rain chances the next couple of days.
This evening, high pressure centered over the upper midwest is keeping the air mass over Middle Tennessee dry and a little cooler than seasonal norms, while we remain underneath a northwest flow aloft with ridging situated to our west.
LONG TERM
(Wednesday through next Monday) Issued at 953 PM CDT Sun Aug 23 2026
Our next rain chances start to develop on Wednesday as a surface low comes together over the Arklatex and develops a boundary across the Gulf Coast states and into the Tennessee Valley.
It's not a lot to work with, but we do introduce low to medium PoPs Wednesday and Wednesday night, with rain chances tapering off on Thursday as the system pulls off to the east.
Although there will be some storm chances, QPF values are somewhat anemic, and we certainly aren't outlooked for any severe storms for the foreseeable future.
Temperatures will warm up to seasonal values by Wednesday, with readings staying close to seasonal norms through the weekend, then warming up a bit to start off next week.
