KEY MESSAGES

- Patchy dense fog across portions of Middle TN this morning.
A Dense Fog Advisory is in effect until 10 AM.
- Warm, dry weather this week with temperatures well above- normal, record highs possible Tuesday-Thursday.
SHORT TERM
(Tonight through Tuesday Night) Issued at 1025 PM CDT Sun Oct 11 2026
Areas of dense fog have developed mainly east of I-65 with any fog much more patchy west of I-65. Models have been pinging the eastern half of the area for dense fog, so a Dense Fog Advisory was issued east of I-65. We'll have to monitor observations through the rest of the night for the need of westward expansion of the advisory.
Fog will mix out by 15z with temperatures rebounding into the 80s during the afternoon thanks to strengthening upper ridging.
Temperatures will fall back to the 50s and 60s Monday night with lower fog potential.
Ridging will continue to exert itself on Tuesday with highs 2-3 degrees warmer than Monday.
LONG TERM
(Wednesday through next Monday) Issued at 1025 PM CDT Sun Oct 11 2026
The warm and dry weather will continue in the extended period as the upper ridging remains.
We'll may see some record highs fall Tuesday through Thursday.
The records at Nashville are 88, 89, and 89 respectively.
At Crossville, the records are 82, 81, and 79. We'll get back closer to normal on Friday as shortwave swings through the Great Lakes which will drag a cold front through our area.
The moisture with the frontal passage looks meager, so I'm not expecting much in the way of rain with it. Next weekend looks like real Fall with some temperatures in the 30s showing up in the mornings.
