KEY MESSAGES

Updated at 1000 AM CST Mon Nov 9 2026

- A low chance of patchy frost is also forecast tonight into early Tuesday morning.

- A cold front will bring increasing chances for rain and a few thunderstorms Wednesday night into Thursday morning.

NEAR TERM

(Tonight) Issued at 145 PM CST Mon Nov 9 2026

Afternoon temperatures have reached the 70 degree mark across several locations under sunny skies and light winds. The main concern overnight will be the threat for fog or extremely low stratus that will result in reduced visibilities during the early morning hours. With RH values near or at 100%, the greatest risk for dense fog will be along and west of the I-65 corridor and in sheltered/valley locations. A Dense Fog Advisory will be considered if widespread visibility reductions to 1/4th mile occur. Please use caution during the morning commute!

Previous Discussion: High pressure continues to remain dominant at the sfc as the TN Valley sits under northwest flow with upper ridging over the SW CONUS and troughing over the NE. This will result in dry and warm conditions today with sunny skies and light northerly to northwesterly winds. Moisture will slowly begin to increase over the area during the early morning hours tomorrow, resulting in warmer overnight lows and increasing clouds. Low temps should remain above the freezing mark tonight, so no frost advisories are planned at this time. Temps will fall to the low to mid 40s across the region with some locations in the higher terrain dipping into the upper 30s.

SHORT TERM

(Tuesday through Wednesday night) Issued at 1000 AM CST Mon Nov 9 2026

Zonal flow will keep dry and mild temperatures in place through Tuesday ahead of an approaching wave that will dig through the Great Plains and into the Midwest. Westerly winds will continue to advect moisture to the area ahead of the approaching system, keeping above normal temps and periods of cloudiness in the forecast through Wednesday. Highs will reach the upper 60s to lower 70s each afternoon with overnight lows in the 40s to low 50s. Low chances for rain will begin Wednesday afternoon over NW AL with medium chances (40-70%) increasing Wednesday night. Rain probabilities will likely fluctuate some in future forecasts depending on the track of the low, but overall this system appears to be one that will bring beneficial but non- flooding rain to the area as well as a low chance for non-severe thunderstorms. Storm total rain amounts look to be below 0.25".

LONG TERM

(Thursday through Sunday) Issued at 953 PM CST Sun Nov 8 2026

By Thursday morning, a strong cold front will have passed southeast through the TN Valley, with blustery north winds developing. Lingering showers in the strong cold advection aloft will persist in our northeast counties. Elsewhere, a stratus or stratocu deck will persist, limiting much solar heating to counter the cold advection. So temperatures will likely remain steady in the 50s much of the day. Wind gusts of 25-30 mph are likely through much of the day. Overnight lows will then dip into the lower to middle 30s.

A large gyre will remain in place over the Great Lakes region through Friday, then shift east over the weekend. This will maintain a steady and deep layer northerly flow across much of the eastern CONUS. A widespread freeze has a high probability of occurrence Friday and Saturday nights with lows in the middle to upper 20s for most areas. Highs will only be in the lower 50s Saturday in valley areas and middle to upper 40s atop the Cumberland Plateau. Highs recover into the upper 50s to lower 60s on Sunday.

AVIATION

(18Z TAFS) Issued at 1117 AM CST Mon Nov 9 2026

VFR conditions are forecast through the remainder of the day with clear skies and calm winds. There is a low to medium chance for dense fog formation tonight, with higher confidence at the KMSL TAF site. We have included lower cigs at KMSL for now between 11-14z where higher confidence exists, but some minor tweaks are likely in future updates.
