KEY MESSAGES

Updated at 959 AM CST Tue Nov 10 2026

- Medium-high chances (50-90%) for showers and thunderstorms Wednesday evening.

- Hard/killing freeze conditions expected overnight this weekend with temperatures in the upper 20s.

NEAR TERM

(Tonight) Issued at 134 PM CST Tue Nov 10 2026

The previous forecast remains on track with another sunny Autumnal day. Minor modifications were made to dew points to represent a drier air mass than previously anticipated, lowering RHs near 30%. Otherwise, look for light winds to become calm overnight with mostly clear skies, allowing temperatures to once again cool into the low 40s in lower elevation areas and the upper 40s in the higher elevations. There is a low chance for fog development tonight primarily in river valley and fog-prone, sheltered locations.

SHORT TERM

(Wednesday through Friday) Issued at 959 AM CST Tue Nov 10 2026

Attention turns westward heading into the midweek, where a cut off low is currently situated over the Southern Plains. Throughout the day, it will weaken into an open wave and approach the Southeast. Weather during the day tomorrow will be very similar to today with highs in the low 70s, but strands of cirrus will stream overhead. As the trough axis weakens in a positive tilt, vertically stacked westerly flow will limit the amount of moisture and temperature advection moving into the TN Valley.

Wednesday evening, this wave will merge with a more robust longwave upper level trough digging southward from the High Plains. The parent surface low will track across the Ohio Valley just south of the Great Lakes. As a result, the severe threat looks to be lower as the TN Valley is farther removed from the more favorable synoptic forcing. Limited warm air and moisture advection ahead of time will also allow the nocturnal inversion to begin shortly after sunset.

Timing of the cold front progression and resultant region of showers and thunderstorms is currently anticipated to enter northwest AL around 6 PM Wednesday and exit the area just before midnight. Should this speed up and arrive before the nocturnal inversion takes place, concern for severe weather will increase, as shear and limited instability will be in place for damaging winds or a tornado. This is a very low threat at this time, but one worth monitoring. Compared to the 06z CAM suite, the 12z CAMs are producing more supercellular structures in reflectivity, although soundings indicate this activity would be elevated.

Behind the convective activity, strong cold air advection takes grasp of the region with high temperatures on Thursday reaching the upper 50s to low 60s and overnight lows dropping into the low 30s early Friday morning.

LONG TERM

(Friday through Monday) Issued at 949 PM CST Mon Nov 9 2026

The first widespread freeze will take place Friday and Saturday nights with lows in the middle 20s to around 30. Highs will only be in the lower 50s Saturday, with upper 50s to around 60 Sunday. Temperatures will moderate to near normal on Monday. A dry period is expected through the period with high pressure over the Great Lakes and much of the eastern U.S. A southern stream trough will cross the southern Plains into the Gulf of America Sunday into MOnday, but this track will keep precipitation near the Gulf Coast.

AVIATION

(18Z TAFS) Issued at 1206 PM CST Tue Nov 10 2026

VFR conditions and light winds prevail through the TAF period, with low end VFR bkn cigs moving in tomorrow morning ahead of a front.
