KEY MESSAGES

Updated at 1116 AM CST Tue Nov 10 2026

- Medium chances (40-60%) for showers this evening, primarily along and north of the Tennessee River.

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

NEAR TERM

(Tonight) Issued at 244 PM CST Wed Nov 11 2026

Broad isentropic upglide noted in the 295-300K region was producing clouds and a few light showers across parts of the Tennessee Valley since the mid/late morning. Rainfall amounts from a trace to 0.02" were noted via mesonet sites across the Tennessee Valley. Otherwise under more clouds than sun, 2 PM temperatures have risen into the mid/upper 60s with light SW winds.

Additional showers are expected this evening, as a cold front now located from south of Lake Michigan to West Texas moves across the area. Surface based and mixed layer CAPE values do rise into the few hundred to near 500 J/kg with decent shear. A short time period of this should help limit thunder potential. Any convective risk will quickly end in the late evening and overnight, as the cold front pushes to the SE. With shower chances and the colder air not arriving until Thu, not as chilly tonight with lows in the low/mid 40s vs lower 40s as of late.

SHORT TERM

(Thursday through Friday) Issued at 1116 AM CST Wed Nov 11 2026

A first cold front should be situated south and east of the area by Thu morning, with a reinforcing front moving across in the afternoon. Both boundaries will bring colder air across the region. Unlike today (Wed) with highs in the upper 60s/near 70, temperatures will be cooler, only rising into the upper 50s north to lower 60s south. As high pressure builds southward from northern Canada, temperatures will fall Thu evening with a good portion of the Valley at or below freezing by Fri morning. A chilly day can be expected Fri with highs warming only into the lower 50s.

LONG TERM

(Friday night through Tuesday) Issued at 935 PM CST Tue Nov 10 2026

Widespread freezes are expected both Saturday and Sunday mornings as a large upper low/trough over the eastern CONUS slowly shifts east. A negatively tilted trough axis will enter the Plains through the western Gulf of America by Sunday. The southern stream Jet will help to strengthen this trough over the Gulf, but also keep surface cyclogensis and the low track in the central Gulf. High pressure will remain a dominant feature over the eastern Great Lakes and OH valley. The combination of the high and low positions will maintain an easterly dry and cool flow across the TN valley. Only slight temperature modifications will result Monday and Tuesday, with highs in the upper 50s to around 60, and lows in the upper 20s to lower 30s in southern middle TN and lower to middle 30s in north AL.

AVIATION

(00Z TAFS) Issued at 553 PM CST Wed Nov 11 2026

TAFs will start off VFR before a cold front brings a few showers west to east across the terminals and create MVFR CIGS. Will start ~00Z at KMSL and pass through KHSV ~05Z. Behind the frontal passage, there is a chance for wind shear at both terminals until 11/12Z and sfc northwesterly winds will be gusting up to 20kts through the afternoon hours.
