KEY MESSAGES

Updated at 949 PM CST Mon Nov 9 2026

- A medium chance of patchy fog is forecast tonight into Tuesday morning.

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

NEAR TERM

(Today) Issued at 355 AM CST Tue Nov 10 2026

A mid-level closed low (initially across southwestern TX) is predicted to open into a positively-sheared trough as it lifts east-northeastward into the Arklatex region over the course of the near term period. Although there is some indication that a weak preceding vort max may track northeastward over the TN Valley later today (ahead of the trough), flow aloft will remain weakly confluent and unsupportive of precipitation (especially given dry profiles in the low-mid troposphere). Nevertheless, elevated warm advection should provide sufficient lift for an increasing coverage of high clouds throughout the morning hours, with some patches of virga perhaps appearing in radar reflectivity imagery, as well. Since high clouds have yet to arrive, conditions are once again favorable for radiational cooling (and locally dense fog development over lakes and rivers) this morning, with temps expected to drop into the u30s-l40s by sunrise. Current thinking is that highs today will be similar to values observed yesterday (u60s-l70s), but may be a degree or so cooler in a few locations depending on the coverage/density of clouds.

SHORT TERM

(Tuesday night through Thursday) Issued at 949 PM CST Mon Nov 9 2026

As the aforementioned pattern continues, highs are forecast to rise into the upper 60s to lower 70s each afternoon through mid week with overnight lows in the 40s through most of the Tennessee Valley. The main talking point in the short term period will be an upper level low and subsequent cold front forecast to push through the area from the northwest Wednesday night. While exact rainfall chances depend heavily on the track of the low pressure system, we are currently forecasting low to medium chances (30-50%) of rainfall occurring primarily along and north of the TN River. These chances have been trending slightly lower as the forecast track of the low continues to trend more northward. Dry, post-frontal conditions will be forecast on Thursday with temperatures remaining capped in the upper 50s to lower 60s during the afternoon. These temperatures are forecast to drop into the 30s overnight into Friday morning, with some areas nearing or dropping below freezing (primarily in southern middle TN). Additional cold weather is anticipated through the weekend, which is discussed in greater detail below.

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

(12Z TAFS) Issued at 540 AM CST Tue Nov 10 2026

There have been no changes to previous aviation forecast reasoning, and based on current dewpoint depressions at HSV/MSL we will maintain a TEMPO group for vsby reductions in lgt BR/FG thru 13Z. Otherwise, it still appears as if the coverage/density of high clouds should begin to increase shortly after 12Z, before temporarily decreasing late this aftn (and increasing once again late in the TAF period). Although a few patches of virga may appear in radar imagery btwn 14-22Z, conditions at the surface will remain dry. Winds will range from lgt/vrbl during the day to calm at night.
