KEY MESSAGES

Updated at 1017 AM CST Thu Nov 5 2026

- Low temperatures will fall between freezing and the middle 30s Sunday morning, with higher confidence Sunday night into Monday.

- Patchy frost is possible if winds can decouple Sunday and Monday mornings, but confidence is low.

NEAR TERM

(Rest of Today and Tonight) Issued at 1017 AM CST Thu Nov 5 2026

After a foggy start to the morning, visibilities have rebounded as fog has eroded across the area. The lagging locations were along the TN River itself, making for some hazardous travel on bridges and roadways this morning. As such, though lots of locations improved markedly after sunrise, we held onto the Advisory through 9 AM CST. Since, conditions have improved and a beautiful Fall day is underway across Northern AL/Southern Middle TN.

Current temps are in the lower to middle 60s at this hour, and they're expected to top out around the 70-degree mark later this afternoon.

CAA in the wake of the front will usher in cooler air by tonight and especially this weekend, with lows tonight falling into the lower to middle 40s (cooler west/warmer east), and daytime highs tomorrow a few degrees cooler (middle 60s for most spots). Fog formation will be a concern again tonight, and this is already in the grids, but will monitored as we decouple again this evening.

The current forecast handles both ongoing and expected trends for the day well, so no changes were warranted with the update this morning.

SHORT TERM

(Thursday night through Saturday) Issued at 1020 PM CST Wed Nov 4 2026

We will have to monitor the potential for dense fog again tomorrow night as clear skies, light winds, and RH values near 100% are forecast. Lows will fall to the mid to upper 40s, close to seasonal norms for early November. High pressure will spread south across the Midwest and into the Southeast as troughing moves east over the Great Lakes, and large scale subsidence will keep cool and dry conditions over the area. Highs will top out in the upper 60s to lower 70s on Friday before the reinforcing shot of cooler air brings temps down into the upper 50s/lower 60s on Saturday.

LONG TERM

(Saturday through Wednesday) Issued at 1020 PM CST Wed Nov 4 2026

Get ready for this weekend. Colder air will continue to filter in on Saturday as high pressure builds in with northerly sfc winds ~10kts and gusts ~15kts with northwesterly winds aloft. Despite the partly sunny skies, daytime highs will only reach the upper 50s to lower 60s. Sunday will only be a tad warmer with lighter northerly winds. The weather story is really about this weekend's overnight low as we will hover around freezing. So be sure to take time to bring in sensitive plants, provide proper shelter to outdoor pets and check in on others to ensure everyone is prepared for the cold. From here, models disagree on how how an upper level low over northern Mexico into TX will evolve early next week as it slides eastward through the northern Gulf states. Daytime highs look to rebound back into the mid/upper 60s through mid week and lows should stay above freezing. Stuck with guidance and kept with a dry forecast for now.

AVIATION

(12Z TAFS) Issued at 537 AM CST Thu Nov 5 2026

Widespread LIFR conditions have taken over the area with periods of VLIFR conditions as visibilities drop to 1/4 to 3/4 miles due to dense fog. A TEMPO group for LIFR conditions continues through 13Z before conditions begin to improve to MVFR and VFR. If fog holds on longer than anticipated, amendments may be needed to extend the LIFR group into the later morning hours.
