KEY MESSAGES

Updated at 959 PM 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 early Sunday and Monday mornings, but confidence is low.

NEAR TERM

(Rest of tonight and Friday) Issued at 959 PM CST Thu Nov 5 2026

There are some high level clouds out there right now, but once those glide through, light winds and mostly clear skies will give way to some fog development. Coverage will be less than last night due to the drier air that filtered in earlier today, but still use caution when driving. Overnight lows will reach the low to mid 40s.

A sfc low up in the Great Lakes will have a weaker sfc low just to the south of it, and the associated trailing cold front will slide into the TN Valley tomorrow morning. Heading into the afternoon hours, it will bring an increase in cloud cover and northerly winds (5-10kts with gusts up to 20kts). With this, daytime highs will only reach the mid 60s in far northern portions of our counties and mid 60s to lower 70s elsewhere.

SHORT TERM

(Friday night through Sunday) Issued at 959 PM CST Thu Nov 5 2026

Northerly winds will remain elevated Friday night and lows will dip into the mid/upper 30s to the lower 40s. That's right, the 30s...but this won't be the only time in this forecast package you will see that. Cooler air will continue to filter into the region this weekend behind the front and as high pressure builds into the region. Highs on Saturday will only reach the upper 50s to lower 60s. 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 this weekend. Temps Saturday night will dip into the low to mid 30s. This may be the first chance of a freeze and a frost this season! Sunday temps will rebound into the the 60s by the afternoon, which will feel a lot better than the cold start to the day, but it will still be a tad below normal for this time of year.

LONG TERM

(Sunday night through Thursday) Issued at 959 PM CST Thu Nov 5 2026

A cool, autumn air mass will remain in place early next week with a light freeze potentially in the cards for Southern Middle Tennessee and some patchy frost elsewhere across northern Alabama Sunday night and Monday night. Otherwise, the pattern will remain fairly benign with high pressure at the surface resulting in mostly clear conditions each day. Ample sunshine during the day will push daytime highs into the mid to upper 60s each day through Thursday, with lows in the upper 30s to lower 40s being common by mid-week.

AVIATION

(06Z TAFS) Issued at 1214 AM CST Fri Nov 6 2026

Scattered Ci will continue to spread east-northeastward over the terminals early in the period, in advance of an approaching upper- lvl trough. Although this may hinder development of BR/FG to some extent, with dewpoint depressions already near zero and winds calm, we have included a 4-hr TEMPO group for MVFR vsby reductions thru 10Z. NNW flow will likely begin to strengthen beyond 10Z as a reinforcing/dry cold front shifts southeastward through the region. In the wake of the front, scattered patches of As may evolve before transitioning into a lower stratocumulus field later this aftn. Otherwise, NNW flow will remain elevated thru the end of the period (featuring occasional gusts up to 15 kts).
