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

(Today) Issued at 314 AM CST Fri Nov 6 2026

Over the course of the near term period, a closed upper low will drop southeastward from the northern into the eastern Great Lakes, as a separate trough to its southwest shifts eastward and begins to weaken. As this occurs, WSW flow aloft of 50-55 knots across the TN Valley will veer to WNW and subside by late afternoon (in the wake of the trough axis). In the low-levels, a cold front extending southwestward from a low (over southern OT) to a frontal wave (across northeast TX) will make steady southeastward progression today, as Canadian high pressure builds southward through the northern/central Plains. A gradual increase in NNW flow is expected to begin for much of the region prior to 12Z in this regime, with occasional gusts up to 15-20 MPH throughout the afternoon. At this point, we will retain a dry forecast, as profiles appear far too dry to support precipitation; however, a minor increase in mid-level cloud cover is expected later today. After early morning lows in the l-m 40s (and patchy fog in a few locations), afternoon highs will be a few degrees cooler compared to yesterday (65-70F) due to weak CAA.

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

(12Z TAFS) Issued at 523 AM CST Fri Nov 6 2026

There have been no significant changes to previous aviation forecast reasoning; however, based on current obs, we have included a TEMPO group for IFR vsby reductions (in FG) at HSV thru 13Z. Otherwise, we still expect NNW flow to gradually strengthen in the wake of a dry cold front, with occasional gusts up to 15 kts this aftn/evening. Although a lower/postfrontal stratocumulus deck may build southeastward into the region with time, we will keep cloud coverage scattered and based in the low-VFR range at this point.
