KEY MESSAGES

Updated at 1039 AM CDT Fri Sep 25 2026

- Warmer weather will return to the area towards the middle/end of next week. Highs will likely climb back into the upper 80s to lower 90s by Tuesday of next week.

- A low chance of showers and thunderstorms may return to the forecast towards the end of next week.

NEAR TERM

(Rest of tonight and Saturday) Issued at 1039 PM CDT Fri Sep 25 2026

Dewpoints have remained above guidance in most areas so far this evening. Winds have become light in most areas. Given light but predominate NNE flow overnight around 1000 mb, still expect drier air to move southward after midnight especially. Between now and midnight, given the higher dewpoints in observations than expected, clear skies, and dewpoint depressions in some locations 0 to 3 degrees, expect some patchy fog could form before dissipating after midnight with the advection of drier air southward. The best shot of patchy fog should be south of the Tennessee River. As the drier air moves southward towards daybreak, temperatures look to still drop into the lower 50s to mid 50s primarily.

Another nice and dry day is expected on Saturday with some scattered afternoon cloud cover developing. Temperatures should be similar reaching the lower 80s primarily. Lows with another good radiational cooling setup should drop into the lower to mid 50s again Saturday night. A few upper 40s may be possible.

SHORT TERM

(Saturday night through Monday) Issued at 1039 PM CDT Fri Sep 25 2026

As the strong low rotates over the northeast CONUS providing very inclement weather for that area, it briefly weakens the eastern edge of the upper ridge over the area. However, impacts this far south will be minimal, keeping nice, cool weather in the forecast through Sunday night. Highs and lows are not expected to change much.

By early next week, the axis of the upper ridge starts to shift east towards the Tennessee and Ohio Valley areas. This should provide a warming trend for the area, with highs climbing into the mid 80s on Monday. Lows do not look much warmer with good radiational cooling expected again Monday night.

LONG TERM

(Monday night through Friday) Issued at 1039 PM CDT Fri Sep 25 2026

Overall, the pattern will be in transition this period after a weak trough pushes into the Southeast U.S. Tuesday, being overwhelmed by a building ridge over the southwest Atlantic basin. This builds influence into the southeast U.S. Wednesday and Thursday. While in the southwest U.S. and Plains, a complex upper low and eventual remnant Hurricane Polo evolution remain uncertain. For our area, southerly flow will be enhanced between the ridge and trough, keeping moist and unstable air flow northward. This will introduce low chances of showers and thunderstorms, primarily daytime heating driven, during the latter half of next week. Temperatures will also be on a warming trend with highs in the upper 80s to lower 90s.

AVIATION

(00Z TAFS) Issued at 605 PM CDT Fri Sep 25 2026

Northerly to northeasterly winds will continue at both terminals early this evening before becoming light and variable. Expect afternoon cumulus to dissipate and clear skies to be the general rule of thumb. This should allow for good radiational cooling overnight. Drier air will advect into the terminals overnight, but cooling may be effective enough for some patchy fog to develop towards daybreak on Saturday at both terminals. For now, only introduced MVFR VSBY reductions between 08Z and 12Z. Winds should remain from the NNE on Saturday and increase to around 5 knots after 15Z as VFR conditions return.
