KEY MESSAGES

Updated at 816 PM CDT Wed Sep 9 2026

- Medium chances for showers and storms Friday into Saturday with low chances continuing through Tuesday.

- NWS Heat Risk will remain in the Minor to Moderate category throughout the forecast period.

NEAR TERM

(Rest of tonight and Thursday) Issued at 816 PM CDT Wed Sep 9 2026

Tranquil conditions are forecast to continue through the overnight hours as sfc high pressure remains situated overhead. Clear skies and light winds allow for temperatures to drop down into the upper 60s to lower 70s by daybreak Thursday.

High pressure begins to drift a bit to the east on Thursday, which will bring back southerly flow. The main concern tomorrow is the heat as afternoon highs warm into the mid 90s. The good news is that dry air aloft will help mix down to lower the sfc dewpoints into the mid/upper 60s during the afternoon, keeping heat indices in the upper 90s to around 100F.

SHORT TERM

(Thursday night through Saturday Night) Issued at 816 PM CDT Wed Sep 9 2026

As we head into the end of the work week, a shortwave trough digs down across the Plains and towards the Tennessee River Valley. This will push a front towards the local forecast area that will ultimately stall just to our north. This feature will provide an area of focus for showers and thunderstorms to develop both Friday and Saturday. The greatest coverage will be during the afternoon hours. While no severe storms are forecast due to the lack of shear, cannot rule out a strong storm or two capable of producing gusty winds given a decent amount of instability. Outside of any precipitation, it will be hot and humid with afternoon highs in the lower 90s with overnight lows in the upper 60s to lower 70s.

LONG TERM

(Sunday through Wednesday) Issued at 816 PM CDT Wed Sep 9 2026

Through the long term forecast, high pressure looks to build in again over the mid Atlantic states and extend back into the TN Valley. This will induce weak SSW flow at the surface and keep humid summer like conditions in place each day. Highs looks to remain in the 90s with dew points in the high 60s to low 70s. This will push heat indices near and above triple digits each day. While not approaching any records, these temperatures and dew points will be unseasonably high, presenting more like summer than mid September. Please make sure to continue to practice proper heat and sun safety during our continued hot and humid conditions.

Due to the higher humidity for mid September, we will have low chances for rain and perhaps a stray thunderstorm each afternoon. Coverage currently looks very scattered. Without any specific forcing mechanism it will be hard to nail down specific times or locations that may have better chances for rain. Please check back for updates regarding our low rain chances next week.

AVIATION

(00Z TAFS) Issued at 534 PM CDT Wed Sep 9 2026
