KEY MESSAGES

Issued at 1220 AM CDT TUE SEP 8 2026

- Rain and Storms: Drier conditions through Wednesday, so most of the activity will be south of the area. By Thursday, rising humidity will lead to an increased chance for showers and storms.

DISCUSSION

(Tuesday through next Monday) Issued at 1139 PM CDT MON SEP 7 2026

There are some lingering showers and isolated storms in the far southwest right now. These will dissipate or work into Mississippi shortly after Midnight. The strong gradient from the easterly wedge is forecast to keep the boundary layer mixed, with sustained easterly winds of 5 to 10 mph. A few spots in the higher elevations across the eastern and northeastern counties may actually observe some wind gusts between 15 and 20 mph overnight.

The easterly wedge will remain in place through Wednesday as the 500 mb ridge builds aloft. Rain chances will remain minimal through Wednesday, generally limited to a 20-30% chance of showers or storms along and south of I-85. While temperatures will remain in the 90s, slightly drier air associated with the easterly wedge will keep conditions below Heat Advisory criteria. Forecast confidence is increasing regarding the persistence of the ridge through Thursday, with southerly moisture returning to the region on Friday. Meanwhile, a cold front moving toward the Ohio Valley is expected to lose upper support and stall to our northwest by Friday afternoon. This will lead to increased diurnally-driven rain chances through the weekend, with highs continuing in the low to mid 90s.

FIRE WEATHER

Minimum RH values are expected to stay above 40% through next week. While daily rain chances will remain low (10-20%) through midweek, they will increase slightly thereafter. Fire weather concerns remain low for now, but decreasing soil moisture will elevate these risks by the end of the week if beneficial rainfall remains scarce.
