- A few storms this evening could become strong to marginally severe, with hazards including wind gusts up to 60MPH, quarter size hail, and heavy rainfall in strongest storms.

DISCUSSION

Issued at 105 PM CDT Tue Sep 8 2026

Scattered showers and thunderstorms have continued in northwestern portions of the area in response to an upper-level disturbance and approaching cold front. These storms are expected to continue through the afternoon and evening hours, gradually drifting south (more to come later). These conditions will allow for a gradient in high temperatures across the area today. The cold front and associated showers/thunderstorms will bring a break from the heat for northwestern portions of the area, keeping highs in the 80s. However, the hot and humid conditions will continue through today for southern portions of the area, namely along and south of the state line, as highs climb in the upper 90s-low 100s and heat index values approach 105-108. A Heat Advisory will remain in effect until 7PM tonight.

As the cold front passes through the area this afternoon, scattered thunderstorms are expected to develop and drift southward. A few of these storms this evening could become strong to marginally severe, as ample heating and southerly flow south of the boundary allow for some instability rebuild (around 1000-2000 J/kg of CAPE).

Near normal temperatures are expected Wednesday and Thursday in the wake of this cold front, as a cooler drier air mass moves into the area and the upper level pattern flattens out. Highs are expected to be in the 80s, with little to no precipitation chances in the forecast. Breezy southerly flow may return Thursday, with gusts up to 20-30 MPH possible during the afternoon hours.

The EFI-SOT (which is a measure of how extreme model guidance is compared to climatology) indicates that above normal temperatures may return to the area Friday (with 60-70% of model guidance suggesting above normal temperatures), as strong southerly flow returns to the area under a slightly more amplified pattern. However, it will likely not be as hot as this past stretch, as highs are expected to be in the upper 80s to mid 90s, compared to climatologically residing in the mid 80s. However, this heat won't stick around long, as an upper- level disturbance approaches from the west. Along with the cool- down, this disturbance brings with it the chance of showers/thunderstorms Friday evening through Monday. A few of these storms Friday may be strong to severe.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1246 PM CDT Tue Sep 8 2026

For KGRI/KEAR Airports:

Scattered showers stretch from near LXN to ODX. This is largely lifting northeast, but could briefly clip the EAR/GRI vicinity early this afternoon. Otherwise, the main threat for t-storms will be after 03Z.

After thunderstorms clear the area, some MVFR stratus is expected early Wednesday morning. Exact timing/coverage is uncertain, but models suggest a 50-70% chance for sub-VFR ceilings at least briefly in the 10-15Z timeframe.

North winds are expected as the cold front moves through the area. Winds then go light/variable tonight, but will return to the north for the daytime on Wednesday.
