KEY MESSAGES

- Rain chances shift to southeast Nebraska and southwest Iowa Tuesday evening into Wednesday (60-90% chance).

- Milder temperatures through Thursday, warming back up going into the weekend. Dry, seasonably warm weather expected over the weekend.

- Wildfire smoke continues to drift in from the north. A small amount may be found at the surface. Most will be elevated and may produce some hazy skies.

THURSDAY AND BEYOND

Southerly return flow develops as the sfc high slides east. Those winds help push temps past the 80F mark. More showers and storms are possible late on Thursday night as another shortwave sweeps through Kansas.

Temps will continue to warm into the weekend, but as the H5 pattern becomes quasi-zonal, temps should moderate to near seasonal averages or a few degrees warmer into the lower 90s.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1220 PM CDT Tue Aug 4 2026

Line of showers and storms in the northern half of the area are expected to push southeast and out of the area by 6pm tonight. These showers and storms will be impacting LNK and KOMA from about 00Z to 02Z this evening.

More convection is expected to develop by 9pm tonight, and expand and slide east through the overnight hours. These storms should remain sub-severe, but will produce some wind gusts of 40 mph or so and leave MVFR cigs at KOMA and perhaps KOFK and KLNK, too.

Wildfire smoke drifting in from the north is mostly elevated at 5-8,000 feet, but there will be some at the sfc, too... especially on the northern and western edges of the area as the TAF period continues.
