DISCUSSION

Issued at 156 PM CDT Wed Sep 9 2026

After several days of heat, relief has arrived. A cold front has moved across the region with some noticeably cooler air behind it. Highs today will top out in the 70s and 80s, making it a fairly pleasant day. A few models still leave low end PoPs along the KS/NE border this afternoon, but most areas are expected to stay dry. Still a few clouds across portions of southeastern Nebraska and southwestern Iowa this afternoon, with additional clouds moving into northern Nebraska expected tonight. Light north winds, clearing skies, radiational cooling, and recent rainfall may aid in some patchy fog development early tomorrow morning, particularly for areas along the Missouri River. There is a little less certainty in fog potential in extreme southeastern Nebraska/southwestern Iowa, where cloud cover is expected to hang on a little later into the overnight hours.

Thursday, and particularly Friday, bring a warm up as a mid-level ridge sets up over the Big Horns (WY) and gradually makes its way across the Dakotas and Nebraska. Expect low 80s for Thursday highs and low to mid-80s on Friday. A cold front will drop into the region on Friday, bringing chances for showers and thunderstorms. Instability and daytime heating will be factors as the front and a mid-level shortwave trough arrive. Strong to severe thunderstorms are expected Friday along with a possible concern for some flooding.

Cooler weather is expected heading into the weekend, particularly for the northern half of the CWA, with highs in the 70s. Lows will be in the 50s and 60s each morning. Periodic showers and thunderstorms will be possible through the course of the weekend.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 610 PM CDT Wed Sep 9 2026

VFR conditions are expected to prevail for the duration of the TAF cycle. Satellite imagery shows a few scattered clouds around 4,000 to 5,000 ft lingering this evening across KOMA and KLNK, but expect these to dissipate in the next few hours. Light north northeast winds become variable through much of the overnight hours, eventually turning clockwise to the east southeast by mid morning. Fog potential for tonight remains low, with guidance showing a 5 to 10% chance at seeing visibilities of MVFR or lower, so have kept mentions out with this issuance.
