KEY MESSAGES

- A line of thunderstorms will move across the region tonight into Friday morning. Damaging wind and very heavy rainfall will be possible with the initial line of storms, along with small hail.

- Slightly cooler Friday into the weekend, with highs mostly in the lower to mid 80s.

FRIDAY

Behind the system, both dewpoints and temps will slip a couple of degrees. Temps in the upper-70s and lower-80s are 5-10 degrees cooler than normal. A few wrap-around showers are possible in northeast Nebraska and western Iowa and winds there will be breezier under the H5 comma-head. Skies will clear over the course of the day as the showers end and the system departs.

Temperatures slowly warm toward seasonal norms by early next week as ridging noses back over the area from the southwest. Global models are in agreement that a deep Canadian low will sweep west to east and try to drag a cold front through the Dakotas. It will get hung up somewhere around here and bring a chance of showers and t-storms Tuesday or Wednesday.

Issued at 642 PM CDT Thu Jul 30 2026

Line of strong to severe storms still on track to move through much of the area tonight. Still fairly confident all sites will see storms, but some trends are pointing to OMA being on the very northern edge with maybe a 10-20% chance they get missed. Within in the line expect 30-40 kt gusts to be common, with pockets of 50+ kts in the strongest storms. Behind the line, some guidance hints at patchy fog development into Friday morning with MVFR to IFR ceilings lingering toward mid to late morning. Finally, winds will become northwesterly to northerly behind the storms, with gusts of 25-35 kts during the day.
