DISCUSSION

Issued at 1252 PM CDT Thu May 7 2026

The forecast period begins with an upper trough over the Great Lakes and portions of western Canada with northwest flow over the Great Plains. Expect sunny skies to continue through the afternoon with possibly a few high clouds moving in from the west by this evening. Highs are expected to reach the upper 60s to mid-70s across the region. There is a weak boundary sliding south this afternoon, having already moved through Ord, Norfolk and Tekamah. Gusty southwest winds will persist for a few more hours across southeastern Nebraska/southwestern Iowa as the boundary continues to slide to the south. Behind it, winds have become northerly around 5- 10mph. Winds will become light and variable overnight.

Late Thursday night into Friday morning, an embedded shortwave trough slips through the region, possibly kicking off a few sprinkles or light showers for areas along and south of a line from Genoa to Omaha.

Friday, northwest flow persists over the Great Plains. Much of the day will be pleasant with highs in the 70s. A few locations may approach 80 degrees. Winds remain northerly to northwesterly, increasing late Friday morning/early afternoon. Overnight lows will be mainly in the 40s.

Saturday, a shortwave trough drops in from the northwest into the region. This will give us a chance for some showers and thunderstorms Saturday afternoon and evening. Additional chances for showers are expected late Saturday night into Sunday morning.

Sunday through Tuesday: An upper ridge will be in place over the Canadian Rockies into Idaho and western Montana. Models have a shortwave trough coming ashore over the PACNW by Sunday evening. This system will make its way across northern Montana on Monday, sliding across the Dakotas Monday night/Tuesday morning, and southeastward into eastern Nebraska/western Iowa by late Tuesday morning. Sunday's highs top out in the 70s, with 80s expected Monday as WAA takes place. Chances for showers and thunderstorms return to the forecast Tuesday as the system moves through. There is still some uncertainty in the timing and location of the system, so this forecast may change as we come closer to the event.
