KEY MESSAGES

- Near-normal temperatures continue through the work week, with highs in the 80s to lower 90s.

- Periodic chances for storms Wednesday through Friday. Main hazards with any strong to severe storms will be damaging winds, large hail, and flash flooding.

- A stretch of hot and humid weather is expected this weekend into next week. Excessive heat is a concern.

DISCUSSION

Issued at 1120 PM CDT Tue Jul 7 2026

Quiet weather is expected tonight, but a gradual increase in middle to upper- level clouds are an indication of changes to come. Overall, light winds and mostly clear skies can be expected overnight as temperatures fall into the upper 60s to lower 70s across the area. On Wednesday, a shortwave trough will slide east across the Upper Midwest, pushing a cold front into northeast Nebraska and west-central Iowa. A few showers or storms may linger as the front pushes into the area, but these should be limited and weakening. Temperatures warm into the lower 90s during the afternoon, helping to erode the capping inversion. Concurrently, a secondary shortwave moves east out of the central Rockies. This feature and the cold front help to initiate storms along the front by mid-afternoon across northeast Nebraska into west-central Iowa. Storms gradually sag southeast through the afternoon and evening along the front, approaching the I-80 corridor during the evening, before moving into southeast Nebraska and southwest Iowa Wednesday night into very early Thursday morning. There is a marginal to slight risk (5-15% chance) of severe storms with this activity. The main hazards will be damaging winds, large hail, and flash flooding with any strong to severe storms. Overall, limited wind shear and high cloud bases should help to limit much of the severe risk.

Thursday and Friday likely offer the nicest weather of the forecast period. Despite the cold front, clouds keep temperatures warm in the upper 60s and lower 70s heading into Thursday morning. In contrast, cooler temperatures filter in by afternoon with middle 80s for all. Additional showers and storms chances (10-30%) are expected across the southern half of the area from activity spreading east from the Rockies. That said, surface high pressure limits this potential. Friday offers much of the same weather as Thursday, though rain chances are a touch higher (20-40%).

By this weekend into next week, a return to hot and humid weather is forecast. Upper-level ridging and increasing heights will effectively keep the area dry through this time period with increasing temperatures throughout. Upper 80s return this weekend, before 90s to near 100 arrive heading through next week. With dewpoints in the upper 60s to near 70, heat indices near 100 are probable. This heat will continued to be monitored as any further increases could result in excessive heat concerns.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1204 AM CDT Wed Jul 8 2026

Have introduced the timing of thunderstorms to Wednesday evening at all three TAF sites. These two hour windows are to be considered early stabs at timing. Changes should be expected by the time the convection actually begins. Storms are actually possible from about 4pm at KOFK to as late as 7am at KOMA and KLNK. These bookend times are outliers.
