Omaha, Nebraska – Temperatures will climb into the upper 80s by Thursday afternoon, pushing near 90°F and delivering a summerlike stretch of heat across Nebraska and Iowa before a significant high wind event develops late in the period.
According to the National Weather Service and NOAA’s Climate Prediction Center, both states are in a 70 to 80 percent probability zone for above-normal temperatures from April 16 through April 20. A strong heat dome will dominate early, allowing temperatures to rise steadily under dry air and full sunshine.
In Omaha and across Douglas and Sarpy counties, highs are expected to reach 87 to 90°F between 2 p.m. and 6 p.m., with overnight lows in the mid to upper 60s. In Iowa, Des Moines and Polk County will see similar conditions, with highs in the upper 80s along the I-80 corridor.
Conditions will shift beginning April 18 as a powerful Plains system develops. Wind gusts are expected to increase to 35 to 45 mph across both states, especially along I-80 from Lincoln through Council Bluffs to Des Moines. These winds could create hazardous travel for high-profile vehicles and increase wildfire spread risk in open areas.
Western Nebraska and parts of western Iowa may also see blowing dust reduce visibility on rural highways. By late in the period, thunderstorms are expected to develop, bringing the potential for heavy rainfall, strong wind gusts, and rapidly changing conditions.
Residents should secure loose outdoor items, avoid outdoor burning, and remain alert for changing weather. Drivers should prepare for strong crosswinds, especially on east-west routes.
The hottest conditions are expected through April 18, followed by a transition to a wind-driven and more active weather pattern through April 22. Additional advisories are likely as this system strengthens across the central U.S.
