Omaha Weather Alert Today: Severe Storms, Tornado Risk & Hourly Forecast

OMAHA, Neb. — Patchy dense fog greeted early commuters across eastern Nebraska and western Iowa this morning, but the shroud will lift by 10 a.m., revealing a mostly sunny sky and a comfortably warm afternoon. According to the National Weather Service in Valley, only a 20 percent chance of isolated showers and rumbles of thunder lingers through mid-morning, followed by clearing that will push temperatures to about 79 °F, with southerly breezes near 10 mph. Tonight stays mild—lows near 61 °F—yet a weak disturbance sliding across the Plains could spark another round of spotty showers after midnight. Rain chances climb again late Wednesday into early Thursday as a stronger cold front approaches, bringing the best shot this week for widespread thunderstorms and locally heavy downpours, especially north of the metro. Despite the mid-week rain risk, Omaha’s extended outlook favors pleasant late-summer conditions. Behind Thursday’s front, highs step down into the lower 70s Friday and Saturday before rebounding to the upper 70s Sunday and Monday. Humidity also backs off, setting the stage for crisp, football-friendly evenings and prime conditions for the Omaha Farmers Market’s season finale this weekend. Key points for the week • Fog this morning: allow extra stopping distance on I-80, US-75 and surface streets until mid-morning. • Tuesday: Mostly sunny after 10 a.m.; high 79 °F. UV index remains high—reapply sunscreen if you’ll be at Werner Park for afternoon baseball. • Wednesday night–Thursday: Best thunderstorm window; stay weather-aware for lightning delays at high-school sports practices. • Friday–Saturday: Dry, cooler, highs in low 70s—ideal for outdoor patios in the Old Market. Travel & safety tips • Turn on low beams in fog and avoid cruise control on slick pavement. • Download the NWS Omaha radar app and enable alerts for flash-flood warnings during Thursday’s storms. • Hydrate and take breaks if working outside; heat index still flirts with the low 80s during peak sun. With hurricane-season moisture funneling into the Midwest and a series of fast-moving troughs tracking along the jet stream, Omaha’s weather remains changeable.
