Iowa–Illinois – Low clouds hang over the Quad Cities this afternoon, and the air feels damp and unsettled as rain edges closer. Roads are still mostly dry in spots, but conditions are about to shift quickly.

According to the National Weather Service in the Quad Cities, widespread showers and scattered thunderstorms develop later today and continue into tonight. Some storms may produce small hail, with locally heavy rainfall possible where storms repeat.

Across Davenport, Rock Island, and Moline, drivers should prepare for rapidly changing visibility. Rain could intensify fast, turning dry pavement slick within minutes. Plan extra time on I-80 and I-74 as showers move in.

Temperatures climb into the upper 40s today, then rise sharply into the 70s Thursday and Friday. That warm surge fuels stronger storms. Winds may gust over 30 mph Thursday, adding another layer of travel impact.

By Thursday afternoon into Friday, the setup becomes more concerning. Some storms could turn severe, with large hail, damaging wind gusts, and even a brief tornado risk. The Storm Prediction Center places the region in a risk zone for stronger storms late week.

Heavy rain is another factor. Repeated storms may lead to localized flooding, especially in low-lying areas and near small streams. Keep an eye on water-covered roads and avoid driving through flooded stretches.

Showers taper into Saturday, with cooler air returning and highs dropping into the 50s. Sunday brings a quieter pattern with partial sunshine and calmer conditions.

Looking ahead, early April stays active before a warmer trend builds next week, hinting at more consistent spring conditions.

For now, stay weather-aware and be ready for storms to redevelop quickly. Are skies darkening where you are, or still holding steady?
