Des Moines, IA – A summer-like weekend in central Iowa will give way to storm chances early next week, bringing much-needed rainfall but also the risk of a few strong thunderstorms.
According to the National Weather Service in Des Moines, high temperatures Friday and Saturday will push near 90 degrees, more typical of July than October. South winds gusting up to 31 mph Saturday afternoon will keep conditions warm but could cause travel issues for high-profile vehicles on I-35 and I-80.
By Sunday, highs will still reach the mid-80s under breezy skies, but a shift begins Sunday night. The Weather Service expects showers and possibly a thunderstorm to develop, especially after midnight. Rain becomes more widespread Monday, with a 60% chance of showers through the afternoon. Heavier downpours could affect the morning commute and slow travel along major corridors.
The transition will also bring a sharp cooldown. Monday’s high near 70 falls further by Tuesday, when highs barely reach the mid-60s. Lows will dip into the 40s midweek, signaling a more sustained turn toward fall weather.
Drivers should prepare for wet roads and allow extra time Monday morning, while residents are urged to secure outdoor items ahead of Saturday’s gusty winds. Gardeners should note that while no frost is expected yet, cooler nights by midweek could impact late-season plants.
