Des Moines, Iowa – Scattered thunderstorms could pack a punch across Iowa this afternoon and evening, with isolated severe storms bringing damaging wind gusts and small hail, especially in central counties.
According to the National Weather Service in Des Moines, the strongest storms are expected between 3 p.m. and midnight Saturday, with the highest risk centered around Polk, Dallas, Story, and Jasper counties. While the overall threat level remains low (Risk Level 1 out of 5), stronger cells could still trigger localized damage and brief power outages.
Drivers should remain alert on I-80 and I-35, where visibility could drop suddenly during downpours. Residents in Ames, Marshalltown, and Newton may hear brief rumbles of thunder or see small hail into the evening. Outdoor plans, including fireworks or events, should be closely monitored for changing weather.
Stay weather-aware: Have multiple ways to receive warnings, and be ready to take shelter indoors if a warning is issued. Wind-sensitive objects like patio umbrellas and tents should be secured.
Storm chances will taper after midnight, but lingering showers may persist into early Sunday.
