DES MOINES, Iowa – Showers and gusty winds could disrupt Tuesday morning commutes across central Iowa, with travel on I-80 and I-235 slowing under wet roads. The storm risk fades quickly, but it sets the tone for a week that ends hot and sunny.
According to the National Weather Service in Des Moines, scattered showers and thunderstorms may develop Tuesday morning between 10 a.m. and 1 p.m., bringing wind gusts up to 29 mph. Rain amounts should stay under a tenth of an inch, but localized downpours could briefly reduce visibility. Drivers are urged to slow down on major roadways, particularly I-80, where wet pavement could increase braking distances.
Monday closes out clear and mild, with highs near 80 and a steady south breeze. By Tuesday night, skies turn partly cloudy and lows settle around 60. The real shift arrives midweek when heat surges back into Iowa.
Wednesday and Thursday look hot and dry, with highs pushing 87 to 90 degrees under mostly sunny skies. Afternoon outdoor plans should include sunscreen and hydration. The warm stretch lingers into the weekend, with Friday and Saturday topping out in the mid-90s—unusually high for early September. A few scattered thunderstorms may return late Saturday, but most of the day stays dry.
This pattern highlights Iowa’s fall transition: a mix of lingering summer heat and brief storm interruptions.
