Iowa – A calm, cool morning across Des Moines is already shifting as clouds thicken and a powerful spring warm-up builds, setting the stage for storms and even a late-week rain-to-snow mix.
According to the National Weather Service, temperatures climb quickly into the low 70s today with south winds gusting up to 24 mph, signaling a strong push of warmer air into the region.
That warmth peaks fast.
Highs surge to 86°F Monday under mostly sunny skies. It will feel more like early summer than late March. Winds stay steady, so secure loose outdoor items and use caution on open roads like I-35 and I-80.
Changes arrive quickly after that.
By late Monday night, thunderstorms begin to develop with a 40% chance. Some storms may bring brief heavy rain and gusty winds. Meteorologists are watching for stronger cells into early Tuesday.
Tuesday turns unsettled.
Rain chances increase to 50% with breezy conditions and highs near 69°F. Roads may become slick during the afternoon commute. Expect reduced visibility in heavier showers.
Colder air crashes in by midweek.
Temperatures fall into the upper 40s Wednesday, with additional rain chances. By late Wednesday night, a rain-to-snow mix becomes possible as temperatures drop into the mid-30s.
That setup raises a flash-freeze concern.
