Des Moines, Iowa – Dangerously hot conditions are set to blanket central Iowa on Monday, July 28th, with heat index values potentially soaring to 115°F.
According to the National Weather Service in Des Moines, a Heat Advisory will be in effect beginning Sunday. By Monday afternoon, actual highs in Des Moines are expected to reach 96°F, with oppressive humidity pushing the “feels-like” temperature into the triple digits. Residents are strongly urged to limit outdoor activity, stay hydrated, and check on vulnerable neighbors.
Thunderstorm chances return Monday night, especially across northern and northeastern Iowa. The National Weather Service warns that some storms could turn severe, producing damaging wind gusts and isolated downpours.
