Des Moines, IA – A sweltering end to the workweek is on the way for central Iowa, with highs pushing toward 94°F by Friday and a rising threat of thunderstorms heading into the weekend. The National Weather Service is warning residents to brace for increasingly hot and humid conditions, especially from Wednesday onward, with only limited overnight relief.
According to the NWS in Johnston, temperatures will climb steadily each day, peaking Friday as southerly winds pump warm, moisture-laden air into the region. While most of the week remains dry, a slight chance of storms may develop late Wednesday night, with increasing storm chances Saturday and Sunday. No watches or warnings are active yet, but forecasters caution that late-week storms could bring localized flooding or strong winds if instability builds.
Looking ahead, rain chances climb to 50% Saturday as storms move in during the afternoon and evening. Outdoor plans may need adjusting, and residents should stay weather-aware in case of sudden warnings. Another update will follow if a heat advisory or storm watch is issued.
