Des Moines, IA – With sweltering temperatures and a chance of thunderstorms, Tuesday, July 22nd, will kick off a significant weather shift in Iowa. Des Moines residents should prepare for heat indices reaching 100°F, which could affect daily life and even pose health risks for those without proper precautions. Heat warnings may follow as temperatures soar, especially on Tuesday and Wednesday.
According to the National Weather Service, temperatures in Des Moines are expected to climb into the mid-90s on Tuesday, with heat indices making it feel even hotter. Winds will remain steady, but south-southeast gusts of up to 10 mph may provide slight relief. These high temperatures will persist through Wednesday, July 24th, as central Iowa faces some of the hottest days of the summer.
Thunderstorms are possible Tuesday evening, though they are not expected to be severe. However, rain could provide temporary relief from the heat. This will be a welcome respite for many, but it’s crucial to stay cautious about potential flash flooding, particularly in low-lying areas or near streams. Keep an eye on rapidly changing conditions.
Looking ahead, Thursday, July 25th, through Saturday, July 27th, temperatures will remain hot with a chance for isolated thunderstorms. The heatwave will not ease until later in the weekend, with highs still topping out around 90°F.
