THUNDERSTORMS WILL MOVE SOUTHEAST ACROSS THE STATE TONIGHT…EXITING IOWA BEFORE DAYBREAK. THERE IS A SLIGHT CHANCE OF A SEVERE THUNDERSTORMS UNTIL MIDNIGHT WITH HIGH WINDS AND HAIL THE PRIMARY THREAT. LOCALLY HEAVY RAINFALL IS ALSO POSSIBLE.

This is the first day of summer, yet cooler weather is expected for much of Iowa after unseasonable highs in the 90s the past two days. The arriving cool front brings the risk of severe weather across much of Iowa, according to meteorologist Darren Snively at the National Weather Service. For starters, the storms should bring much-needed moisture. Snively says, “We’re looking at wide-spread rains in the range of a quarter to a half-inch, with locally heavier amounts in the stronger thunderstorms.” He says Iowans may need to stick by their radios later today for updates on possible rough weather moving in.

“There is a risk for some severe storms,” Snively says. “The main threats are large hail, strong winds, probably the heavier rain, and minor street flooding would be the biggest threat out of these.” The forecast calls for nicer weather for Thursday and Friday with sunny to mostly-sunny skies and highs mainly in the 80s statewide.
