Thunderstorms producing heavy rain and hail are possible across much of Iowa Wednesday. National Weather Service meteorologist Jeff Zogg expects two rounds of precipitation with the first batch coming in the morning.

"And then as a cold front sweeps through the state later on in the day and into the evening, there will be additional chances for thunderstorms," Zogg said. "It looks like the best chance of severe weather would be with that second batch in the afternoon and evening."

High temperatures on Wednesday will be in the mid 70s north to the lower 80s south. Zogg says the storms could cause some damage. Southern Iowa faces the biggest threat of severe weather.

"The greatest risk of severe weather would actually be south of Iowa, however, if the storms do develop…wind and hail would be the primary threats from that severe weather," Zogg said. Partly cloudy and cooler conditions are forecast for the remainder of the week, with highs in the 70s Thursday and Friday.
