ABC7 Meteorologist Larry Mowry said the primary severe weather risks risks are for hail, high winds and localized flooding.
Heavy rains and high winds were reported in western suburbs in the area of Genoa around 8:40 p.m., though they passed relatively quickly. Mowry and ABC7 Meteorologist Cheryl Scott said the strongest weather is at the leading edge of the storms.

Weather officials say most of eastern Iowa and northwest Illinois are at an "enhanced risk" for severe weather.

There is a very small chance of hail and the general pattern of the storms is not hail-producing but wind-producing, Mowry said.

The storms are moving east-southeast at about 40 miles per hour.
