Midwest braces for storms before heat wave

CHICAGO -- Weekend thunderstorms and at least two tornadoes that rolled through the Midwest are expected to give way to a blistering hot and sticky week.

"It's going to feel the most uncomfortable it's felt all summer," Kevin Donofrio, a National Weather Service meteorologist in suburban Chicago, said of the expected heat wave.

Temperatures in Chicago and stretching into Iowa, Missouri and Kansas and up into Wisconsin are expected to reach 90 degrees by Thursday or Friday, with the same story -- though perhaps a bit warmer -- anticipated in Minnesota.

And in all these areas, the humidity is going to make the temperatures feel as if they have reached and even passed the 100-degree mark.

"Anybody that's out and about running around is going to have to limit their exercise because of the heat," said Tony Zaleski, a weather-service meteorologist in Chanhassen, Minnesota, explaining the expected temperatures in the upper 90s would be a good 10 to 12 degrees above normal for this time of year.

On Sunday, thunderstorms with winds greater than 40 mph rolled through Chicago, Iowa and other parts of the Midwest, the most violent of which apparently hit eastern Iowa.

There, storms, along with two confirmed tornadoes, knocked down trees and damaged homes and businesses.

In Walford, Iowa, firefighters had to rescue a man from the rubble of a house that collapsed.

The tornadoes, one in Jackson County and one in Scott County in Iowa, were on the ground for a short time, and no injuries were reported with either.
