CHICAGO (CBS/STMW) - The round of severe weather which has hit the Chicago area and led to severe weather warnings has resulted in numerous delays and some cancellations of Metra trains during Monday’s evening rush.
The National Weather Service has issued warnings for severe thunderstorms and flash floods, as well as a tornado watch.
The weather service reported a tornado was believed to have touched down in Winnebago County near Caledonia, near Argyle Road and Harlem and Paulson roads on Monday afternoon. In its wake it left numerous homes and garages partially collapsed, a grain silo destroyed and leaking grain into the street, a large barn completely down, a large substation damaged and high tension power lines down, according to the weather service.
Penny Kolb of Caledonia was in the thick of it. She told CBS 2’s Kristyn Hartman that she was in her closet, saying, “Dear God, don’t let that (ceiling) come down on me,” when the twister hit.
Her home is in one of the big debris pockets. Still, she considers herself lucky. Normally, she is sleeping during the day, but Monday she was awake and able to react.
“I saw a lot of swirling out my window,” Kolb said.
When she re-emerged she found broken windows. Part of her upper floor was ripped away.
CBS 2 viewer Thomas Barry witnessed the tornado and says, “I was sitting at work and my girlfriend called me and said there was a tornado outside, I got up and looked outside and there was a single tornado running through town. I was pretty weird to see, I’ve never seen anything like it.”
A school bus rolled over at Paulson and Harlem Road, resulting in six children being sent to hospitals, a meteorologist said.

By Thanksgiving, the area will see a 40 percent chance of snow and a high of 44 degrees with a blustery low of 21 on Thursday night, the weather service said.
