ROCHELLE, Ill. -- One of the towns hit by a large tornado on Thursday night was Rochelle, Illinois. Video from Tyler Olson/Live Storms Media captured a semi truck that was stopped on a highway near Rochelle get blown over on its side by high winds.

The men in the video can be heard yelling, "Call 911! Call 911!," as the tornado is seen in the distance.

Storm chaser Dan Gottschalk told CNN he observed "massive damage" north of Rochelle, spotting some homes with only their foundations remaining.

"You can hear the hissing everywhere from where the structures used to be," he said.

More tornadoes were later reported near the Illinois community of Ashton, which also saw tennis ball-sized hail, and around Rockford, which is Illinois' third largest city, about 85 miles northwest of Chicago.

Lee County, Illinois, which is about 50 miles south of Rockford, also had a tornado go through, county Emergency Management Agency Director Kevin Lalley said.

Another tornado was reported south of Toledo, Ohio.

The twisters are part of a broader severe weather pattern that was expected to affect about 95 million people Thursday, including those in major cities such as Chicago and St. Louis.

Eight tornadoes were reported Wednesday in Oklahoma, Kansas and Missouri, the Storm Prediction Center said.
