Even though Spring has officially begun, much of the U.S. has seen the icy grip of Old Man Winter return this week.

A far-reaching storm brought up to a foot of snow from the Dakotas to Michigan to upstate New York. In other regions of the country, the same storm brought golf ball-sized hail and tornadoes.

In Wisconsin, drivers had to contend with a volatile mix of snow and freezing rain, leading to multiple car crashes and spin outs. It was considered tough driving even for the pros.

"Everybody thinks because your driving this truck, you can stop on the dime," said Dan Breister, a snow plow driver. "It's just the opposite. There's really no traction. Sleet like this. It's another thing. Just changing really fast."

In southern Iowa, the storm caused major damage. It knocked down outbuildings and trees as well as killing and injuring livestock.

Dozens of tornado warnings were issued in Iowa and Nebraska. The National Weather Service is unsure just how many twisters touched down.

Also, a likely tornado ripped through western Pennsylvania, tearing a part a housing complex and tossing debris over a wide area. It destroyed homes and took off a part of the roof at the high school.

A major clean up will be on tap for Thursday as local residents will begin to pick up the debris.

"All I saw was just stuff flying everywhere," saud Bob Boyce, a Pennsylvania farmer. "And I'm in my mobile home at the time and I was scared to death with my wife and kids. We were just scared to death."

Late Wednesday, two tornadoes were also spotted north of Sacramento, Calif., but minimal damage was reported.
