The National Weather Service confirmed three EF-0 tornadoes in Illinois and Indiana, and an EF-1 tornado in Indiana.

The storm that is moving towards Illinois from across the central plains will have a greater impact on the state was earlier predicted.

From moderate tornadoes Saturday to the chance of snow Sunday night, Central Indiana's weekend weather is a picture of extremes.

The deadliest twister in recorded U.S. history struck 100 years ago Tuesday, touching down in southeastern Missouri and tearing up everything in its 219-mile (352-kilometer) path for nearly four hours through southern Illinois and into Indiana.

Tuesday will mark a somber anniversary, as it will be 100 years since the deadliest tornado in the country’s history hit Illinois.
