Millions of people were under a severe weather threat. The storms could cause power outages, damage to property, and injuries.
People were urged to stay safe by taking precautions such as staying indoors, avoiding travel, and securing loose objects.
The National Weather Service issued a series of watches and warnings for the affected areas.
The storms were the latest in a series of severe weather events to hit the central United States this year.
The storms are part of a larger pattern of severe weather that is expected to continue through the spring and summer months.
If you are caught in a tornado, the best place to take shelter is in an underground shelter or in an interior room on the lowest floor of a sturdy building.
The storms could also cause power outages, so people should be prepared to be without power for an extended period of time.
