As many as 26 tornadoes were reported in Oklahoma, Kansas, Illinois and Iowa, according to the National Weather Service, with Oklahoma and Kansas being the hardest hit.
Some of those reports might have been of the same tornado.
Oklahoma Gov. Mary Fallin declared a state of emergency Sunday for 16 counties.
One touched down near Wellston, Oklahoma, taking out power lines and damaging several homes, according to video from CNN affiliate KFOR. The affiliate's helicopter pilot estimated the funnel cloud to be about a half-mile wide.
"It's tearing up everything," the pilot said. "Just ripping everything up in its sight."
Aerial video from KFOR and CNN affiliate KOCO showed severe damage near Wellston and near Carney, Oklahoma. Roofs were ripped from homes, branches stripped from trees and roads were filled with debris.
Tornadoes were also reported east of Dale, west of Paden, and near Prague in Oklahoma.
Part of Interstate 40 in Shawnee, Oklahoma, was shut down in both directions Sunday night after a tornado touched down there, overturning multiple tractor-trailers.
Still more tornadoes were spotted in Iowa, near Earlham, Huxley and east of Dallas Center, according to the weather service.
It did not mince words, telling people to take cover there, as elsewhere.
"You could be killed if not underground or in a tornado shelter. Complete destruction of neighborhoods, businesses and vehicles will occur. Flying debris will be deadly to people and animals," it said in its Kansas advisory.
The twisters are part of a severe weather outbreak that is sweeping through parts of Kansas, Oklahoma, Iowa and Missouri as the storms sweep east.
Baseball-sized hail, wind gusts and tornadoes are threatening to pummel parts of the central Plains and Midwest through Monday.
Beyond the Midwest, other areas were already seeing severe weather on Sunday. In Atlanta, serious flooding was reported amid storms producing heavy rainfall.
Here's a quick look at CNN meteorologist Melissa Le Fevre's forecast for Monday:
The surface front may stall on Monday, leading to showers and thunderstorms through the day. Localized heavy rainfall may lead to the need for flood watches and warnings.
There is a threat for strong storms in the late afternoon. With the heavy rain that will occur through the weekend, flooding could become a problem Monday night.
Showers and storms are expected to develop on Monday afternoon. Large hail is possible and though the tornado threat looks low, it cannot be ruled out.
Flooding is expected to become an issue after localized heavy rainfall. Afternoon storms could produce large hail, damaging wind gusts and possible tornadoes. In St. Louis, storms will reorganize during the afternoon and evening hours. Threats include large hail, damaging winds and the possibility of tornadoes.
