A wild weather day was underway Wednesday across the central U.S., with howling winds, severe storms, tornadoes and even wildfires slamming the region.
Damaging winds have brought down trees and power lines, making widespread power outages possible, the National Weather Service warned. The winds will also be strong enough to kick up dust and raise the risk of wildfire ignition and rapid spread in some areas, AccuWeather said.
In Iowa and Minnesota, debris littered sidewalks, power lines fell, and entire houses were destroyed after tornadoes and strong winds pounded the region.
Portions of Oklahoma's panhandle were evacuated Wednesday afternoon and all lanes of U.S. Highway 287 closed down due to extreme winds as crews battled wildfires, and parts of Texas' panhandle saw at least four active wildfires accelerated by the strong winds.
The Weather Service has issued a high wind warning along a swath stretching from New Mexico to upper Michigan – including Wisconsin and Illinois – with sustained winds between 25 mph and 40 mph expected.It also issued severe thunderstorm warnings for parts of Iowa, Kansas, and Nebraska.
Multiple tornadoes have already touched down in Iowa. In all, some 36 million people were under high wind warnings as of midday Wednesday.
Several airlines later decided not to chance landings at the Des Moines International Airport, as an epic line of thunderstorms approached from the west. In Kansas City, Missouri, part of the roof at its downtown airport collapsed and traffic controllers had to evacuate from the tower cab.
The strong winds reached the Great Lakes, with Lake Michigan creating waves as high as 15 feet in some areas.

Multiple highways closed down in Kansas, where high winds and dust storms caused brownout conditions and reduced road visibility. The high winds, which reached 100 mph in some areas, blew roofs off houses and toppled semitrailers.
And over 166,000 Kansas homes and businesses served by Evergy, the state's largest electrical company, were without power as of 4 p.m. Wednesday, the company reported on an online outage map it maintains.
Already Wednesday, a gust of 107 mph was reported in Lamar, Colorado. The Colorado Springs Fire Department said on Twitter that they had received 635 calls for service within five hours — including one about the roof being blown off their own headquarters.
A Weather Service forecast office in Nebraska warned that "travel will be difficult, especially for high-profile vehicles. Trucks may be blown over. Holiday decorations will be damaged or blown away."
Some schools in Nebraska canceled in-person classes and dozens of schools in Iowa planned to close early Wednesday in anticipation of bad weather. Iowa State University in Ames, Iowa, shut down at noon due to the storm threat.
Over 48,000 Iowans were left without power Wednesday night, gas and electric provider MidAmerican Energy tweeted, and restoration could take up to three days due to extensive damage.
At this time of year officers in Iowa are used to warning people to stay off the roads because of snowstorms, not thunderstorms, said Polk County Sheriff’s Lt. Ryan Evans.
"It's really weird," Evans said. "We're 10 days before Christmas and we're talking about 70-degree temperatures and near-hurricane force winds."
Allan Curtis, a meteorologist with the National Weather Service in Des Moines, Iowa, said Wednesday's storm line would "raise eyebrows" even if it happened in the summer, he said.
“We don’t have a lot to compare it to,” Curtis said. “It’s really one of a kind for this state or this area for this time of year."
Des Moines police said on Twitter that no significant damage, injuries, or road closures had been reported yet as of Wednesday evening.

"Widespread damaging wind gusts (80+ mph) and a few tornadoes (some strong) are likely."
A tornado watch was in effect for portions of Kansas, Nebraska, Missouri, Iowa and Minnesota.
The Weather Service also predicted that daily high temperatures will skyrocket to over 30 degrees above average on Wednesday throughout the Plains and Mississippi Valley. "With spring-like highs anywhere from the 50s and 70s in the forecast, over 50 daily high records stand to be broken on Wednesday," the Weather Service said.
Ottumwa, Iowa, soared to 75 degrees on Wednesday, which was a state record high for the month of December.
The weather across the central states followed a powerful storm on Monday and Tuesday that socked drought-stricken California with heavy rain at lower levels and up to 6 feet of snow at some higher elevations.
