A winter storm causing chaos on a busy travel weekend will bring more high winds and snow Monday as it pushes from the Midwest toward the Great Lakes.
More than 1,000 flights in the US were canceled Monday morning, according to FlightAware.com. More than 10 million people are under a blizzard warning due to the wintry conditions.
Chicago's O'Hare International Airport was hit particularly hard, with more than 800 flight cancellations and delays averaging more than 40 minutes because of heavy snowfall Monday morning.
The snow is causing travel nightmares for people like Michelle Hammar, a student at William Penn University in Iowa who turned 21 while stuck at O'Hare. She had three flights canceled so far, and sipped her first legal alcoholic drink at an airport bar.
Almost 200,000 are without power in Illinois alone, most in the Chicago area. More than 50,000 are out of power in Michigan, Indiana, and Wisconsin.
The storm brought heavy snow from Colorado and Wyoming, where up to 60 inches of snow fell, through the Midwest, including Iowa, which got up to 17 inches.
As the storm moves to the Northeast, more delays are likely. In all, winter-weather watches, warnings and advisories that stretch from Illinois to New England cover more than 18 million people.
The heaviest snow on Monday will start in Michigan and gradually work its way into New England. Temperatures have warmed in the Northeast, so rain is expected for the major metro areas. About 24 million people are under flood or flash-flood watches, including residents of New York City and Philadelphia.
Cold air moving in behind the storm will bring heavy lake-effect snows, with up to 20 inches expected just south of Buffalo tomorrow into Wednesday.
Kansas declared state of emergency
Kansas Gov. Jeff Colyer issued a state of emergency declaration for the state and officials said road conditions were "treacherous" in some areas.
"We strongly recommend that you postpone travel plans, if possible; however, if you must be on the road, make sure your vehicle's emergency kit is stocked, your gas tank is full and your cell phone and charger are with you and someone knows your travel plans," the declaration reads.
Kansas City International Airport was closed to flights arriving on the airfield due to low visibility caused by weather conditions but reopened Sunday evening, according to its Twitter account.
More than 1,700 US flights were canceled Sunday, with delays to 5,091 flights, according to flight-tracking website FlightAware. Most were at Kansas City and Chicago's O'Hare International and Midway airports.
Multiple roads were also closed because of whiteout conditions, according to the KanDrive website. The Kansas Department of Transportation tweeted late Sunday that Interstate 70 had reopened statewide but that there could be morning delays, with ice and wind blowing snow over just cleared highways.
There were reports of snow as high as 16 inches in parts of Iowa, with other areas reporting 3 inches to 10 inches. Baileyville, Kansas, notched 10 inches and 7 inches fell in Salina, Kansas.
The weather system was forecast to move into the Great Lakes region before hitting the Northeast on Monday, according to CNN meteorologist Haley Brink.
More than 10 million people are under a blizzard warning.
Nearly 20 million people were under a high-wind advisory. This includes residents of Kansas and some in parts of Missouri, Nebraska and Iowa. Wind reports from the Central Plains clocked wind gusts at tropical storm force from 50 to 75 mph from Nebraska to Texas.
Fort Hays State University student Brooks Barber captured the blizzard conditions in Hays, Kansas, on Sunday morning. Streets were dark, and many were without power, he said.
The National Weather Service Quad Cities office posted a video of a weather balloon being released in a blizzard.
Whiteout conditions brought low visibility to the small town of Chariton, Iowa, which is an hour south of Des Moines.
More snow coming
By Monday morning, many areas from the Plains to the Midwest will have seen 6 to 10 inches of snow, CNN meteorologist Michael Guy said. As the low pressure passes, areas behind the system will continue to see more snow through Monday evening with up to a foot possible before the skies clear.
Parts of Michigan, the eastern shores of Lake Erie, as well Maine could see up to a foot or more of snow before the storm exits the US by Wednesday morning, Guy said.
The major metropolitan areas in the Northeast will see wind and rain Monday into Tuesday. Wind gusts from 30 mph to 45 mph are possible as the system passes and temperatures drop through midweek.
