As Arctic air pushes southward across the Great Plains through Friday, a swath of snow and ice will do the same and continue to create slippery travel from Minnesota and Iowa to parts of Texas and Oklahoma.
According to FlightStats.com, more than 500 arriving and departing flights have been delayed and more than 30 flights have been canceled at Denver International Airport Thursday, many due to snow-related issues.

Roads and highways, including I-25, were slick and dangerous due to the snow around the Denver area early Tuesday.
The arrival of the Arctic air will erase temperatures in the 60s and 70s and replace them with temperatures in the 20s and 30s in a matter of hours across much of the Plains.
Many major highways will be adversely affected by the snow and ice, including I-20, I-25, I-35, I-40, I-70 and I-80.
The greatest amount of snow will fall from the mountains of Colorado and northern New Mexico, where 6 to 12 inches of snow are forecast.
In most areas, a heavy amount of snow and ice is not expected. However, even a small amount of snow and ice can create dangerous travel conditions, when combined with plunging temperatures.
For example around Denver, while only a few inches of snow are forecast, temperatures have dropped quickly during the snow, reaching the teens. As a result, any untreated surfaces made wet by the snow initially froze.
Other cities in line for snow include Omaha, Neb.; Colorado Springs, Colo.; and Dodge City, Kan.; Thursday into Thursday night. Around Albuquerque, N.M., most of the snow will fall on Friday, but it could begin sooner in the heights.
A wintry mix of a bit of snow, sleet and freezing rain are in the offing Thursday night into Friday for Des Moines, Iowa; Kansas City, Mo.; Wichita, Kan., and Amarillo, Texas.
Areas as far south and east as Oklahoma City and Tulsa, Okla.; Abilene, Texas; and Roswell, N.M.; could get a dangerous thin glaze of ice Friday.
Plain rain and drizzle will fall farther south and east from San Antonio, Texas, to Little Rock, Ark., and St. Louis. However, thunderstorms in parts of South and coastal Texas can be locally heavy. Where downpours persist there can be isolated incidents of flash flooding.
A late-April snowstorm dumped over a foot of heavy, wet snow across parts of Colorado on Thursday into Friday, boosting snowpack for an extended ski season at local resorts.
