A blizzard threatened to dump more than a foot of new snow and snarl traffic for millions of people across eight states in the midwest on Tuesday.
NBC News reported that the storm is likely to span from Nebraska and Wyoming to southeastern Wisconsin after moving out overnight from Colorado.
As forecasts on the storm came in, more than 525 arrivals and departures were canceled Monday at Denver International Airport as the city was forecast to get up to 14 inches, according to the National Weather Service.
"This storm has the potential to affect thousands of people," said Rachelle Lipker, executive director of the Red Cross in central and western Nebraska.
