The National Weather Service's Weather Prediction Center said the storm system will move over the Rockies and into the Northern Plains by Wednesday night, bringing heavy and wet snow to the region.
South Dakota is expected to experience the heaviest snowfall, with travel predicted to be “difficult to impossible” based on wind and visibility.
As of early on Wednesday, blizzard warnings had been placed in effect in 6 states, stretching from Colorado all the way up to Minnesota, according to Fox News Senior Meteorologist Janice Dean.
