A blizzard came down out of the Rocky Mountains on Tuesday and blanketed much of the Great Plains with more than a foot of snow. Along with the snow there has been severe and extremely heavy winds with driving snow and rain as well as the threat of tornadoes.

The worst of this first major storm of the season looks to hit further east and south of Denver with over a foot of snow predicted for some areas, according to USA Today. On Tuesday, the blizzard with driving snow and heavy winds hit most sections of Colorado, Nebraska, Kansas, and New Mexico.

The Denver area is bracing for more than a foot of snowfall and most sections of Interstate 25 have been closed down. Plows can’t clear the snow from the interstate due to the high winds just blowing the snow back at the trucks and back on to the roads. In addition, the interstate is now plagued with a plethora of jack-knifed 18 wheeler semitrailers.

In the southwest part of Colorado, there are reports that over two feet of snow has already landed and the storm continues to bring more. On Tuesday morning, 145 flights in and out of Denver International Airport were either canceled or re-routed to other airports. Airport officials say the expect nearly two feet of snow to be dumped on the airport when the storm has finished barreling through.

The snow from the blizzard is also expected to reach the likes of the panhandles in Oklahoma and Texas as well as reaching into Wyoming. The storm is expected to clear through late on Tuesday night and begin its trek into the upper Midwest where it is expected to land come Wednesday morning.

Further south of the storm, heavy rains and severe thunderstorms are causing havoc and chaos as the storm also brings tornadoes with it. Dallas has already been hit and the thunderstorms stretch east into Louisiana and Arkansas. The severe rain and heavy thunderstorms are also expected to lash Mississippi and Missouri and the threat of severe flooding will be present.
