A dangerous blizzard that can close major interstate highways is heading for the Plains and the Upper Midwest Tuesday night into Wednesday.
The combination of plunging temperatures, high winds and over a foot of snow can leave unaware motorists stranded on Interstates 35, 79, 80 and others.
The powdery snow will be pushed around by 40-mph sustained winds leading to huge drifts that will challenge road crews to keep up.
The strong winds from the storm will create subzero AccuWeather.com RealFeel® temperatures in many areas. Frostbite can develop on exposed skin in minutes.
The heaviest swath of snow will stretch from Omaha to Des Moines to Madison. However, many other cities over the region including Chicago, Milwaukee, Kansas City and Minneapolis will have either substantial snow or a wintry mix and most importantly travel delays and dangers.
Travel and outdoor exposure for long periods of time should be avoided in the core of the storm's wind and snow.
If you must travel by ground through the storm, make sure you and your vehicle are winter ready. Throw a shovel in your car, pack extra blankets and make sure your cell phone is charged.
Expect substantial flight delays and cancellations at midweek not only from Chicago to Denver, but also ripple-effect problems across much of the nation.
The most substantial lake-effect snow event of the season so far following the storm will bury some communities that escape the front end blizzard.
As a result, some areas could be buried under feet of snow as the "December to Remember" continues.
