"CHICAGO - A massive winter storm spreading across the U.S. West into the Northern Plains and Midwest on Tuesday could produce blizzards, brutal cold, and record snowfall, making road travel treacherous and disrupting air travel.
The National Weather Service issued winter storm, blizzard and high-wind advisories for a broad swath of the western and north-central United States. Up to two feet (61 cm) of snow and winds of up to 60 miles (97 km) per hour were expected in some spots from Tuesday through Thursday.
Snow falling at a rate of two inches an hour and gusty winds will make travel conditions treacherous and perhaps impossible in parts of the Northern Plains and the Upper Midwest, the service said in its forecast."
