The Minnesota Department of Transportation closed Interstate 94 between St. Cloud and the North Dakota border Sunday morning after 55-mile-per-hour winds created whiteout conditions. Minneapolis-St. Paul International Airport canceled 487 flights by 11 a.m. local time, stranding an estimated 42,000 travelers. Delta Air Lines spokesman Anthony Black confirmed the carrier grounded 214 of its flights, affecting routes to Chicago, Denver and Atlanta.

Xcel Energy reported 67,000 customers without power in Minnesota, while Wisconsin Public Service lost service to 22,000 homes.

Restoration efforts will begin once winds drop below 35 miles per hour, which meteorologists predict will happen Monday morning.

The same storm system that dumped 18 inches of snow on Duluth has spawned severe thunderstorms across the South.

Temperatures in the terminal dropped to 58 degrees after the airport lost partial power for three hours overnight.

The weather system will bring freezing rain to Michigan's Upper Peninsula by Monday morning, according to National Weather Service meteorologist Brian Adam.
