The storm system that slammed much of the middle of the country over the Thanksgiving holiday weekend was winding down Monday, but a new system gathered over the northern Plains, centered over South Dakota and southern Minnesota — including the Twin Cities of Minneapolis and St. Paul.
While much of the country was clearing, in that area, "we've still got plenty of moisture to work with and certainly a lot of cold air," said Danielle Banks, a meteorologist for The Weather Channel.
Eight inches of snow had accumulated in Sioux City, Iowa, by 4 p.m. (5 p.m. ET) Monday, while 6.1 inches of snow was recorded in Sioux Falls, South Dakota, by midafternoon.
The Minnesota State Patrol said it had responded to 145 crashes in metro Minneapolis-St. Paul area by 10:30 a.m. (11:30 a.m. ET) as blowing snow reduced visibility to lass than a half-mile in some areas.
The region was under a winter storm warning Monday night from Pierre, South Dakota, south to Omaha, Nebraska, and east to just south of Minneapolis.
