Late-Season Snow Moves Through Upper Midwest
UPDATED 3:15 PM CDT, April 18, 2013
UPDATED By WeatherBug Meteorologist, John Bateman
A late-season winter storm will continue to rage across the northern Plains and western Great Lakes, bringing another six or more inches of fresh snow today and Friday.
The heavy snow hitting Nebraska, South Dakota and central Minnesota is the result of a large low pressure system moving northeast across the central Plains and into the Great Lakes. On this system`s rear flank, cold air is streaming southward out of Canada. This will combine with Gulf of Mexico moisture to produce heavy snow as the storm progresses into southern Ontario by the end of the week.
Winter Storm Warnings and Winter Weather Advisories stretch from central Nebraska to the U.P. of Michigan, including the cities of Sioux Falls, S.D., Minneapolis and Duluth, Minn., and Marquette, Mich.
As the storm marches eastward, heavy snow will continue to be the main theme through Friday morning. Snowfall accumulations of 3-5 inches are expected across the High Plains of western and central Nebraska, with a wide swath of 6-8 inches or more expected from eastern South Dakota to northern Minnesota, including the Minneapolis-St. Paul metro area. Making matters even worse, gusty winds up to 35-40 mph will accompany this storm, causing blowing and drifting of snow that will reduce visibilities and make for hazardous travel conditions along Interstates 29, 35, 90 and 94.
This same storm has its origins in the central Rockies, where it already piled up impressive snowfall amounts across Colorado on Wednesday. Steamboat Springs reported 12 inches of new snow from this storm, with 11 inches piling up near Eldorado Springs. The town of Rye, Colo., picked up 10 inches of late-season snowfall.
