May snowstorm rumbles on over Plains, Upper Midwest

The middle of the country is experiencing May snowfall records in what seems to be a never-ending winter. The Weather Channel's Mike Seidel reports.

A rare May snowstorm that's hit the Plains and Upper Midwest was expected to continue into Friday and even Saturday in places, the National Weather Service said.

However, it added that the “rather unusual weather pattern” was “beginning to abate over the Upper Midwest.”

A number of winter storm advisories were in place early Friday for parts of Missouri, Montana, Michigan, Wisconsin, Minnesota, Iowa, Wyoming, and Oklahoma.

The worst affected areas in the mainland U.S. -- southern Montana and northern Wyoming -- could see 5 to 9 inches of snow from Friday morning to the time it finally stops early Saturday evening.

The weather service said the other areas could see anything from freezing rain and sleet in northwestern Michigan to up to 3 inches of snow in northeastern Oklahoma.

There was also a winter weather notice for Alaska, where Denali National Park and other areas could see up to 10 inches of snow.

The weather service said “widespread showers and thunderstorms” were expected to develop over the Deep South and into Florida through the end of the week.

“Rainfall amounts of several inches are possible where heavy rain persists the longest,” it said.

On Thursday, weather.com reported that the storm had "dumped up to 13 inches of snow in Owatonna, Minn.,” while up to 14 inches of snow was measured in Ellsworth, Wis. Up to nine inches fell in Dodge County, Minn., on Thursday.

In some parts of the country, spring still feels far away. The snowfall in the Rockies, Plains and Dakotas is setting records and may not end until Friday. NBC's Brian Williams reports

“This is a record for me,” Brian Wagstrom, director of public works in Minnetonka, Minn., told NBC station KARE. “This is the latest that we have ever put plows on this time of the year.”

Jim Eulberg, director of public works in the South Dakota town of Worthington, had to tell his crews to give up spring street sweeping and ready the plows.

“When you’re looking at the calendar, you’re thinking this is the stuff we should be doing. Not dealing with ice storm damage and plowing,” Eulberg told NBC station KDLT.
