“Historic Snowstorm Potential for Omaha to Minneapolis,” reads the headline.

“The same storm bringing heavy snow to Denver and Cheyenne Wednesday … has the potential to bring a swath of heavy, wet snow from eastern Nebraska to northwestern Wisconsin and the western Upper Peninsula of Michigan.

In May!

“The upcoming storm, like many in recent weeks, seems to be ignoring the date. (It) could bring 6 inches to a foot of snow on its northwestern flank Wednesday night and Thursday over the central Plains into the Upper Midwest.”

“There have been some snowstorms in May in the region, but they are rare,” says MSN.

According to National Weather Service records, 2 inches of snow fell on Omaha on May 9, 1945. The only other snowfalls both came on May 3 in Omaha. One was 1.3 inches in 1907 and another was 1.0 inch in 1967.

The heaviest May snowfall on record for Des Moines, Iowa, was in 1907, when 1.2 inches fell on May 3.
