This week's historic May snow followed the classic pattern of rare midspring snows — along a tightly defined line where atmospheric conditions were just right.
The Wednesday and Thursday snow traveled a northeasterly path, from southeast Nebraska toward Duluth, Minn. The heaviest amounts fell in north-central Iowa and in Minnesota.
As the storm spins and wobbles in the Midwest, snow is continuing to fall in areas where temperatures are low enough.
A number of maps have been created to depict the Wednesday-Thursday snowfall totals:
• Regionwide interactive map published by the Twin Cities office of the National Weather Service.
• Eastern Nebraska and western Iowa snowfall totals published by the National Weather Service/Valley.
• Iowa statewide map published by the Iowa Environmental Mesonet, a function of Iowa State University.
• National before/after map published by the National Operational Hydrologic Remote Sensing Center. To see how the snow cover changed before and after, enter April 30 and May 2 in the query box.
