Early November has seen the most widespread snow cover in the Rocky Mountains, northern Plains, Great Lakes, and northern New England in at least two decades.
The National Oceanic and Atmospheric Administration said that 17.9 percent of the Lower 48 states had snow on the ground as of Wednesday morning.
On Halloween, snow fell from the eastern part of Minnesota to the western part of New York.
In some places, such Minneapolis, Milwaukee, Muskegon, Michigan, and Buffalo, there was enough snow to need shovelling.
Cleveland and Akron, Ohio, as well as areas downwind of Lakes Erie and Ontario, were covered early Wednesday, and several inches.
A week ago, the Mountain West, the northern Plains, the Midwest, and northern New England were hit by two separate storm systems, each of which delivered snow.
A strong early-season outbreak of cold air allowed for the present amount of snow. On Halloween, it delivered record low temperatures to the northern Plains.
