The season's first snows have frosted the Rocky Mountains, the northern Plains, the Great Lakes and northern New England over the past week, resulting in the most extensive early-November snow cover in at least two decades.
On Wednesday morning, snow was on the ground in 17.9 percent of the Lower 48, according to the National Oceanic and Atmospheric Administration.
Locations from eastern Minnesota to western New York saw snow on Halloween — even enough to shovel in Minneapolis; Milwaukee; Muskegon, Mich.; and Buffalo. Areas downwind of Lakes Erie and Ontario were also blanketed early Wednesday, including Cleveland and Akron, Ohio, while several inches were anticipated along some of the west-facing slopes of the Appalachian Mountains.
This latest batch of wintry weather comes on the heels of two other storm systems that brought snow to the Mountain West, the northern Plains, the Midwest and northern New England over the past week.
