CHICAGO - Residents across parts of the Chicago area woke up Monday to the season's first blanket of snow.

What we know:

The first snow of the season arrived late Sunday into overnight, with some areas seeing up to a foot.

Lake County, Kankakee, and northwest Indiana appear to be the hardest hit communities. Several school districts canceled classes or switched to e-learning.

Air travel also took a hit, with hundreds of flights canceled at both O’Hare and Midway airports. Some roadways also saw whiteout conditions, with wind gusts of nearly 60 mph reported.

Chicago’s first snowfall typically arrives later in the year. On average, the first trace appears around Oct. 31, measurable snow by Nov. 18, and the first inch or more by Dec. 7.
