Heavy snow hit the Midwest and Great Lakes over the extended Thanksgiving weekend, complicating the already busy time for holiday travelers and dropping a foot of snow in parts of Iowa and southern Wisconsin.

Chicago set a record for the most snow on any November day, with 8.4 inches on Saturday, more than half its total for the entire 2024-2025 season. Madison, Wis., also received its heaviest November snow in one day, with 9.3 inches on Saturday.

In St. Louis, the local zoo and Gateway Arch closed Saturday, when 6 to 8 inches of snow fell across the city.

Callender, Iowa, recorded the highest snowfall total of 16.5 inches.

The storm spelled trouble for those returning from the holiday weekend. On Interstate 70 in Indiana, 45 vehicles piled up in the snow Saturday afternoon. Eleven people were injured.
