Halloween was certainly an eventful day weather-wise for Chicago.
After the city registered its first-ever measurable Oct. 31 snowfall on record earlier Friday, high waves and flooding on account of heavy winds caused city officials to shut down part of the Lake Michigan-adjacent Lake Shore Drive in the afternoon.
As winds gusted above 70 mph Friday afternoon -- part of what a WGN meteorologist has dubbed the "Halloween Howler" -- northbound lanes of Lake Shore Drive were shut down between North Avenue and Division Street, CBS Chicago reports.

The stormy weather has also meant delays and cancellations at O'Hare International Airport. According to the Chicago Tribune, more than 300 flights were canceled through noon Friday, with more cancelations and delays anticipated. No cancellations or delays were reported at Midway International Airport.

Lake-effect snow is also possible in northwest Indiana and the far southwest Chicago suburbs, the Tribune reports.
