Travelers in Chicago faced significant disruptions on Sunday as hundreds of flights were delayed or canceled due to a winter storm affecting the Great Lakes region. The storm brought a mix of rain and snow, impacting travel plans for many returning home after the Thanksgiving holiday.

At Chicago O'Hare International Airport, over 250 flights had been canceled by early afternoon, with more than 1,000 experiencing delays, according to FlightAware. The Federal Aviation Administration reported that departures to O'Hare were delayed by nearly an hour on average, while departures from the airport faced delays of about 15 minutes, which were expected to increase as weather conditions worsened.

The storm also caused significant snowfall in the region, with areas near Lake Michigan receiving up to 12 inches (30 centimeters) since Saturday. Chicago O'Hare set a record for the highest single-day snowfall in November, recording 8.4 inches on Saturday, surpassing the previous record of 8 inches set in 1951.

In Wisconsin, utility crews worked to restore power to over 6,000 customers affected by outages, particularly in Milwaukee and South Milwaukee. Mark Paladino, a resident of Fredonia, shared on social media that his apartment complex lost power while he was shoveling snow. Reports indicated that power lines were sagging under the weight of heavy, wet snow.

The airport in Des Moines, Iowa, reopened after a Delta Connection flight from Detroit slid off an icy runway. Fortunately, no injuries were reported, and passengers were safely transported to the terminal by bus. Meanwhile, many churches in western Michigan advised congregants to stay home or attend services online due to the weather.

The National Weather Service noted that gusty winds in Iowa were blowing snow back onto roads, creating hazardous travel conditions. Meteorologist Andrew Orrison reported that some areas in Iowa and Illinois received over a foot of snow, including 15 inches (38 centimeters) in Fort Dodge, Iowa.

While snow in the Great Lakes region was beginning to taper off, a new storm system was forecasted to move toward the Mid-Atlantic and Northeast, potentially bringing up to a foot of snow by Tuesday. Orrison stated, "It’s going to be the first snowfall of the season for many of these areas, and it’s going to be rather significant. The good news is that it does not look like the major cities at this point are going to be looking at any significant snowfall."
