PORTLAND, Maine (AP) — Black ice, snow showers, and fog have created treacherous travel conditions for post-holiday travelers in the Midwest while the Northeast braces for its first major snowstorm of the season.

Chicago O'Hare International Airport received a record-setting snowfall of over 8 inches (20.32 cm) this weekend, the highest for a single November day since 1951. This resulted in the cancellation of approximately 300 flights and delays affecting more than 1,600 by Sunday evening. Commuting conditions on roads remained hazardous, with ongoing advisories until Monday night.

In the Northeast, forecasters predict that some parts of northern New England could see up to 10 inches (25.4 cm) of snow, while a windy and icy storm approaches the region. Preparations are being made as plow crews mobilize to tackle a snow-coated Pennsylvania Turnpike, with vehicle restrictions set for 5 a.m. Tuesday.

Officials report that over 600 equipment operators are prepared to clear the 2,900 miles (4,667 km) of roadways across the turnpike system. Winter preparations have been in place since mid-November, ensuring that crews are ready to respond to the winter weather challenges.

Travelers at O'Hare Airport expressed frustration as the delays persisted, with one 76-year-old retiree stating, It is what it is. It’s congested, but that’s expected due to the snow, the delays, and the holidays. Roads leading to O'Hare remained congested, adding to travel woes.

In response to the snow, the Federal Aviation Administration reported that de-icing operations were taking place at several major airports. Meanwhile, power restoration efforts continue in Wisconsin, where thousands experienced outages due to heavy snow.

Meteorologist Andrew Orrison noted that the mid-Atlantic and Northeast regions should prepare for significant snowfall by Tuesday, although major cities may escape the worst of the storms.

As this winter weather continues to evolve, travelers and residents alike are urged to remain vigilant and plan ahead for safe travel and adequate preparations.
