A ground stop has been issued at O’Hare International Airport due to the snowy weather conditions. The Federal Aviation Administration (FAA) halted all inbound flights at O’Hare just before 8 a.m. Friday.

Slick road conditions were expected to remain as 1 to 2 inches of snow has fallen throughout the city and surrounding suburbs Friday ahead of mix of snow and freezing rain Sunday, the weather service says.

Snow from a winter weather system in the southern part of the U.S. had moved into the Chicago area early Friday morning, with some parts expected to see a slippery rush hour commute, the NBC 5 Storm Team said.

Recently, an American Airlines plane and a United Airlines aircraft collided at the Chicago airport, which has stirred discussions on social media. Following the incident, both the airlines and official authorities released multiple statements explaining the details.

The plane left the Lehigh Valley International Airport in Allentown, Pennsylvania, around 5:24 a.m. and was expected to arrive at Chicago's O'Hare International Airport at 8:44 a.m.

United Airlines flight 4166 — from Pennsylvania to Chicago — made an emergency descent after rapidly losing cabin pressure 40,000 feet above Ohio.
