Light snow fell overnight and caused some issues on area roads and has impacted air travel, but nothing serious, according to the National Weather Service and Illinois State Police.
As of 10:30 a.m., airlines at O'Hare International Airport are reporting some delays averaging 15 minutes for inbound and outbound flights, and more than 45 cancellations Saturday, according to the city's Department of Aviation.
Airlines at Midway Airport have nearly half a dozen delays from 20 to 60 minutes but otherwise have normal operations, according to the aviation department.
A winter weather advisory remains in place until noon, and as of 6 a.m., O'Hare reported 0.4 inches of snow, according to weather service meteorologist Amy Seeley.
Near Midway, 0.3 inches was reported, and the highest snowfall for the area was in northwest suburban Spring Grove, where 0.5 inches of snow fell, according to the weather service. The next two highest totals were in the northwest suburbs - 0.8 inches in Buffalo Grove and 0.7 inches in Palatine.
As of 9 a.m., the snow had changed to rain or freezing rain in the Chicago area, with temperatures expected to stay in the mid-30s.
Overnight, there remains a chance of light snow and light rain, Seeley said.
"There are some reports of slick roads," she added.
The Illinois Department of Streets and Sanitation redeployed its snow plows and salt spreaders to neighborhood and side streets, according to a statement.
"Safety is the city's top priority, and motorists are urged to be patient when driving during inclement weather, to be cautious," the statement said.
A handful of weather-related accidents have occurred on Cook County highways, but nothing serious, said an Illinois state trooper.
"Mostly slide-offs," said the trooper, who added that officials are "doing a good job salting the roads."
The entire tollway system had numerous spinouts and accidents earlier this morning, said Illinois State Police Master Sgt. Paul Carlos. But it has warmed up, and "it seems like the accidents have slowed down," Carlos said.
"The warming temperatures have assisted in keeping the ice down, and the ice trucks have been out all morning," Carlos said, adding that no one was injured but cars were plowing into ditches and walls.
Farther south, the roads are "very hazardous," according to state police Master Sgt. Wilfredo Rivera.
"There's not a lot of snow, but the roads are very, very slick," Rivera said. "We have multiple vehicles in the ditch on I-55, I-57 and Route 102."
"Pretty much our whole district" is having problems, he said, though nothing involved serious injuries.
"They're hustling, it's the first snowfall of the season," Rivera said of workers clearing the roads.
The Elgin District had no road blocks and no weather-related problems, according to a state police spokeswoman.
