Freezing rain and drizzle that froze on contact with the ground made driving conditions hazardous Sunday, and the roadways won't be much better Monday morning until the sun comes out.

"It has been so cold there is a layer of permafrost below the roadways," meteorologist David Sheets said Sunday.

Despite the temperatures getting to 32 or slightly above on Sunday, the freezing mark meant nothing. 

"Any moisture that touches the ground is freezing," Sheets said. 

Until the roads are salted and the sun is out Monday sending temperatures into the middle 30s, people can expect slick roadways with the potential for black ice.

Sheets said the sun could be out and shining by mid-morning. 

The high temperature is expected to reach about 34 or 35 degrees but the mercury will fall back into the middle and upper teens Monday night. 

Area police and the weather service are warning drivers to take it slow on their way to work Monday. 

The roadways were so slick Sunday that law enforcement throughout the Quad-City region were sending notifications out asking people to stay home, if possible.  

City, county and state authorities handled crashes throughout the day Sunday and into the night.  

Moline Police Detective Michael Griffin said that by 6:30 p.m. officers there had dealt with 18 crashes, but reported no serious injuries. 

Davenport police said they were busy throughout the day while handling four crashes at once at about 6 p.m. 

"Our officers have been busy all day," Rock Island County Sheriff Gerry Bustos said. 

"People need to stay off the roadways as much as possible," he said. "Wherever people are thinking of going and that it is important enough to get out and drive, well, it's not that important. 

"Your safety is more important than whatever it is you're going out for," Bustos added. 

Illinois State Police and the Illinois Department of Transportation sent out notifications discouraging noncritical travel because of icy roads.

In a news release, Illinois DOT officials said the icy weather would make travel treacherous throughout the evening and overnight hours.

Police had received a large volume of calls about crashes and vehicles in ditches, according to a news release issued Sunday from Illinois State Police District 7.

Police were "strongly discouraging" tow operators from attempting to pull vehicles from ditches, urging them to wait until the weather improves.
