As of 1 p.m., the Utah Highway Patrol had responded to 110 accidents in Salt Lake County and another 52 accidents in Davis County, said Trooper Preston Raban. About a quarter of those crashes have resulted in injuries, he said, though none of them serious.

He attributes most of the accidents to driving too fast.

"People get confident in the way they are driving and hit that one spot and then they lose it," Raban said.

At the Salt Lake City International Airport, a snowy runway caused a United Express flight from Denver to be diverted to Idaho, a spokeswoman said.

The plane's 49 passengers then took a 225-mile bus ride to Salt Lake City after landing in Twin Falls, Idaho, at 10:24 a.m., said Robin Urbanski, a spokeswoman for United Airlines.

The plane, which had four crew members, was diverted while snow was being removed from a runway, she said.

Dida Hadley, an airport control center operations coordinator, said there were no other delays or diversions because of the weather.

Light snow is forecast to continue falling throughout the afternoon, with the majority of the storm moving south towards Utah County, said National Weather Service meteorologist Gene Vancor.

Commuters along the Wasatch Front can expect slick, slushy roads for the drive home, he said.

Accumulation forecasts range from possibly a foot in Dixie's southwest valleys, to up to 6 inches in areas of the northern valleys and up to 9 inches along the benches.

The good news is the weekend might be warmer than earlier predicted - yes, the National Weather Service says there's a possibility temperatures will stay above zero.

A snow advisory is in effect until 5 p.m. today for the Cache Valley, northern Wasatch Front, the Great Salt Lake Desert and the mountains of northwest Utah.

The weather service warns that snow will cause travel difficulties, and drivers should be prepared for snow-covered roads and limited visibility.

Pete Wilensky, the lead forecaster in the service's Salt Lake City office, said the snow could continue off and on through Saturday.

However, he said the Arctic air mass moving in from the North has "somewhat modified."

"We won't get bitterly cold - highs in the 20s, lows in the lower teens," Wilensky said. "We have a pretty cold air mass, but we have a lot of cloud cover to keep it moderated.

"I don't see us dipping below zero unless (the clouds) really clear out," he said. "The first chance of that happening is Saturday night, and that could be a slow process."
