The storm was late in coming, according to the Salt Lake office of the National Weather Service.

The storm was expected about 5 a.m. Monday but had arrived early Monday afternoon in some areas and is expected to leave one to three inches of new snow in northwestern Utah valleys and one to two feet in the mountains by late Monday evening, said Bob Cox, a weather service specialist.Three to five inches of snow had fallen in some mountain areas by 10 a.m.

Cox said temperatures will drop behind the front to the mid- to upper 30s. He said the storm arrived in the Salt Lake Valley later than expected because a low-pressure area developed along the front in eastern Nevada. That slowed progress of the storm.

"It's hard to forecast the whims of Mother Nature when these areas of low pressure develop," Cox pointed out.

It was snowing in Cedar City at 9:50 a.m., and just minutes later at the Salt Lake International Airport and snow was reported in Dugway at noon. Winds at the airport picked up to 38 mph. During the morning, St. George recorded 59 mph winds; Cedar City, 45; Delta, 43; and Holladay, 33. Wind velocities reached 44 mph during the night at Hill Air Force Base.

Cox said snow showers are expected to decrease in the valleys but to continue in the mountains during the night. The forecast is for partly cloudy weather over the state Tuesday. Another storm trough, about the intensity of the present system, is expected to move in and out of the state Wednesday, Cox said.
