Utah forecast: You've been warned winter's coming
Heavy snowfall and strong winds were expected through northern Utah until Friday morning, according to a Winter Storm Warning issued by the National Weather Service.
Valley rain was predicted to change to snow in the valleys by Thursday morning, tapering off by Friday morning.
A trace to 2 inches of snow on the valley floors Thursday will bring the possibility of slushy roadways during the morning commute, the weather service said.
In the mountains, anywhere from 10 to 20 inches could fall.
Winds took down power lines on the Wasatch Front and cause a blackout to about 4,800 customers near Bear Lake, according to Rocky Mountain Power. Gusts overnight were expected to reach 75 mph.
The Utah Avalanche Center issued an avalanche watch for all mountains of northern and central Utah, down to the Fishlake Plateau.
The really good news, though, is the atmospheric cleansing the storms bring. The Utah Division of Air Quality graded all areas of the state at "green," or healthy, beginning Thursday.
Salt Lake and Tooele counties looked for plentiful rainfall Thursday, with high temperatures around 40 degrees.
Southern Utahns had cloudy skies and a chance of rain, but otherwise enjoyed spring-like weather. Highs on Thursday were to range into the mid-60s.
