A wet Saturday is forecast for north Utah: Light valley rain and mountain snow in the far northern part of the state on Saturday morning will spread south and increase in intensity throughout the day, the National Weather Service predicts.

A winter storm warning for the Wasatch and western Uinta ranges will be in effect until 9 a.m. Sunday. Snow will continue to fall Saturday night, then taper off Sunday morning, according to the weather service. Additional accumulations of 10 to 18 inches are predicted.

Winter driving conditions will impact mountain routes periodically, including Interstates 80 and 84, and blowing and drifting snow could reduce visibility, especially on U.S. 89 over Logan Summit, the weather service says. Drivers are encouraged to keep a storm survival kit in their vehicle.

The Utah Avalanche Center has issued a backcountry snowslide warning — in effect until 6 a.m. Sunday — for the Wasatch Range near Logan and the Bear River Range. Both human-triggered and natural avalanches are "certain" and skiers and others should stay off of and out from under slopes steeper than 30 degrees.

On Saturday, highs along the Wasatch Front will be mostly in the 40s and could reach 50 in a few areas, the weather service says. Sunday will be slightly cooler, with temperatures topping out in the mid 30s to about 40.

Skies in southern Utah will be partly cloudy over the weekend and highs are predicted to reach the upper 50s.
