"Increasing south winds ahead of a cold front could become locally strong in the southwestern valleys on Friday. This strong cold front will slowly cross the outlook area from north to south Friday through midday Saturday.
“Heavy snow will accompany the cold front with significant snow accumulation in the mountains, southwest Wyoming and the northern, western and central Utah valleys,” the alert states. “Even Utah’s Dixie may see some snow with this storm Saturday.”
Locally heavy snow showers will continue across the outlook area through Saturday night.
Persons planning travel anywhere in the outlook area Friday afternoon through early Sunday should be prepared for winter driving conditions in snow and allow for plenty of extra time to reach their destinations.
There is the potential for some additional snow across the northern outlook area Monday."
