Dropping overnight temperatures and icy breezes were expected to bring frost to the valleys Tuesday and snow to Utah's mountains by late Wednesday.
The National Weather Service issued a Hazardous Weather Outlook covering the western two thirds of Utah. Winds building to 25 mph and gusting in places well beyond that were to usher in the storm system on Tuesday. By Wednesday night, snowfall was expect to accumulate in all the state's mountains at 7,000 feet elevation and above.
Weather preceding the storm system will be breezy but warm. Temperatures along the Wasatch Front on Tuesday were expected to reach highs in the upper 60s, down from Monday's highs. Overnight lows were to be in the upper 30s and low 40s.
