A strong Pacific storm system will move through Northern Arizona producing widespread rain and snow. Moderate to locally heavy snow accumulations are possible at elevations above 6000 feet with some snow accumulation possible as low as 4000 feet. Expect winter driving conditions with slick roadways and low visibilities due to snow and blowing snow.

Storm total snowfall of 8 to 12 inches is possible at most areas above 7000 feet with locally higher amounts. Two to 4 inches is possible at 5000 foot elevation.
