All major roads in northern Arizona reopened by Monday morning after a strong storm swept through the region over the weekend.
State Highway 89A in northern Oak Creek Canyon and part of U.S. Highway 180 northwest of Flagstaff were closed because of heavy snow and icy conditions, but reopened Monday morning after Arizona Department of Transportation crews worked all night to clear them.
Northbound Interstate 17 north of State Highway 179 reopened late Sunday afternoon.
Prescott's official Sundog measuring site on the northeast side of the city recorded 4.5 inches of snow from the storm. Higher-elevation areas in the center of the city saw around 7 inches, while higher sites 3 miles southwest of Prescott reported 10 inches.
The storm started out colder than the Weather Service anticipated, with snow falling Saturday afternoon in Prescott instead of the forecasted rain. The snow continued into Saturday night and Sunday as forecasted, falling as low as 4,000 feet in elevation.
The heaviest snowfall accumulations in the state fell over the western Mogollon Rim and Kaibab Plateau.
Other snowfall totals reported to the Weather Service included 44 inches at the Arizona Snowbowl ski area near Flagstaff, 18 inches at Flagstaff and 4 inches in Seligman.
The storm produced the first precipitation for 2011 in Prescott.
The forecast is calling for a 10 percent to 20 percent chance of rain and snow in Prescott Wednesday and Thursday.
