What happened
The episode as NWS FGZ wrote it up.
A strong winter storm slowly began moving across Arizona begining the evening of January 11th. By the time the storm moved into New Mexico on January 12th...it left as much as two feet of snow in its wake. Some of the snow totals are as follows: Mormon Lake 24 inches, Williams 21 inches, Munds Parks and Parks 18 inches, Flagstaff 16 inches, Grand Canyon Airport 15 inches, Jacob Lake 10 inches, Prescott and Seligman 9 inches, Forest Lakes 9 inches, Heber 7 inches, and Sedona 7 inches. Some private schools and all public schools in Flagstaff and Williams were closed due to the snow. DPS closed the northbound lanes of I-17 from the Sedona exit to Flagstaff until plows could clear the snow off. Chains were required for southbound traffic. A truck overturned and snow covered roads caused slow traffic on westbound I-40 near Ash Fork. About 1,600 Arizona Power Supply customers in the Iron Springs area were affected by a temporary power failure that was caused by the snow.
