In Phoenix, the overnight low was 30 degrees for the first time in five years and more cold temperatures were expected Thursday. The Tucson area saw as much as 6 inches of snow. Snow fell and stuck Tuesday on a desert highway over a mountain just 20 minutes outside Sin City. The cold weather and snow is “quite uncommon” for the area, said Glenn Lader, a National Weather Service meteorologist in Tucson. Nogales, an Arizona city on the Mexico border, had about 6 inches of snow, he said.
