Its not uncommon to get brief impulses which pass through the cold air in the lower elevations and generate brief periods of snow; this is just such an event. It was captured just as I was leaving Talkeetna on the Spur around 12:55 AKST on Monday, December 23rd. Three of these bands of snow eventually deposited 1.5″ of snow in Talkeetna and 0.8″ of snow at my place on Mile 7.1 of the Spur.
