Wider weather episode

The combination of ample Pacific moisture, good upper level divergence and an approaching Arctic Front brought heavy snow to many portions of western and central Wyoming. The heaviest snow fell in the western Mountains where many locations eclipsed 2 feet of new snow, with the highest amount of 32 inches at Lewis Lake Divide in Yellowstone Park. Meanwhile, East of the Divide, the heaviest snow fell around the Cody area, where over a foot of snow was common. The snow was accompanied by gusty winds that brought blowing and drifting snow that closed many roads for a time, including Interstate 25 in the vicinity of Casper.
