2015-11-25 to 2015-11-26 · Upper Green River Basin, Wyoming

Event narrative

Snowfall of 6 to 8 inches fell in Big Piney/Marbleton northeast along the Green River.

Wider weather episode

A storm moved out of the northern Great Basin and slowed down as it moved through Wyoming. This resulted in a rather prolonged period of snow that hampered Thanksgiving Week travel. Moisture overran a dome of cold air in place across central Wyoming and enhanced snowfall across Fremont and Natrona counties. The heaviest snow fell in the areas favored by north to northeast upslope flow, generally along the east slopes of the Wind River Mountains through the Lander Foothills and east to around Casper. Snow amounts of around one foot were common in the vicinity of Lander with totals of at least 14 in the mountains above town. Other locations with heavy snow included the Wind River Basin where 6 to 10 inches of snow fell and south of Casper where 6 to 8 inches was measured.
