Winter Storm Keeps Moving Eastward, Impacting Central Areas through Early Evening
A potent winter storm is impacting the region today. Winter Storm Warnings still in effect for Cody and Buffalo until 5 pm this evening. Winter Weather Advisories have also been issued for other areas of the state. Treacherous travel conditions with near zero visibility could occur along Interstate 80 Saturday morning when a heavy band of snow combined with strong wind is expected to track across the area (see radar simulation below). The snow has spread to areas east of the Divide. The heaviest snow is expected along Interstate 25 from Buffalo to Casper through Saturday afternoon. The snow tapers off or becomes very light across the west by early Saturday afternoon while the snow east of the Divide should exit the area late Saturday night. Windy conditions on Saturday could cause significant blowing and drifting of snow.
IMPACTS:
Western roads remaining slick and hazardous especially in the morning.
Interstate 80 could see white-out conditions Saturday morning from continued snowfall, and strong wind creating significant blowing snow.
Roads east of the Divide will gradually become slick in most locations. Travel will become difficult, especially along Interstate 25 between Casper and Buffalo by Saturday afternoon.
