|A complex early season winter storm brought a variety of weather to the Cowboy State on Monday, October 28th. The Wind River Basin and west and southwest Wyoming were most impacted by this storm. Before sunrise Monday rain broke out across the Wind River Basin, but quickly turned to snow by the morning commute. Moderate to heavy snow occurred through the morning hours. By early afternoon much of the Wind River Basin had received 3 to 6 inches of snow with isolated higher amounts. The focus shifted to southwest Wyoming Monday afternoon as a strong line of thunderstorms along a cold front pushed east out of southeast Idaho and northeast Utah. Some damage even occurred in Kemmerer from strong thunderstorm winds. Temperatures cooled behind the cold front with rain changing to snow across much of southwest Wyoming during the early evening hours. Some persistent heavy snow showers set up in a north to south orientation generally from Jackson to Kemmerer from the middle of the evening through shortly after midnight. Around 8 inches fell in Jackson while around 4 to 5 inches fell around Kemmerer. Fog and freezing drizzle were also observed in some areas east of the Divide Monday night. All of this activity resulted in slick road conditions with South Pass even being closed Monday night into Tuesday morning.|
