Much of Wyoming went about a month without seeing snow, with the main gap being between a mild system in early November to the most recent one this past weekend. That has completely changed this week as two systems have already hit (including the one this past weekend) and another is moving in from the west tomorrow. For the part of the state west of the continental divide, this will be arriving tomorrow morning and hanging around through much of the afternoon. The rest of the state will not see it arrive until late Thursday evening and into Friday morning.

The system will actually come in two waves: the first from the west and the second from the north. The one from the west will remain west of the continental divide for the most part. Rawlins will likely be the city farthest east that gets hit with this one, and it will be moving into the region early Thursday morning and sticking around most of the day. The second wave will be coming form the north, and that one will begin to impact locations such as Sheridan well after the sunset tomorrow evening, likely around the 9-10 PM hours. Casper will likely see this arrive shortly thereafter, just before the midnight hour and hanging around through the night and into Friday morning. This likely will not reach Cheyenne until after the sunrise Friday morning and should hang around until lunchtime Friday before clearing out.

Snowfall amounts for this as of now are not very impressive, as the spots forecast to receive the most will only see up to about 5 inches. That would be cities such as Jackson. Most locations will see between 2 and 3 inches west of the Divide, and east of it most locations won’t even receive an inch. Casper and Rawlins look to be exceptions as of now: Casper looks to receive between 2 and 3 inches and Rawlins between 1 and 2. Cheyenne will likely receive less than half an inch, and Laramie approximately half an inch. Things will then rapidly warm up over the weekend as powerful winds take over the state, especially come Sunday.
