1ST TOPIC:
Snow is still on track to nose into WY as early as Friday Afternoon for West of the Divide and approach SW WY by evening. As for Riverton/Casper, we could start see the snow showing up around the late evening hours approaching Midnight time frame. Snow continues Saturday Morning and through the Overnight. SUNDAY, we'll see a new Developing Low from the North in MT and drop South giving us a reinforcing shot of Snow for the Bighorns and Central WY.
2ND TOPIC:
I mentioned earlier tonight about 'THUNDERSNOW' potential. It is common to have this in placed for us during these situations. We'll stay quite mild/dry for Friday, but that Low will come through with a layer of Cold Air mixing in with Instability. Isentropics, or moisture running over ontop of Moisture will work in for Sweetwater County area and thats why they may see over a Half-Foot of snow.
Just what does THUNDERSNOW sound like? Here is a great clip from TWC's Jim Cantore having fun out in it:

3RD TOPIC:
Here are the Snow Amounts I posted earlier Tonight. BUT, looking after tonight's model data, I may need to lessen the projected Amounts.
4TH TOPIC:
Winter Storm Watches are out for much of Central WY & Includes the WY and Salt Ranges, plus the Wind Rivers.
Previously, I said 'LESSER' Snow amounts, here are tonight's Meteograms from CASPER and Riverton.
