The Bridger-Teton Avalanche center currently has avalanche danger as Moderate to Considerable across their forecast areas. According to the Bridger-Teton Avalanche Center, "The snow that came in with high densities over the month has settled and the snowpack has gained significant strength [across most of the Tetons and in the Wyoming and Salt Ranges]. The exception to this is the Togwotee Pass area where the poorest snowpack structure still exists. Yesterday a snowmobiler remotely triggered in that area on a south facing slope." There was a recent death just east of Togwotee Mountain Lodge earlier this month. So please be aware of the danger if you are going out into the back country as more snow will certainly not make conditions any safer.
Another impact this storm will have will be on livestock. It is calving season, and these colder, wet conditions could have a significant impact on vulnerable new calves. Particular care will need to be given to those that are born today when the snow will be at its heaviest. A stiff northeast wind at 10 to 20 mph will accompany the snow across much of northern and central Wyoming, and temperatures will drop to around zero degrees. Some areas of the Big Horn Basin could drop well below zero. Tonight and Sunday morning will be very cold as well, although winds will be lighter and snow will be very light to non-existent across the low elevations east of the Continental Divide.
Roads and passes across western and central Wyoming could have restricted travel or could close during this winter storm.

The heaviest snow fell between South Pass and Muddy Gap overnight. Snow is expected to be heavy across Natrona and Fremont Counties early this morning, with the focus shifting north and west toward mid morning. Light snow will be possible through the day, with another disturbance moving through this evening, some more moderate snow will be possible but the best dynamics have passed. Rain will continue to be possible across the south, and some of the southwestern valleys. The rain/snow mix will eventually turn into all snow once the front is able to push through the southwest flow this afternoon. All areas should see decreasing snowfall and improving conditions by late this evening.
In addition, a secondary surge of arctic air will continue to plunge south allowing temperatures east of the Continental Divide to drop to the low single digits or even below zero this morning. High temperatures will struggle to climb above zero across the far north, with only single digits to low teens in Fremont and Natrona counties.
