The Winter Weather is Back
December 10th, 2020
The weather pattern around Wyoming has completely shifted over the last 24 hours, with Wednesday being the warmest day of the week with plenty of sunshine shifting into today with plenty of cloud cover and much cooler conditions. The stage is set for the arrival of our next bout of winter weather, and for parts of Wyoming it has been awhile since any decent snow has fallen. There was a bit of snow in the middle of the state to kick off December, however none of that made it into Cheyenne. In fact, the last time Cheyenne got measurable snowfall this season was November 9th, or a full month ago.
That all changes tonight, as Cheyenne may be the spot in Wyoming that receives the most snow. It could also end up being Laramie or somewhere like Wheatland. With the system impacting the state from the south, the southeastern part of the state will likely see the most snow, with the only potential exceptions being the higher elevations along mountain ranges. As of now it is expected that snow will likely begin in Cheyenne sometime late this evening. It should be before the midnight hour, however the snow won’t get heavier until tomorrow in the morning/afternoon. For Casper, the snow will likely begin a little later than Cheyenne, and it should see most activity as well tomorrow during the morning and afternoon. That will end wave one.
Wave two looks to arrive Saturday, moving in from the southwest across the southern half of the state. This is likely where both Laramie and Cheyenne will receive the bulk of their snowfall, with places like Casper expected to receive minimal impact from this. With there already being snow on the ground, there will be no delay on accumulations as the second wave rolls through the southeastern part of the state Saturday afternoon and evening. When it comes to snow totals, both Cheyenne and Laramie will likely see somewhere between 4-6 inches, while Casper will likely not get more than 2. Keep in mind that Casper likely will not be impacted much at all by the second wave of snow; after wave one both Cheyenne and Casper will likely have about 1.5-2 inches on the ground. If things set up right, however, either location could get a little bit more.
Anticipate issues on I-80 beginning Friday morning thanks to snowfall during the overnight hours heading into Friday along the Laramie Mountain Range and through the Medicine Bow. There isn’t too much wind in the forecast as of now, however those may pickup a bit on Saturday when wave two rolls through, potentially leading to blowing snow and low visibility through the region along with snowy roads. There is a very large chance that I-80 will close at some point between Friday Morning and Saturday Night, maybe even for several hours.
