Utah Daily Snow
By Evan Thayer, Forecaster Posted 2 months ago December 9, 2023
Our storm is over and we have some hefty totals. Cold air is in place as high pressure gradually takes control this week. We have at least a week of mostly dry weather ahead.
Short Term Forecast
Significant totals reported today with another 14-17" reported in Little Cottonwood Canyon with, which makes about 2 feet in 36 hours and up to 28" since Thursday morning. BCC with a bit less, seeing totals of of 23" since Thursday AM. Beaver Mountain also picked up close to two feet from what I can gather, although they weren't reporting yet. Snowbasin and PowMow were in the 12-15" range. Park City with 16" since Thur and 11" for DV. Sundance saw less with just a few inches.
Overall, another very good storm. Alta-Collins is now at nearly 75" so far in December. We average just a touch less than 100", we are more than 75% of the way there but only a third of the way through the month.
Unfortunately, we are going to see a much drier pattern develop henceforth. Early in the upcoming week we will have some storm energy pass just to the north of Utah bringing light snow to areas like the Tetons. We could see some clouds and perhaps a few light snow showers, but likely no real accumulation.
The ridge builds stronger later in the week and we should be high and dry with warming temps aloft. Inversions are also likely. Looking at the long range, the only real chance I see for a storm is around December 18th. This is much more prevalent in the European model suite than anything else. Here is the EPS meteograms showing that most of the ensembles show at least something around Dec 18:
We will have to watch and see how this develops.
Way out in fantasyland, the models are showing remarkable agreement regarding a strong zonal jet stream developing across the Pacific. This happened at times last winter and let to some significant storms in the west. Of course, we'd have to see this jet continue to progress eastward into the western US. For now, all we can say is that this may provide the impetus for a pattern change for the latter part of December. At this point however, who knows?
