Storms returning to Utah with the first one slated to move in on Sunday into Sunday night. Monday powder day! A break later next week with another storm for next weekend (March 12/13).
Not a lot of change from yesterday’s forecast. Storm pushes in by midday Sunday with snow likely in the mountains. Snow levels will start out high Sunday morning (7k-7.5k) but quickly crash down to 5000 feet or so and should not be an issue. I still think that as long as timing holds, last chair Sunday should be good, but first chair Monday is prime time.
The 12km NAM is now fully within range and shows the following snow amounts for the Upper Cottonwoods:
This supports yesterday’s forecast of up to a foot for the Cottonwoods. Park City resorts and other resorts will likely be in the 4-8″ range. GFS is still more bullish on moisture than the Euro, but they’re closer today than yesterday so I think .5-1.25″ inches of liquid storm total is generally the range we’ll see in the Wasatch.
Looking at a map of this storm, we can check out the WRF-GFS composite from our friends at the University of Washington:
For some stupid reason I cut off the legend of this map and I’m too lazy to re-crop it. The yellow colors in the Sierra show 3-4+ feet of snow over the next 84 hours!!!! We talked about how good these storms will be for Cali a couple days ago, so no surprise, but still impressive. For Utah, the pink colors show areas with 6 inches or more of snow. The darker pink areas over the Cottonwoods show up to a foot of snow — in line with the forecast above.
Overall, not a huge storm for Utah but certainly not bad. Powder should be available. A chance for a few lingering showers on Tuesday, then we clear out for Wednesday-Friday with mild temps in advance of the next system.
Next storm pushes in next Saturday according to both the GFS and ECMWF. At this time it looks to be another moderate storm, but of course, this is 8 days out and a lot can change. Both models indicate a chance for an additional storm or two after that around mid-month.
