The crest-level flow today was out of the southeast. You can see this southeasterly flow in the 1700 UTC (10 AM MST) plot below, which shows southeasterly flow at the top of the Snowbird Tram, Mt. Baldy, and Top of Collins.
The influence of the orographic cap cloud was readily apparent while skiing in the morning and afternoon. Prior to about 11 am, snowfall was very limited and one could see the cap cloud hanging over Mt. Baldy and upper Collins Gulch from the Wildcat chair. In upper Collins Gulch, the light was quite flat and it was very windy. In contrast, on the lower mountain, the light was considerably better.
Late in the morning, snowfall began to increase as a larger-scale precipitation band moved over Little Cottonwood from the south. Snowfall was light, but clearly increased from the lower to upper mountain, at least through our departure at 3 PM. There can be many causes of such contrasts in snowfall, but I suspect crystal growth in the cap cloud that was embedded in the larger-scale cloud shield was a contributor.
The weather geek highlight of the day was provided by the ice crystals that were falling during the late morning, many of which were beautiful stellar dendrites. Oh it's great to see my stellar friends again!
