I'm at the Salt Lake airport to do my duties as a principal investigator and suffer through a week on the east coast away from snow. The view this morning of the northern Wasatch was beautiful, with a spectacular lenticular cloud sitting right on the Wasatch crest.
Such a cloud pattern is consistent with easterly downslope flow, as are the low level cumulus clouds closer to the airport. Those clouds are likely forming in the updraft where the downslope flow experiences a hydraulic jump, similar to what occurs in some situations during water flow over a rock.
The easterlies are quite evident in the weather observations near the mountains and to the east.

That's probably for the best. Our snow safety teams need a break.
