The upper-level low has closed off sufficiently that the flow has an easterly component. Nobody is happier than than those in the Park City area who are getting some of the white stuff this morning.
Alta-Collins had an 8" storm total on the stake as of 8 am, from only .54" of water. Upper portions of PCMR may have done a bit better. The Thaynes Canyon SNOTEL has 0.6" of water through 8 am and an increase in total snow depth of 7" (typically that underestimates the new snow depth due to compaction of the underlying snow).
A few hours of easterlies can do wonders for the Park City side. As discussed in my book, under easterly flow there is a temporary shift in the windward side of the Wasatch from the Wasatch Front to the Wasatch Back.

Easterlies didn't prevail all last night, but they seem to have helped the last couple of hours.
