How about Some Cold, Moist, Northwest Flow?

Last night's storm delivered nicely across the central Wasatch with most upper-elevation sites reporting a foot or more.

Although we're in a bit of a lull at present, the pattern setting up through Friday generally looks like a good one.  Today is a bit tricky, with the front sort of pinwheeling around and going through various phases of redevelopment, so I'm not sure how it's going to play out, but after that, we're in cold, moist, northwest flow for the rest of the workweek, such as advertised below by the NAM for 5 PM tomorrow (Thursday) afternoon.

A quick look at the NCAR ensemble shows today's lull, but then the likelihood of precipitation increasing in the afternoon.  The waxing and waning of snowfall in the cold, unstable post-frontal environment is very difficult to time, but overall, I would expect we will see periods of snow showers through Friday (the graph below covers only through tomorrow afternoon, but other models support that view).

Much of that snow will be of the low-density, cold-smoke variety in areas where it is not hammered by the wind.
