This is probably as good as it can get for building up the mountain snowpack. There's nothing better for base than a heavy, wet snowfall to stick to everything and add some water mass. SWE-rates at CLN are now over 0.2 inches per hour and precipitation rates should remain high for several hours.
Take a look also at some of the banding in the radar image above, especially over the Oquirrhs and SE corner of the lake. Evidence of slantwise convection? That's not my game, so perhaps someone can chime in with an analysis.
