The large scale pattern is illustrated nicely by the 12-hour GFS forecast valid at 1200 UTC (0600 MST) this morning (sorry to use a forecast, but I have a narrow window to write this). An upper-level ridge is parked off the U.S. West Coast with strong water vapor transport (color scale) extending inland into Utah.
Patterns like this are often called dirty ridges by meteorologists since clouds and precipitation extend well downstream of the ridge axis. Well oooh baby, talk dirty to me as I like the precipitation numbers coming in from the central Wasatch in these early storm stages.
From 3 to 8 am this morning, Alta-Collins has picked up 6 inches of snow with 0.53 inches of water. Our "Top Cecret" observing site in Albion Basin is at 4 inches with .39 inches of water. It's mild by climatological standards, but temperatures this morning are at or below freezing at the central Wasatch resorts, including those on the Park City side. Thus, we're getting some snow at mid elevations so far and we'll take all we can get.
