In the words of Oliver Twist, “Please, sir, I want some more!”
Last night kicked off our return to a pattern that is producing the classic Utah snow we know and love. A cold front pushed through the region producing nicely upright snow, with cold northwest flow behind the front topping us off with some total blower powder. Park City/Deer Valley topped out with ~16″ and LCC/BCC resorts were not far behind with ~12″ overnight. Northern resorts saw a little less, with Pow Mow taking the cake at ~10″.
As the cold front remains stalled in the region, a weak disturbance in southern Idaho will drive the next batch of snow to fall. With modest upper level dynamical support and 700 mb temperatures nearing ideal for dendritic growth, by the time resorts open in the morning, we should see totals of 5-10″ in most locations, with 3-6″ in the northern Wasatch.
Precipitation will become steady and remain so throughout the day Thursday, interspersed with periods of heavy snowfall. Most of this snow will fall as 20-25:1 and should ski great on top of what’s already down on the ground. The NAM 12-km calls for about 10″ during the day tomorrow, which provides a decent baseline for our range. With a west/northwest flow at mid-levels, orographics will likely contribute handsomely to the totals in the upper Cottonwoods. Expect 8-16″ for LCC/BCC resorts, and 6-10″ for Park City area resorts by sunset. Models have the Northern resorts splitting the difference, with 8-12″ likely.
Snow will continue overnight into Friday, with models shutting the tap off mid-morning. Ample moisture remains, however. We’ll follow up on how this looks with tomorrow’s forecast. Enjoy!
