Monday afternoon update:
Snow continues for the valleys and benches of the Wasatch Front. As you head up to the Wasatch crest and east onto the Wasatch Back, the snowfall declines drastically. Our issue right now is that we have a weak flow, which is having trouble pushing the moisture up into the mountains. The other issue is that the orientation of the flow has been more north to south, without much westerly component. The westerly component is critical to get moisture to get orographically enhanced as it encounters the steep terrain of the Wasatch.
Therefore, snow is stuck in the valleys west of the crest, and man is there a lot of it! Some areas of the benches approaching 2 feet! This morning, I highlighted that if the orographics didn’t produce, we’d likely stay under 2 feet in the Cottonwoods. It looks like that will be the case right now — although that is certainly far from guaranteed. Still, there was at least a foot of snow when I was in LCC this morning. And more snow should continue tonight — so we are still going to be well within that 1-2 feet range in the Cottonwoods. Park City is reporting 5-8″, still expect a few more inches tonight up there. So they should at least make the low end of the forecasted 8-15″.
An interesting storm, that’s for sure! WSF
Snow will continue through the morning, then a break during the afternoon. Then orographics take over for tonight with additional accumulations likely through Tuesday morning. Generally active pattern looks to continue all the way until Christmas with storms likely every few days.
Snow has been falling over much of the Wasatch and Wasatch Front for several hours (as of 5:15am) in a pre-frontal southwest flow. This has favored areas such as Snowbasin which is reporting 12″ of snow already! Going to have to bump up their predicted totals!
Sundance, another resort favored by this flow saw snow develop later, but is doing well with 7″ so far and counting.
The Cottonwoods do not do great traditionally in a SW flow, but still, snow is falling there as well as PC and the flow should turn more westerly soon.
Outside my house in the Salt Lake Valley, it is absolutely nuking right now with several inches already on the ground. Getting up to the resorts this morning is going to be tricky.
Snow will continue for most of us through the morning hours. The front will pass to our south and east for the afternoon and the Wasatch and Wasatch front will be left in a dry slot. Do not panic if there is a break in the action this afternoon! It looks like the wrap around moisture and north-northwest flow will develop this evening and snow should fall tonight, especially in the Cottonwoods.
Snow will start to taper off on Tuesday, but not before we’ve seen some impressive accumulations.
Based on what we’ve already seen, I think 16-24″ is likely for snowbasin. 10-20″ for Powder Mountain/Beaver. 10-20″ for PC/Sundance. Based on the Cottonwoods favored location for orographics, if the orographic machine really starts cranking tonight, I think 24-30″ is possible. If the flow is too northerly, then perhaps 12-24″ is more likely. No matter how you slice it, this is a great storm.
The roads will likely close at times for avy control… FYI… be prepared.
Active weather looks like it will continue in the long-range, but I can’t get too into the details. I have powder to ski, y’all! See you on the hill.

Powder to the People! (finally) Jeez, I can barely see my neighbor’s house! Insane snow rates right now!
