As of 5am, snowfall totals are 2-3" on the storm boards in the upper Cottonwoods, and with a snow-water-equivalent of 0.41", it's little surprise that it's
graupel bring reported. The Park City ridgeline has a trace to two with the Ogden and Provo mountains about half that. With the passing of the wave, winds are continuing to veer (moving clockwise from southwest to west) this morning and are blowing 15-20mph. Temperatures are in the mid to upper 20s and dropping. Total snow depths are 3-4' in the upper Cottonwoods and 2-3' along the PC ridgeline.
For today we'll have off and on snowfall with light snow falling down to the benches. 5-10" possible in the mountains by tomorrow. Winds will be 10-15mph from the west/northwest. Temperatures will be falling to the low 20s.
A shortwave ridge builds in for Monday night through early Wednesday with a quick cold front slated for later Wednesday. Additional storms arrive on a westerly flow follows for Thursday through the weekend.

Week in Review for a summary of the weather and avalanche activity from the past week.
Ski area control teams continue to trigger large and impressive avalanches into the old snow near the ground. Yesterday, in mid-Little Cottonwood, a single explosive pulled out a very large avalanche 3-4' deep and a couple hundred feet wide on a steep northwest facing slope at roughly 10,700'. Parts of the slab had old black holes from previous work with the howitzer. This well mirrors the inconsistent yet eye-opening situation in the backcountry: land mines continue to be found every day, keeping us all on our toes, taking nothing for granted.
In upper Big Cottonwood Canyon yesterday, two people were caught and carried in the Hidden Canyon area along the Brighton periphery. This was on a northwest facing slope at 8800', 2' deep and 100' wide. Little more is known - and thanks to the reporting party; I'll try to follow up more with them today. (pc: Mace)
Across the range, however, some steep lines continue to be ridden in suspect terrain with no incident. These we call "non-event" feedback and I would caution people to build confidence based upon what we know of our snow structure.
In the Bear River Range just north of the border into Idaho, two snowmobilers were caught and carried with one partial burial in an avalanche but ended up ok.
