The storm from Wednesday night and Thursday ended up putting down about 5 inches of cold smoke on the Alta-Collins stake. Then, last night, we got another 8 inches of cold smoke with only .21" of water, which yields a water content of only 2.6%. Given the measurement uncertainty, that number might be a bit higher, but we're still talking very dry snow.
The loop below shows very nicely the overnight trough passage and the accompanying transition in storm characteristics. Snowfall was widespread ahead of the trough, producing both valley and mountain snow, but with the trough passage, we've seen a transition to precipitation being confined to mainly near or over the Wasatch Mountains, including portions of the east bench.
