This morning, it's 39° F at the Tony Grove Snotel at 8400 feet, with 25 inches of total snow. Once again overnight, the station reported some precipitation, but no new snow. Winds are sustained from the west, gusting over 40 mph, but there is little drifting.
Last weekend, the wet, warm, and windy storm produced nearly 3 inches of SWE (snow water equivalent) and about a foot of dense, heavy snow. The storm deposited a dense slab of heavy snow on top of a very weak, faceted snowpack from November. This strong-over-weak, poor snowpack structure was responsible for many sizable natural avalanches, as well as red flags—like whumfing and shooting cracks. Although these obvious signs of instability are now much less frequent, snowpit stability tests still indicate potential for slab avalanches to propagate across slopes.
Tuesday's snow stability tests in the Emigration Creek drainage showed potential for avalanches to propagate, and continued instability in some areas...Below is a video of snow stability tests from Emigration Creek area on December 9
NWS Forecast Discussion: High pressure will be in place through the weekend, with dry conditions and temperatures around 10-20° F warmer than normal. Valley inversions will build as high pressure is in place. Unsettled weather looks to make a return to northern Utah by the middle of next week.

A rider reported triggering an avalanche on a northeast-facing slope near 9000 feet on Sunday while riding near Doubletop Mountain in Steep Hollow. The slide broke on weak, old faceted snow that was buried during last weekend's storm. His full observation is HERE.
