This morning, it's 25° F at the Tony Grove Snotel at 8400 feet, with 26 inches of snow that's continuing to settle after this weekend's storm. Overnight, moderate winds were sustained, shifting from the northwest to southwest while gusting into the mid-50s mph. Overnight mountain lows hit 21°F on Paris Peak, and highs reached 36°F on Logan Summit.
Over the weekend, the wet, warm, and windy storm 12/5-12/6 dropped 2.8 inches of water and about a foot of dense, heavy snow on top of an already weak, faceted snowpack from this fall. This strong over weak snowpack structure is responsible for many natural avalanches that were large enough to bury a person, as well as too many other red flags—like whumfing and shooting cracks—to count since Friday.
Today through tomorrow, wind and rain are mostly on the menu for the Logan zone. An atmospheric river makes its way over the PNW through to Montana and Northern Idaho. A building ridge over the eastern Pacific pushes this moisture mostly north of us, but there's a potential for up to a half inch of water to spin into the Bear River Range this morning through tomorrow evening. Unfortunately, our warming trend continues. Precipitation will mostly fall as rain as snow lines rise from 7000 feet to almost 9000 feet by tomorrow. If we see the higher end of these totals, we may start to see wet snow issues.
Looking ahead, things look dry and warm. Temperatures will push into 10-15°F higher than normal Thursday into the weekend.

A rider reported triggering a 2 foot deep avalanche, depositing 6 feet deep debris, on a NE-facing slope near 9000 feet on Sunday while riding near Doubletop Mountain. The slide broke on weak, old faceted snow that was buried during this weekend's storm. His full observation is HERE.
