Weak, sugary, or faceted snow from early November is widespread in upper-elevation terrain. Today, people could trigger avalanches in the backcountry. Yesterday's snowfall probably overloaded some slopes with poor snow structure, causing elevated avalanche danger on upper-elevation slopes steeper than 30°. In exposed terrain, drifting built stiffer wind slabs on the underlying weak snow, and wind slab avalanches are possible. Although there may not be enough snow on many slopes to bury you, a ride over rocks in even a small avalanche could be quite dangerous.
- The 8500' Tony Grove Snotel reports 21°F and 8 inches of new snow from yesterday's storm, with 24 inches of total snow on the ground. It's 17°F at the 8800' UAC Card Canyon weather station, with 4 inches of new snow and 25" of total snow.
- Currently at 9700' at the CSI Logan Peak weather station, it's 14°F and the wind is blowing from the northwest 17 mph, with overnight gusts generally less than 30 mph. At 9500' on UAC Paris Peak it's 12°F, and winds are from the north 5 mph.
- Today, snow will taper off early this morning and the sun will come out. 8500' high temperatures will be around 21°F and winds will blow from the northwest around 7 mph.
Tonight, temperatures will drop to around 13°F, and winds from the west-northwest will blow 5 mph.
Thanksgiving Day, it will be sunny. Expect high temperatures around 19°F and light winds from the west 5 mph.

A high-pressure system will gradually build over the area, and we can expect stable atmospheric conditions, fair weather in the mountains and haze in the valleys for at least the nest week.
On Sunday, observers reported triggering a few audible collapses or "whumpfs" in north-facing terrain at around 8700' in elevation. These triggered collapses are a red flag indicating unstable snow.
No significant avalanches have been reported yet in the Logan Zone.
