The surface snow was super saturated yesterday and temperatures stayed well above freezing overnight, with 40°F readings this morning at the Tony Grove Snotel and UDOT Hwy 89 summit. Daytime high temperatures are forecast to push 50°F today and again on Thanksgiving Day, and surface snow conditions are likely to remain soft, saturated, and prone to wet avalanches. A ride in even a small avalanche could be particularly dangerous due to potential for being raked through rocks or deadfall below. As soon as we get a good freeze, the snow will crust over and the danger will diminish.
The Tony Grove Snotel at 8400' reports 40°F this morning and 22" of total snow containing 152% of average SWE (Snow Water Equivalent). Rain Monday night and warm temperatures saturated the surface snow and turned the nice powder from the weekend into slush. Snow coverage is good for this time of year in the central and northern parts of the zone, and the wet snow should set up solidly when temperatures cool down.
Shallow, early season snow conditions exist, and hitting rocks or down and dead wood presents a significant hazard. Travel cautiously and keep your speed down. The Tony Grove Road is not maintained for wheeled travel in the winter, so if you venture up, have all the needed gear, be patient and be ready to dig.
Good coverage in the Central Bear River Range, but rain and warmth destroyed all the nice powder.
Evidence of a small wind slab avalanche was visible on Sunday in East Miller Bowl south of Tony Grove Lake. I think this was a natural from during Friday's storm, but there were some ski and board tracks nearby.

High pressure will continue to strengthen across the region today, then remain in place through the rest of the week. We should see some sun in the mountains today, with a high temperature at 8500' around 46°F and 15 mph south wind, veering from the west during the day. Expect partly cloudy skies overnight with low temperatures around 36°F and moderate winds from the southeast. It'll be mostly sunny on Thanksgiving Day with a southerly breeze and a high temperature around 49°F !
