current conditions

The Tony Grove Snotel at 8400' reports 45°F this morning and 16" of total snow containing 116% of average SWE (Snow Water Equivalent). Temperatures again stayed well above freezing overnight across the zone, with 32°F this morning at 9700' CSI Logan Peak and 49°F at UDOT Hwy 89 Logan Summit. Record warmth of the past couple days melted a good deal of snow. Clouds, wind, and cooling temperatures will slow the melt today. A splitting storm system is already causing temperatures to drop, and mountain rain should switch over to mostly snow this afternoon. A couple inches of accumulation is possible.

Shallow, early season snow conditions exist, and hitting rocks or stumps is 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 ready to dig.

type aspect/elevation characteristics
over the next 24 hours

With only a couple inches of snow forecast in the mountains, the avalanche danger won't change much. Shallow wind slabs may develop on some upper elevation slopes by evening, but these should be easy to identify and avoid. The remaining November snow on most slopes is stable, and avalanches are unlikely. Even so, a ride in even a small avalanche could be particularly dangerous due to potential for being raked through rocks or deadfall below.


A Pacific storm system will cross Utah this afternoon through this evening. High pressure aloft will develop on Tuesday, followed by a fast moving weather disturbance crossing northern Utah Wednesday. Rain showers this morning will change over to mostly snow this afternoon, and 1 to 3 inches are possible. Expect a high temperature around 41°F​, and windy conditions in the mountains, with southwest winds 20 to 25 mph becoming northwest in the afternoon. Snow showers may continue in the evening with mostly cloudy conditions, then gradually clearing overnight. Low temperatures around 19°F are expected, with northwest winds in the 15 to 20 mph range decreasing to 8 to 13 mph by morning.​​ Tomorrow will be sunny, with high temperatures at 8500' near 36°F​ and north winds becoming light and variable in the afternoon.

A fast moving system will race across northern Utah on Wednesday, and along with wind and cooler temperatures, there's a chance for an inch or so of accumulation. In the long term, there is still some disagreement among the models, but hope is growing for a significant pattern change about a week out. There is good potential for "one of the colder storms the area has seen in weeks."
