It's mighty cold in the mountains again this morning, and we'll see clouds thicken today ahead of the next Pacific Storm. You'll find excellent shallow powder conditions, good stability and Low danger on most slopes in the backcountry, but heightened avalanche conditions exist on drifted upper elevation slopes. Shallow human triggered avalanches involving wind drifted snow are possible.
Fine shallow powder riding conditions and mostly stable snow in the Logan Zone, but heightened avalanche conditions exist at upper elevations where light snow was drifted into stiff drifts.
The Tony Grove Snotel at 8400' reports 7º F and there's 39" of total snow containing 83% of average SWE. It's 2º F at the 9700' CSI Logan Peak weather station, and west-northwest winds are currently averaging about 26 mph, with gusts around 40 mph.
A short lived high pressure system will be over the zone today, but we'll see increasing warm air advection aloft bringing clouds and a chance of a little snowfall. Tomorrow a potent wave with a significant Canadian cold air source will dive from British Columbia to Utah, and we'll see significant snow accumulations and fairly strong winds in the Logan Zone. Some of the coldest air of the season will filter into the region in the wake of the storm system for Monday and especially Tuesday.
Expect increasing clouds and a chance of snow showers today, with a high temperature at 8500' near 19º F and 10 to 15 mph west wind, Wind chill values will be as low as -21º F. Snowfall begins tonight, with temperatures rising to around 20º F and increasing southwest winds, 13 to 18 mph. 1 to 3 inches of accumulation is forecast. It'll snow tomorrow, with 6 to 10 inches of accumulation possible, a high temperature around 21º F, and 25 to 35 mph west-southwest wind and gusts near 50 mph.
Noticed some natural avalanche activity due to wind drifted snow in upper Providence Canyon, likely from overnight 12/27/18.
