Recent Observations:
A handful of local shredders have been getting after it this week, with no reports of snow behaving badly. We had one user submitted photo of a small storm slab near treeline on the west face of Gray Butte. Other than that, the two feet of recent storm snow has been settling nicely. As a cohort of mine said, "Never underestimate the ability of a massive dump to do absolutely... nothing." What is possible during big storms can go either way: a big avalanche, or none at all. So it goes. Avalanche center staff has been poking our noses in many zones around the forecast area and have not observed any lingering weak layers or signs of danger. The past two days, warmer temps and the good old California sun gave the new snow a solid bake. Temperatures over the past 24 hours have averaged 28° degrees, with a max of 39° and low of 15° near treeline on Mount Shasta. Wind has blown predominantly out of the northwest, averaging 16 mi/hr with gusts to 49 mi/hr. Last night, a dusting of new snow fell. Snow surfaces will get a more robust refresh this weekend, but for today, expect Shasta variable...the post storm, sun baked, wind affected, crust, powder smorgasbord.
Mountain Weather:
Rain and additional heavy mountain snow will return to the West Coast on Saturday. A storm system tracking southward across the Pacific Northwest and California on Saturday will produce moderate to heavy precipitation across coastal portions of the region, with heavy snow possible in the higher terrains of the Sierra Nevada and Cascade ranges. An additional several feet of snow will be possible in these areas. A winter storm warning remains in effect from 4am Saturday to 4pm PST Sunday. The main event arrives at our doorstep tonight and continues into the weekend, bringing another round of significant winter weather impacts. Snow levels will be as low as 500 feet on Saturday morning. This event is similar from the one we just went through. Longer term, there are signs of a major pattern shift toward milder weather in the latter half of next week as the low lifts out and ridging develops.
