Recent Observations:
Over the past 24 hours, the mountains of southern Siskiyou County have received 2–4 inches of new snow. Southwest wind has been predominant, averaging 11 mi/hr with gusts to 43 mi/hr. Temperatures have averaged 23 degrees. Yesterday on Green Butte Ridge, it was a chilly day with poor visibility above treeline, light snow and moderate, gusty SE-S-SW wind. New snow distribution was uneven, with southerly wind blowing snow onto westerly and northerly aspects. Along Green Butte Ridge, the W-NW side of the ridge had better coverage than the windward SE-E side. Small wind slabs up to one foot thick could be found around tree wells and other leeward terrain features. Conditions were a level above dust on crust…we'll call it fluff on crust. Wind exposed areas were scoured down to the old, icy surface. Crazy amounts of tree debris litter the snowpack. It will take a foot or more of new snow to bury the detritus completely. Until then, watch out for sharp wooden objects. On the down, ski edges found chunky, icy surfaces below the fresh snow.
Mountain Weather:
A front in the eastern Pacific will move over the west coast today and tonight, tracking southeastward. Today, the system will produce coastal rain and higher-elevation snow over northern California and the Pacific Northwest. Showers have dissipated overnight, but the dry weather won't last long; the next system is close behind. Expect another period of breezy winds ahead of the storm. Precipitation will be more widespread and with greater amounts than the previous storm. Showery conditions will linger Sunday. Snow levels are fairly high with this event due to southerly flow bringing in warmer air to the region...they will hover around 5,000 feet this afternoon/evening, lowering to 3,500 feet as colder air moves in tonight.
