Recent Observations:
Yesterday's observations were lackluster in the unstable snow department. It was one of those freezing fog, misty, poor visibility days...the kind that ruins your goggles in about 30 seconds flat if skiing or riding. The short, punchy storm that rolled through overnight on December 28-29 brought 8–10 inches above 7,000 feet. Precipitation ended at 1000 hours and kicked back in at 1700. Temperatures started off cool, but have been warming. Westerly wind was calm midday, but turned on last night. Storm snow stability is good below and near treeline. I was unable to get into colder, windier, upper elevation terrain due to whiteout conditions.
- December 26/27 storm, 8–14 inches above 7,000 feet of dense snow that is well pasted to existing snow surfaces
- December 29th storm, 8–10 inches above 7,000 feet of soft snow resting on top of heavy, dense snow
- Potential weak layers of snow will reside in new storm snow and/or new/old snow interface since December 29th.
- In the last 24 hours:
- Temps (low/high): 19/24 deg F
- Wind (avg/max): 11/37 mi/hr - West
- Precip (SWE): 1.08" snow-water equivalent
- Height of Snow - Mt. Shasta: 72" / Castle Lake: snow depth sensor down, estimated 50" / Mt. Eddy: 48" inches / Ash Creek Butte: 58"
Mountain Weather:
We are riding the second wave of the storm train, and it's a warm one. Rain, snow and strong westerly wind over higher terrain will prevail for daylight hours today, tapering off late this evening and into Saturday morning. Snow levels are once again painfully high: 8,000 feet today, lowering to 6,500 feet tonight and 4,500 feet tomorrow. Cooling off, yes, but too little, too late with this storm. Snow is likely above treeline on Mt. Shasta. Near and below treeline, a winter mix of rain and snow. Precipitation will end from northwest to southeast Saturday afternoon. A short-lived break in the action will follow on Sunday. A colder front with lower snow levels moves onshore Monday, and the associated energy will be focused on northern California.
