Recent Observations:
A bombproof snowpack exists throughout the forecast area. If my life depended on finding red flags of avalanche danger, I'd be dead. Generally smooth and slick surfaces will host new snow in the coming days. Yesterday, a few high clouds began to filter in, but overall it was mostly clear. A large lenticular cloud hung over the mountain for the majority of the day. Wind was light to moderate down near treeline, but the lens clouds indicated different conditions on the upper mountain. Snow surfaces are ragged below and near treeline. Tree debris is littered all over the snow pack. It's quite the spectacle and will take a foot or more of new snow to cover up the branches and limbs. Some softening occurred on sunny slopes, though it was very firm and icy in the AM hours. In the past 24 hours, no new snow has fallen. Light snow has commenced early this morning at 0600 hours. Current snow depth at treeline on Mount Shasta is 124 inches. Temperatures have ranged from 20° to 35° F. The wind picked up late last night and has blown predominantly out of the south and southeast, averaging 10 mi/hr with gusts to 42 mi/hr.
Photos taken on 2/2/23 on Mount Shasta, below and near treeline. A lenticular hung on the upper mountain for most of the day. / Meyers
Mountain Weather:
Upper-level energy will push onshore today. This marks the beginning of a progressive pattern, with systems passing through every two days or so. None of these systems are expected to be strong. Precipitation is moving inland this morning. Snow levels will hover around 3,500 to 4,000 feet. South/southwest flow will bring the heaviest precipitation to the Marble Mountains as well as the Mount Shasta area due to enhanced up slope, terrain induced precipitation. Minor issues on roads and highways are likely, with 3–5 inches forecast for Snowman's Summit. In general, 1–2 inches is likely for most roadways. Up on the mountain, expect a few inches more and gusty, south wind. A short break will ensue Friday afternoon. On Saturday morning, we'll start out with upper ridging over the area, but that will quickly move east as a trough approaches. Saturday evening through Sunday evening, we could see a fairly decent dollop of snow above 6,500 feet.
