Take this with a small grain.... The new ~5cm (2") we received in the past 24 hours will give us a +normal caution avalanche problem today. The strong overnight winds have broadcast & pulverized the new snow into small wind slabs on the North through East aspects. One very small R1D1, Soft Slab, avalanche was observed at treeline on an east aspect. These instabilities are small & isolated to the NE aspects & will include the new snow that may have built up to 13cm in terrain features.
~5cm of new snow fell in the last 24 hours & was blown around by the SW winds. The precipitation sits atop an unsupportable crust that developed within our most recent dry period. Near-surface faceting had occurred just below this crust & is the primary layer of concern. Stability tests were showing failures, which did not propagate, 15cm deep at the bottom of this crust. A small dose of rime & graupel was observed early on in the frontal passage, with no visible accumulations. Our snowpack is still very thin!

A more seasonable cold air mass has settled into the Eastern Sierra region. Around 5cm (2") of cold-smoke fell in the past 24 hours with strong winds. Patchy clouds & continued winds will be seen today & tomorrow. Any precipitation that can squeeze out of the clouds will be in trace amounts. A warming trend will continue throughout the weekend & another cold front sweeps through early next week.
