Snowpack Summary
Forecast new snow, wind, and cooler temperatures will bring back winter to higher elevations for a day or two. Expect the old surface to re-freeze overnight and some new wind slabs may form in the lee of southwest winds. These new wind slabs may not bond well to the old hard surface. Surface crusts may break down rapidly if the sun comes out, especially on steep slopes with direct sun exposure.
