Recent snow and a good weather forecast should produce some great skiing this week. The main concern is for freshly loaded steep and shallow terrain in the alpine, where facets may exist above a widespread crust (Nov11) found in the midpack.

Summary

Snowfall to taper off by Sunday morning, with only light intermittent flurries and a cloudy day. Winds light from the Southwest. Temperatures falling to -12C by Monday morning, along with a clearing trend.
