Not a lot of good news over the next couple of days. Only a few cm's of new snow forecast and a cold front will cause temps to drop into the -20 range so we can look forward to continued weakening of the midpack. Watch for soft slabs.
Weather Forecast
Increasing cloud cover later Monday into Tuesday with some very light flurries in the forecast that will likely only total a few cm's. An arctic cold front will slip into the area on Tuesday dropping temps into the -20 range . Some gusty NE winds Monday night swapping to more W / NW on Tuesday.

Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
