We ski toured today on the northern aspects of Commonwealth Peak and found pretty decent skiing with up to 20cm of new snow in the higher elevation - lee locations. The snowpack carried to the bottom of the valley. We noticed quite a few large cornices lingering at ridgeline that deserve attention / avoidance, especially in times of great temperature swings which we can expect in the next few days.
Only signs of instability observed today where some super-thin wind slabs close to ridge line. Winds were relatively light from various directions – mainly north-westerly but also north-easterly in the later pm as colder arctic artic air moved in.
As we left the valley around 5PM it was -12C and there were about 10cm of new snow at valley bottom over the previous temperature crust. Driving back to Canmore the skies cleared so I don’t think there is a lot more snow to be expected from this “little” cold front.
