A weak cold front in a Northwesterly flow aloft will reach the coast later this afternoon. Overcast conditions for today with very light snowfall starting later in the day. The freezing level will likely reach 1400 meters by noon with daytime heating. A deep upper low out of the Northwest will push a trough through on Wednesday into Thursday. The FL will remain in the 1500 meter range for Wednesday and drop to almost surface as the trough out of the Bering Sea with its colder airmass gets closer on Thursday into Friday. Depending on the track we could get a significant amount of snow for Thursday into Friday. (20-40 cm possible over the 2 days). More on that as we get closer.
Guesstimates: 2-4 cm by Wednesday morning, 5-10 cm by Thursday morning, 15-25 cm by Friday morning, 10-15 cm by Saturday morning.

Superb conditions on Spearhead yesterday--it doesn't get any better! Moderate avi conditions, deep winter pack, fast and fluffy snow, (mostly) clear sunny skies, but air temps stayed cool. Thus my decision to go all the way around after touring to Trorey--Decker col with friends. I only passed 3 parties on the 35km--felt remote like 20 years ago--incredible! Overlord rock step is a non-issue (can side-slip down on soft snow, just a couple of metres). Step down to Naden Glacier easy boot pack (axe is handy) and Ripsaw crevasse well filled in. Singing Pass trail in awesome fast shape--some big roller coaster moguls but everything well filled in, including all bridge crossings. Made decent time (7:55 hours), Blackcomb Glacier to Whistler Village. I counted 18 unavoidable transitions, so that really cuts into travel time...So grateful for being able to experience this amazing, majestic landscape!
