FORECAST:

Ground hog day with a weak weather system similar to yesterday, but with a bit colder airmass and some light precipitation. Northwest flow aloft will continue today with the high building off the coast. A stronger weather system for Wednesday and Thursday will bring some much needed snow, the FL in the next few days hovers in the 1400 meter range with a spike to 1800 meters on Wednesday, dropping back to surface by Thursday night. Friday is looking unsettled as the high pressure begins to push into our zone. Long term we can expect the warm high to bring sun and warmer temperatures.
Guesstimates: 4-8 cm by Wednesday morning, 10-15 cm by Thursday morning, 10-15 by Friday morning.

Pretty big slide from the North bowls of Sky Pilot running down the gully that the summer route takes - maybe Saturday? Nick at left for scale. Edited a bit for contrast because of bad vis.
