2 AR's Phasing Together With Plenty Of Moisture And Cold Air.20 hours ago Powderchaser Steve
A very moist AR located off the coast of BC brings heavy snowfall to the PNW on Sunday into Monday. An arctic cold front drives in on the backside of this low crashing snow level to 500 feet with low-density powder continuing to stack up. Another AR off the CA coast merges with the northern branch to bring wet conditions to the Rockies. 12-20 Rockies, 1-3 feet PNW.

Deep Pattern Ahead for the Northwest2 days ago Alan Smith
The Northwest may be looking at its best pattern of the season as a series of strong and cold storms are set to arrive. The first storm will arrive over the weekend with heavy snow for the Cascades, Western Canada, and Northern U.S. Rockies. Snow will spread southward early next week with Utah and Colorado scoring the goods, and the Sierra will get in on the action as well.
