(Updated Sunday, Feb 12 for Monday Feb 13) - 16-24 Feb looking good from Squaw Valley to Kirkwood, Mammoth Mountain, also to Southern California's resorts including Mountain High and Bear Mountain, Snow Summit, Snow Valley (heavy snow at times during this period), and the Arizona Snowbowl. Snow will also hit the northern through southern Rocky Mountains, with snowfall more moderate (some heavy) there.
By the 16th - 18th (Thursday through Saturday), we see a strong and consolidated jet stream start pushing in across the west coast, and the rest of the western US by Sunday (19th) and into the following week (including southern California where some big storms are likely), with a renewal of snowpack building storms, colder this time around than with the last round of storm systems. This unsettled pattern should last through the 24th or so, followed by another high pressure ridge and mostly sunny conditions for Western US mountain resort areas.
