Sierra picked up another 13 inches on top the past 24 hours which brings the 2 day storm total to 38 inches. Heaviest snow of the week should fall during the day today.
By tonight we should have another 18-24 inches from mid-mountain up, and 12-18 inches at the base. Then we tack on another 8-12 tonight from mid-mountain up and 4-8 at the base, with 6-12 tomorrow and 3-6 at the base. That should bring additional totals over the next 36 hours of 3-4 feet mid-mountain up, and 1.5-3 feet at the base. That would bring 4 day storm totals at the summit to 6-7 feet.
Then it looks like we could have a bit of a break on Tuesday as the subtropical moisture feed is in Southern CA. We could still see some snow showers with the cold air in place and moisture not far away. Thanks to the separation of the subtropical feed to our South, on Wednesday a cold storm storm will move in dropping 1-2 feet. Snow levels will be well below lake level. That should cap off our 6 day storm cycle with snowfall totals on mountain of 4-9 feet base to summit.
Milder and drier weather as we clear out Thursday through Saturday. On Sunday a cold front and storm will push through. It is too early to talk specific snow totals, but right now models have it in the 1-3 foot range.
By the end of the month a ridge will try to form around 150-160w which is the perfect location going into winter to bring us a series of cold storms. We won't need a base anymore after this weekend, so bring on the powder dumps. BA
