Calm Before the Storm.......

Northstar picked up 3" overnight, which puts them exactly 6 feet off of their seasonal average. We have a chance at hitting that in the next week! Areas along the crest about 5-9 inches. Snow showers could persist off and on thru the day but no more than a few more inches should accumulate.

Friday & Saturday look to be precip free as a low sitting off the coast strengthens & gathers moisture. On Saturday the low heads NE towards Washington & merges with a storm coming down from Alaska, thus merging the subtropical & the polar jet streams & creating a cold trough off the coast. This is a good set-up for us.

Subtropical moisture ahead of the trough looks to arrive sometime Sat. night into Sunday morning. At first snow levels will be around 7000 ft., but as the colder trough moves closer on Sunday the snow levels should drop to lake level. The heaviest precip looks to fall Sunday night as the jet stream sets up right over Tahoe. Above 7000 ft. 2-3 feet look possible by Monday with up to a foot at lake level & in town.

Snow showers should continue Monday into Tuesday before another storm wrapping around the main low off the Pac NW coast taps some subtropical moisture and slams the Sierra with more snow Tuesday night. Yet another storm still looks possible for Thursday as a final piece of energy comes down the coast. Tues - Fri. we could easily double what falls Sunday/Monday.

First weekend of March could be amazing after all the snow falls next week. We may get a break for a few days as the trough over the East I have been alluding to slows the progression of storms. That wouldn't last long as the latest long-range models continue to keep the ridge planted in the Central Pacific. Hopefully March is our biggest month this season. BA
