Wednesday Evening....

Main low with cold front is moving down the coast & should start to move inland over Washington. Snow showers are already starting with the moist flow off the ocean, & should be heaviest late tonight into Thursday morning as the cold front comes thru. Snowing currently at 6000 ft. so snow levels should be below lake level thru the event. Models back & forth on amounts of 3-6 or 6-12 inches. Let's just split it and go with 4-8 inches on the mountain by Thursday afternoon, up to a foot on the crest. There will be some shadowing since the front is weak.

No changes on the set-up for the weekend with a low setting up out in the Pacific tapping subtropical moisture while we are quiet Fri. & Sat. Storm heads NE towards Washington and bring moisture band into the Sierra by Sat. night. With the subtropical moisture snow levels should start around 7000 ft. but then fall as the colder air filters in under the main low off the coast on Sunday. GFS going more in line with the Euro in keeping the low over the ocean with the subsequent storms diving underneath it and tapping some more subtropical moisture, thus keeping the snow wetter, but snow levels should be at or below lake level by Sunday morning. This storm should drop at least a couple feet on the Mountains.

Snow showers last into Tuesday before another storm taps some subtropical moisture and slams the Sierra with more snow measured in feet. Yet another storm still looks possible for Thursday with more storminess possible for the following weekend. Next week looks to quite stormy and the mountain could get quite a bit of snow with a fair share in town. Will have to iron out the details in the next few days but the pattern is perfect for lots of snow.

Latest long-range models continue to keep the ridge planted in the Central Pacific. March will come in like a lion, and hopefully go out like one too. BA

Thanks BA, is Kirkwood going to get any rain as well?

Doubt it, they are too high. I would think by they time all the resorts open on Sunday they will all have snow top to bottom.
