The First major Atmospheric River event this year is shaping for Southern CA and the Southern and Central Sierra, for Mid-week. A wide swath of rich Precipitable Water will stream into Southern and Central CA beginning Tuesday night and will increase in its intensity Wednesday into Thursday. this is part of an Omega Block over the Central pacific and the eastern portion with its cut off low spinning at 140west and some 1000 west of the central coast tonight. The Duration of the event along with its intensity suggest that orographically favored areas on the west side of the southern sierra could get up to 10 inches of water from this storm. Here in the Eastern Sierra, the west side will take the brunt of the storm as well. However, not before squeezing some 5 to 7 inches of water over the Mammoth Crest for a good 5+ feet of snow, rich in water content. Snowfall amounts in town will vary greatly where the Mammoth Slopes area above 8000 feet will get a lot of snow through the period ending Saturday while the lower elevations of town get a lot of rain at times. So at times it will rain and at times it will snow at 7500 to 8000 feet. The Nested Grid model shows the snow level lowering into town by Thursday morning….This is Faster than predicted this morning. We still have another 24 hours to follow its progress, as the storm is still developing…. By Thursday night, the AR should be south of the state while the colder portion of the pattern with its cold GOA low digs south into Northern CA. This will bring colder lighter snowfall to the high country, Friday and especially Friday night into Saturday.
