Current Negitive Tilt Trof is lifting out to the Northeast through the Pacific NW……WX Front Washing Out Over Mono County…..

Upper Trof axis is NW/SE over Northern Ca. The WX front itself is over Mono County and is weakening…its remains will drag east as the front looses upper support.
As of 9:00AM the snow plot has picked up close to 7 inches with a few more inches possible by 18z. (11:00am). With the orographic component, I guess it is possible that the crest may get close to 10 to 12 inches by the time it is over. As the front weakens. snowfall will diminish today. Most of the precip will be over by 12:00 noon.
Although a flat ridge builds in Thursday into Friday, westerly flow will continue into the central west coast the next week. The storm over the weekend looks like a moderate quick hitter. 500mb Iso heights are tightly packed….so it will be a windy one. At the moment….the QPF is not all that impressive. Best guess about a foot over the upper elevations….will fine tune later.
The Dweebs are beginning to notice that the actions of the models are showing more of the usual Spring characteristics. A deminishment of accuracy in the medium range is noticeable. This is typical for Spring as the effects of differential heating begins to take effect.
The weather in the longer range is not as conducive to precipitation for the Mammoth area as the past weeks. The upper jet will migrate more to the north, with Northern Calif and the Pacific Northwest quite wet again. In fact there is a hint of a tropical connection for the Northwest later next week……
