  A disturbance will bring mountain snow today and tomorrow for the  
  northern portion of the Southern Sierra Nevada. A second 
  disturbance will usher in cooler air, light precip, and gusty 
  desert winds Saturday night through Sunday. Ridging Monday and 
  Tuesday will keep weather quiet before another possible storm 
  system impacts Central California mid week next week.  
  Latest Goes 17 satellite nighttime imagery reveals patchy areas  
  of dense fog in the western portion of the San Joaquin Valley  
  early this morning as the ridge of high pressure that has been  
  over us the last few days begins to shift south. CHP reports of  
  car accidents and local web cams reveal low visibility in fog, so  
  have issued a Dense Fog Advisory until 10 AM for the western  
  portion of the San Joaquin Valley. Upper level model progs show a  
  disturbance beginning to impact Yosemite NP by 10 AM this morning. 
  This disturbance will bring high elevation snow to the Sierra  
  Nevada today and tomorrow, with snowfall totals of 4-8 inches of  
  snow possible above 7000 feet through 10 AM Saturday morning, with 
  local amounts of 10-12 inches possible along the crests. A Winter 
  Weather Advisory remains in effect through 10 AM Saturday for the 
  Southern Sierra Nevada above 7000 feet for Florence Lake and  
  northward. In the SJ Valley, precipitation is expected to spread  
  southward Friday night into Saturday morning, but accumulations  
  look to be very light, with QPF totals only around 0.1".  
  Another disturbance will move inland bringing cooler air, light 
  precip, and gusty winds through and below the Kern County Mountain 
  Passes. Snow levels will fall to 3500-4000 feet by Sunday, but  
  this system will but cut-off from a rich moisture source, so QPF  
  totals will be scant. The winds in the Kern Co Desert will  
  probably be near or at Advisory level by Saturday  
  afternoon/evening, which may make travel difficult for high  
  profile vehicles.  
  Monday and Tuesday look to have calm weather as models build a 
  ridge of a high pressure aloft above Central California. Another 
  disturbance looks to be aimed at us by mid week next week,  
  however, there is significant disagreement on the timing of the  
  next trough. The EC ensemble is slower and farther south than the 
  GEFS with this system, so the impacts of this trough are  
  uncertain as of this writing. Details will be ironed out in the  
  coming days.
