  builds in the Eastern Pacific.

  .DISCUSSION... 
  Current shortwave ridging over head will give way to an upper  
  disturbance coming from the northern California Coast this 
  afternoon. Afternoon high temperatures are forecast to be several 
  degrees below normal this afternoon as cloud cover increases ahead 
  of the incoming trough. Slight chance of light rain in the SJ 
  Valley starting mid morning today and shifting southward  
  throughout the afternoon. Light snow is possible in the Sierra  
  Nevada mainly north of Camp Nelson beginning around noon today  
  lasting through the night, with very light accumulations (1-2  
  inches) above 5000 feet. Rainfall totals in the San Joaquin Valley 
  will be nominal, with only a few hundredths of an inch expected.  
  A second disturbance will impact Central California Sunday.  
  Associated with the second ULL is another round of light precip,  
  cool afternoon highs, and light snow in the Sierra Nevada through  
  the afternoon. Snow levels will be in the 4500-5000 foot range  
  Sunday, and snowfall totals in the Sierra Nevada again in the 1-2  
  inch range. In Kern County there will be some gusty winds through 
  and below the Kern County Mountain passes Sunday afternoon and  
  evening as gradients increase.  
   
  Pattern change will begin early next week as a ridge of high  
  pressure builds in the Eastern Pacific. This will place much of  
  California in dry, northwesterly flow through the rest of the  
  forecast period. Monday and onwards we will be in a drier and  
  warmer airmass, with afternoon highs Monday starting in the upper 
  60s to near 70 degrees and trending upwards through the work  
  week with highs near 80 by Thursday. Longer range models indicate 
  that the dry and warmer pattern will persist into next weekend.
