  .SYNOPSIS... 
  Slight chance of precip in the Sierra Nevada today and tomorrow as 
  a disturbance passes to our north. Dry weather through the rest of 
  the work week as a ridge of high pressure builds, which will also 
  be conducive to morning fog in the valley. Next chance of precip  
  may occur later this weekend.

  .DISCUSSION... 
  Latest GOES 17 satellite IR imagery reveals high clouds 
  progressing over the district early this morning. Currently 
  expecting morning lows to be around 39-42 degrees across most of 
  the San Joaquin Valley. Some mixing may occur this morning ahead 
  of the disturbance to our north, potentially preventing  
  widespread fog across the Valley. Precipitation is possible in the 
  Sierra Nevada this afternoon through tomorrow afternoon for  
  Fresno County and northward, but model guidance is showing QPF  
  totals to be scant as the main precip will be further north,  
  associated with the upper low. Gradients in Kern County may  
  tighten up by Tuesday afternoon through Wednesday morning to  
  generate gusty winds in the Kern County mountain passes and Mojave 
  Desert.  
   
  Wednesday, models are in agreement that a ridge of high pressure 
  will begin to build over Central California. This will lead to a 
  period of dry weather with morning bouts of fog likely across the 
  Central Valley. Upper ridge will begin to weaken by the end of the 
  work week as an upper trough approaches the west coast. Blended 
  model guidance is showing a chance of precip for the forecast area 
  by Sunday as the trough nears, however the location and timing of 
  the trough this far out is somewhat unclear. Either way, it will 
  likely break up the stagnant weather pattern that is forecast to 
  occur for the latter portion of this work week. Details regarding 
  this system will be ironed out with additional model guidance.
