  .SYNOPSIS... 
  Dry conditions and a cooling trend are in store during the  
  weekend along with some gusty winds. Temperatures through Thursday 
  will remain below their typical values for the first half of  
  September. Temperatures are then expected to warm up again later  
  next week with dry weather continuing.

  .DISCUSSION... 
  High pressure has been displaced from our region as shortwave 
  energy tracks inland across the west coast. The effects of 
  weakening high pressure began Friday with a slight downward trend 
  in temperatures, but still several degrees above climo. Another 
  incoming Pacific trough will bring further cooling to our area 
  today, lowering temperatures several degrees to slightly below 
  normal for the first week of September.  
   
  This cooldown today will be accompanied by increased gusty winds 
  as the trough pushes through the region. With gusts expected 
  around 35 mph in the San Joaquin Valley and around 45 mph through 
  and below Kern County mountain passes, Wind Advisories are in 
  effect for these areas this afternoon and tonight. 
   
  Temperatures will continue to lower several degrees in the dry  
  northwesterly flow behind the cold frontal trough, and Sunday  
  highs will top out around 8-12 degrees below normal. Models are 
  similar in maintaining the troughy pattern in place along the west 
  coast as reinforcing shortwave energy tracks through on Tuesday. 
  This pattern will maintain the well below normal temperatures 
  through the middle of next week.   
   
  By the end of next week, high pressure rebuilding north and 
  westward will bring an upward trend in temperatures, and highs are 
  expected to climb back to near seasonal averages. Dry weather 
  continues throughout the period.
