  .SYNOPSIS... 
  Temperatures will remain below normal for this time of year today.  
  Significant warming will take place Monday. Widespread triple  
  digit heat is expected in the San Joaquin Valley Tuesday and  
  Wednesday, prior to a cool down late next week into next weekend.  
  Dry weather will persist.

  .DISCUSSION... 
  Omega blocking pattern locked in place across the lower 48 at the 
  moment. This will break down today as the upper trough over the 
  PACNW will open up and move east which will allow the ridge to 
  settle south. We will see two more days of below normal 
  temperatures before a gradual warm up will take place across the 
  CENCAL interior.  
   
  Guidance is advertising temperatures to reach near normal by 
  tuesday and slightly above on Wednesday. We are expecting another 
  trough of low pressure to move into the PACNW by Thursday night. 
  Synoptic scale cooling is expected by Friday and continue into 
  Saturday with a decent marine push on Thursday for the SJV. Best  
  dynamics will remain well to the north and we are not anticipating 
  any precipitation across the Sierra with this trough. So another 
  decent late summer cooldown across the region is in store after a 
  brief warmup.
