  .SYNOPSIS... 
  A warming trend will continue for the next couple of days, with  
  temperatures well above seasonable normals. A weather system will 
  bring cooler temperatures for the latter half of the week, along  
  with a chance for precipitation Thursday into the weekend.

  .DISCUSSION... 
  Warm and dry trend continues today as the region observes above  
  seasonal normal temperatures. While some high clouds will be  
  observed today from a storm pushing through the Pacific Northwest, 
  these clouds will do little to slow down todays warming. The  
  ridge responsible for the current warming trend will hold over the 
  region through at least the middle of the week. During that time, 
  temperatures cloud reach about 10 to 15 degrees above seasonal  
  normal values. Yet, change is on the way as a storm system drops  
  from the Gulf of Alaska later this week. 
   
  A change in the weather will be ushered into the region starting  
  near the Thursday morning period and continuing into Friday.  
  Ensembles analysis in both the realm of predictability and  
  clusters show very high confidence in the transition to unsettled  
  conditions near the Thursday time frame. In the short term,  
  satellite water vapor and upper-air analysis show the progression  
  of an Atmospheric River (AR) as it travels through the Pacific  
  Northwest. While moisture from this AR will shift south toward the 
  Central California area later in the week, the magnitude of its  
  moisture will be much less then that needed for a full AR.  
  Therefore, with no continued feed from the subtropics by Thursday, 
  will see just enough moisture entering the region for light to  
  moderate precipitation rates. Current projections of precipitation 
  accumulation show the valley receiving between a quarter to a  
  half inch through Friday afternoon. The foothills and Sierra  
  Nevada could receive up to an inch of water equivalent liquid due  
  to orographic enhancement for the same time frame.  
   
  Ensembles (and cluster analysis) suggest a return to colder  
  temperatures toward the end of the week and int the weekend.  
  However, upper-air ensemble analysis is not projecting to return  
  of below freezing temperatures. Due to the trajectory of the next  
  storm, Central California may not be favor for a full AR event,  
  yet, confidence in higher for probability of measurable  
  precipitation.  
   
  Any precipitation will be good news. Hopefully, ensemble  
  continues in the direction of precipitation for Central  
  California. Ensemble do not hint toward the return of the West  
  Coast Ridge until closer to the day seven period. Therefore,  
  hopefully the period of unsettled weather may be extended into the 
  weekend for even more precipitation during the latter parts of  
  the forecast period. Again, any additional would be a benefit to  
  the region.

  .AVIATION... 
  VFR conditions will prevail throughout the Central CA Interior  
  for the next 24 hours. 
   
  && 
   
  .AIR QUALITY ISSUES... 
  None.
