  .SYNOPSIS...A cold front will bring showers into parts of 
  the central California interior today into tonight along  
  with gusty winds through and below the Kern county mountain  
  passes. Dry weather can be expected Monday through Friday 
  with areas of night and morning low clouds and fog in the  
  San Joaquin Valley. Temperatures will average close to 
  normal through Tuesday. Springlike afternoon temperatures 
  can be expected later in the week through next weekend.

  .DISCUSSION...A Winter morning without dense fog in the San  
  Joaquin Valley is a good one, and so is the case early this 
  morning, thanks to a cold front that is approaching from the 
  northwest. The cold front shows up pretty well on the latest 
  satellite imagery and is defined by a narrow band of showers 
  which is currently moving through the San Francisco Bay area.  
  Well in advance of this system, radar is currently showing a  
  speckling of light showers from Fresno county northward.  
   
  It`s been 10 days since a storm system brought wet weather  
  into the central California interior. Unfortunately this will  
  be the last system to do so for at least the next 6 to 10 days.  
  Nonetheless, the cold front that breezes through the CWA this  
  afternoon will be accompanied and followed by some showers,  
  mainly over the eastern half of the San Joaquin Valley as well  
  as the foothills and mountains. Precipitation amounts will be  
  rather light with this feature. How light? Trace amounts to 
  several hundredths on the west side and in the south valley  
  to about a quarter of an inch on the valley`s east side and 
  adjacent foothills from Fresno county northward. The higher 
  elevations of the Sierra can expect a tenth to a third of an 
  inch with local amounts of up to a half inch. Snow levels  
  will start out around 8,000 feet then lower to about 6,000  
  feet by this evening with accumulations of 2 to 5 inches in  
  the Sierra, mainly north of Kings Canyon.  
   
  The upper level trough associated with this system is shallow, 
  the dynamics are weak, and the upper boundary layers are not all 
  that cold this far south to support instability thunderstorms 
  this afternoon. In collaboration with neighboring WFO`s and SPC,  
  we`ve decided to pull thunderstorms out of the forecast for today. 
  In the wake of the surface cold front, west winds will increase 
  below the Kern county mountain passes this afternoon and continue 
  into early this evening. Local wind gusts of up to 55 mph could  
  occur in the normally wind prone areas right below the passes. 
  The high resolution models forecast the strongest winds in this  
  region to occur primarily between 2 pm and 9 pm. Otherwise, these  
  downsloping winds will keep the Kern county desert dry.  
   
  Although the cold front will be well south and east of our CWA  
  tonight, a few showers may linger along the valley facing slopes  
  of the Tehachapi mountains into the predawn hours Monday. Low  
  stratus will otherwise blanket the west facing slopes of the  
  Sierra and probably the south end and much of the east side of  
  the San Joaquin Valley tonight into Monday morning. Hopefully the 
  atmosphere will remain well mixed to mitigate dense fog formation 
  over the remainder of the San Joaquin Valley later tonight into 
  Monday morning. Otherwise, Monday will turn out pretty nice with  
  seasonable afternoon temperatures and a good deal of sunshine in  
  most areas, thanks to short wave ridging aloft. Fog could develop 
  in the San Joaquin Valley where skies clear Monday night and  
  persist into Tuesday morning. 
   
  The ridge aloft will flatten over central California Tuesday as  
  a weak upper level trough treks through the Pacific Northwest.  
  Precipitation from this system will likely remain north of our  
  CWA Tuesday. As this trough dives into the Great Basin Tuesday  
  evening, it will produce a northerly flow aloft in its wake over  
  California. If so, it might provide enough atmospheric mixing to  
  keep fog development to a minimum in the San Joaquin Valley  
  Tuesday night. (no promises) 
   
  Night and morning fog in the valley will become more prolific 
  later this week through next weekend as a strong upper level  
  ridge of high pressure over the eastern Pacific builds into  
  California. Dense fog in the San Joaquin Valley could become  
  fairly widespread each night by then and certainly slow travel 
  for morning commuters. Outside of the San Joaquin Valley, the  
  weather will be nice and sunny in the 5 to 7 day period with  
  springlike afternoon temperatures. Thermometer readings could  
  jump into the 70s in the foothill and desert regions each  
  afternoon from Friday through Groundhog Day.
