  Area Forecast Discussion 
  National Weather Service Hanford CA 
  310 AM PDT Sun Apr 3 2022 
  .SYNOPSIS...Temperatures will remain well above normal today. A 
  slight cooling trend will take place on Monday with breezy  
  conditions this evening through Monday morning. A sharp wamring  
  trend will take place later this week with temperatures rising to 
  around 20 degrees above normal Thursday and Friday with record  
  high temperatures likely.  
  .DISCUSSION...IR imagery showing abundant high clouds streaming 
  over central CA this morning ahead of an upper trough which is  
  approaching the western CONUS coast. The trough is progged by the 
  SREF to push through our area later today which will result in 
  breezy to windy conditions across portions of the Kern County  
  Deserts this evening through early Monday. A Wind Advisory remains 
  in effect for the Mojave Desert Slopes and the Mojave Desert area 
  in Kern County between 300 pm PDT this afternoon and 800 am  
  Monday. While moisture is limited with this system, instability  
  will be sufficient enough for a slight chance of showers this  
  afternoon over the higher elevations of the Sierra Nevada south of 
  Kings Canyon. The other impact that this system will be a slight  
  cooling trend across the area with low temperatures on Monday  
  morning being 3-6 Deg F low that this morning at most locations  
  and daytime highs being slightly lower at most locations despite  
  clearing skies by Monday. 
  SREF is continuing to indicate a strong upper ridge building into 
  CA on Tuesday and Wednesday. This will result in mainly clear 
  skies, dry weather and noticable warming trend across the area 
  with daytime temepratures expected to be around 15 Deg F above  
  normal by Wednesday. 
  Medium range ensemble means are showing the ridge strengthening  
  further later in the week with 500 mb heights progged to be around 
  585 dm. This will result in near record daytime temperatures  
  across our area on Thursday and Friday. Latest NBM probabilistic 
  guidance is indicating a 75 to 90 percent chance of high 
  temperatures exceeding 90 Deg F and a 30 to 50 percent chance of 
  high temepratures exceeding 95 Deg F on Thursday and again on  
  Another upper trough is progged to push through CA next weekend  
  which will result in a cooling trend across our area although  
  temperatures are expected to remain above climatological normals.  
  Latest NBM probabilistic guidance continues to indicate the  
  chance of precipitation across our area next weekend are less  
  than 10 percent. 
  .AVIATION...Areas of MVFR visibility in blowing dust in the Kern  
  County Deserts after 18Z today. Areas of MVFR and local mountain 
  obscuring IFR between 20Z today and 03Z Monday in showers over the 
  Sierra Nevada south of Kings Canyon. Otherwise, VFR conditions  
  will prevail across the Central CA interior through at least the  
  next 24 hours.
