AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA 920 AM PDT FRI AUG 6 2004 .UPDATE...FOR THE CENTRAL CALIFORNIA INTERIOR...THE UPPER-LEVEL SHORT-WAVE TROUGH CONTINUES TO MOVE THROUGH CALIFORNIA THIS MORNING...WITH AN EMBEDDED VORTICITY CROSSING THE NORTHERN PART OF THE STATE. THIS VORTICITY GENERATED SOME MID- AND HIGH-LEVEL CLOUDS AS FAR SOUTH AS YOSEMITE. OTHERWISE...SKIES ARE CLEAR OVER THE HANFORD WARNING/FORECAST AREA. THIS MORNING/S LOW-LEVEL SOUNDING FOR FRESNO IS VERY SIMILAR TO THAT FOR AUGUST 4TH...WHILE THE BAKERSFIELD SOUNDING IS A COUPLE OF DEGREES COOLER. /THE SOUNDINGS FOR AUGUST 5TH WERE NOT AVAILABLE./ AT 15Z...TEMPERATURES ACROSS THE CENTRAL AND SOUTHERN SAN JOAQUIN VALLEY WERE RUNNING DOWN 1-3 DEGREES FROM 24 HOURS EARLIER. THE FORT ORD PROFILER SHOWS THAT THE MARINE LAYER IS FAIRLY WELL MIXED OUT... SO MAY SEE SOME MARINE AIR SPILL OVER THE COASTAL RANGE...HELPING TO COOL THE SAN JOAQUIN VALLEY A COUPLE OF DEGREES. CONVERSELY...THE 12Z MODELS SHOW STRONG RIDGE BUILDING BEGINNING BY THIS AFTERNOON...WITH THE 5880-METER 500-MB HEIGHT LINE RISING FROM JUST SOUTH OF THE TEHACHAPI MOUNTAINS TO OVER FRESNO BY 00Z SATURDAY. WILL HOLD OFF ON ANY CHANGES TO THE FORECAST AT THIS TIME AND MONITOR TEMPERATURE TRENDS FOR POSSIBLE UPDATES LATER THIS MORNING. .FROM PREVIOUS DISCUSSION... .SHORT TERM...FOR THE CENTRAL CALIFORNIA INTERIOR...RATHER DEEP TROUGH FOR EARLY AUGUST CONTINUES TO MOVE INTO NORTHERN CALIFORNIA AS VORT MAX NUMBER TWO MOVES ACROSS THE FAR NORTH. UPSTREAM...YET ANOTHER VORTICITY CENTER IS RACING SOUTHEAST TOWARDS THE COAST AND WILL LIKELY MOVE ACROSS THE NORTH LATER TODAY. ADDITIONAL COOLER AIR ALOFT IS NOTED ON THE FORT ORD PROFILER AS THE TROUGH MOVES THROUGH. SJV WIND PROFILERS AGAIN TONIGHT HAVE QUITE A BIT OF NORTHWEST FLOW IN THE 30-40 KNOT RANGE. IN ADDITION KHNX IS SHOWING 35 KNOTS AT 1000 FEET OFF THE SURFACE. IT WILL BE INTERESTING AGAIN TODAY TO SEE JUST HOW MUCH COLD AIR ADVECTION TAKES PLACE. WILL GO AHEAD AND BASE TODAY/S HIGHS PRETTY MUCH ON THURSDAY/S AS THE OVERALL CHANGE ON THE FT ORD TEMPERATURE PROFILE FROM 24 HOURS AGO IS NOT THAT DIFFERENT. THE ETA AND GFS MODELS ARE IN GOOD AGREEMENT IN SHIFTING THE TROUGH AXIS EASTWARD TONIGHT AND ON SATURDAY REALLY BUILDING THE RIDGE OVER THE AREA. HEIGHTS ARE PROJECTED TO RISE AROUND 30-40 METERS BY SATURDAY AFTERNOON...AND ANOTHER 30 METERS OR SO ON SUNDAY AS WELL. SHOULD SEE QUITE A FEW 100+ TEMPERATURES AT LOWER ELEVATIONS BY THE END OF THE WEEKEND. WHENEVER THE RIDGE BUILDS BACK WEST FROM THE DESERT SOUTHWEST...THE POSSIBILITY OF SUBTROPICAL MOISTURE RETURN ALWAYS ACCOMPANIES IT. AT THIS TIME...IT APPEARS THAT THROUGH SUNDAY...THE MOISTURE WILL STAY SOUTHEAST OF CENTRAL CALIFORNIA. WILL KEEP THE GRIDS AND THE ZONE FORECASTS DRY AT THIS TIME. .LONG TERM...FOR SUNDAY NIGHT THROUGH THURSDAY...GOOD AGREEMENT WITH ALL OF THE MEDIUM RANGE MODELS IN THE 4 TO 7 DAY PERIOD WITH 50H RIDGE CENTERED OVER THE SWRN CONUS. MODELS MAINTAIN DRY SW FLOW ALOFT ACROSS CENTRAL CA THRU AT LEAST WED. HOWEVER...THE GFS HINTS THAT SOME MID LEVEL MOISTURE WILL BECOME ENTRAINED IN THIS FLOW BY DAY 7. WHILE IT IS STILL TOO EARLY TO TELL WHETHER OR NOT THIS WILL LEAD TO ISOLD PM CONVECTION OVER THE HIGH SIERRA THURSDAY...WILL INCREASE PERCENTAGE SKY COVER IN THESE AREAS FOR NOW AND SEE HOW MODELS TREND WITH FUTURE RUNS. TEMPS AVERAGING ABOVE NORMAL THRU THE PERIOD. && .HNX WATCHES/WARNINGS/ADVISORIES...NONE. && SANGER/DUDLEY/DURFEE
