 AREA FORECAST DISCUSSION
 NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
 937 PM PST MON NOV 23 2009
 
 .SYNOPSIS...SKIES WILL BE MOSTLY CLEAR FOR THE NEXT COUPLE DAYS 
 EXCEPT FOR LATE NIGHT AND EARLY MORNING VALLEY FOG. 
 
 
 &&
 
 
 .DISCUSSION...CLEAR SKIES DOMINATE THIS EVENING. FORECAST PROBLEM
 FOR THE VALLEY IS HOW LONG THEY WILL REMAIN CLEAR. WILL PROBABLY
 SEE SOME LOW STRATUS EVENTUALLY DEVELOP AFTER MIDNIGHT...BUT
 PROBABLY NOT NEARLY AS EXTENSIVE AS LAST NIGHT. CLEAR SKIES ARE
 ALLOWING TEMPS TO DROP AS WELL...AND EXCEPT FOR THE FAR SOUTH
 END...ARE RUNNING SOME 4-9 DEGS COLDER THAN 9PM YESTERDAY. UPDATED
 MIN TEMPS A BIT TONITE MAINLY VALLEY AND FOOTHILLS. ELSEWHERE
 OVER CENTRAL CA TEMPS ARE UP A FEW DEGS FROM YESTERDAY AS UPPER
 RIDGE SLOWLY MOVES INSIDE 130W.

 .PREV DISCUSSION... /ISSUED 242 PM PST MON NOV 23 2009/ 
 
 STRATUS DECK HAS ALMOST ENTIRELY DISSIPATED OVER THE VALLEY AT
 THIS TIME. DUE TO A SMALL AREA OF LOW CLOUDS THAT REMAINS NEAR
 MERCED TEMPS HAVE BEEN SLOWEST TO RECOVER THERE. OTHERWISE TEMPS
 THROUGHOUT THE VALLEY ARE GENERALLY AROUND THE SAME AS THEY WERE
 24 HRS AGO. THE REST OF THE FCST AREA IS GENERALLY AT LEAST A FEW
 DEG WARMER WITH MOSTLY CLEAR SKIES...WITH GREATEST WARMING IN THE
 MTNS AND FOOTHILLS...COMPARED TO 24 HRS AGO DUE TO A LACK OF CLOUD
 COVER FOR THE DAY. NOW THAT WE HAVE GENERALLY CLEAR SKIES AND
 LIGHT WINDS...THE POSSIBILITY OF PATCHY FOG OVER THE VALLEY
 REMAINS FOR LATE TONIGHT AND TUE AM.
 
 THE RIDGE OF HIGH PRESSURE OVER THE AREA IS EXPECTED TO CONTINUE
 BUILDING AND BRING WARMING TEMPS TUE THRU THANKSGIVING DAY BEFORE
 GIVING WAY TO A TROUGH ON FRI AND THE REMAINDER OF THE HOLIDAY
 WEEKEND. FCST MODELS ARE IN FAIRLY GOOD AGREEMENT IN MOVING THE
 RIDGE EAST OF THE AREA WITH A TROUGH OVER THE AREA THRU SUN WHILE
 ANOTHER EAST PACIFIC RIDGE BUILDS OFF THE WEST COAST. MODELS
 SOMEWHAT DIFFER ON MOVING THE TROUGH...THE EURO DEPICTS THIS
 TROUGH MORE AS AN INSIDE SLIDER MOVING OVER THE GREAT BASIN.
 ANYHOW...DRY WEATHER IS LIKELY TO CONTINUE WITH TEMPS COOLING BACK
 TO SLIGHTLY BELOW NORMAL FOR FRI INTO SUN. BEYOND THE HOLIDAY
 WEEKEND KEPT TEMPS NEAR CLIMO FOR NOW...DUE TO MORE MODEL
 DISAGREEMENT ON PLACEMENT OF FEATURES.
 
 
 &&
 
 .AVIATION...
 AREAS OF MVFR WITH SOME LOCAL IFR IN BR/FG WILL DEVELOP IN THE SAN 
 JOAQUIN VALLEY OVER THE VALLEY TONIGHT...THEN DISSIPATING AROUND 19Z 
 TUESDAY. OTHERWISE...VFR CONDITIONS WILL PREVAIL ELSEWHERE IN THE 
 CENTRAL CALIFORNIA INTERIOR THROUGH 06Z WEDNESDAY.
 
 &&
 
 .AIR QUALITY ISSUES...
 ON TUESDAY NOVEMBER 24 2009... FIREPLACE/WOOD STOVE BURNING IS
 PROHIBITED IN KERN COUNTY.
