 AREA FORECAST DISCUSSION
 NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
 324 PM PST TUE NOV 24 2009
 
 
 
 .SYNOPSIS...HIGH PRESSURE DOMINATES FOR THE NEXT COUPLE OF DAYS
 RESULTING IN MOSTLY CLEAR SKIES AND PATCHY MORNING FOG. A CHANGE
 IN STORE LATER IN THE WEEK.
 
 &&
 
 .DISCUSSION...SUNNY AND MILD CONDITIONS PREVAIL ACROSS INTERIOR
 CENTRAL CALIFORNIA BENEATH A RIDGE OF HIGH PRESSURE OVER THE
 WESTERN US. THIS WILL CONTINUE THROUGH THANKSGIVING DAY WITH JUST
 A COUPLE OF DEGREES OF WARMING THROUGH THE PERIOD AS THE RIDGE
 EDGES SLOWLY EAST AHEAD OF AN APPROACHING FRONTAL TROUGH. EXPECT
 CONTINUED SEASONABLY COOL OVERNIGHT LOWS...WITH JUST SOME PATCHY
 MORNING FOG IN THE VALLEY. FOG THIS MORNING WAS CONFINED TO A THIN
 RIBBON ALONG THE CENTER OF THE VALLEY...AND WEAK SHORTWAVE ENERGY
 DROPPING SOUTHWARD ACROSS THE DISTRICT TONIGHT COULD HELP TO
 FURTHER LIMIT FOG DEVELOPMENT FOR TOMORROW MORNING.
 
 LATEST AVAILABLE MODELS ARE SIMILAR IN TIMING OF THE APPROACHING
 SYSTEM...WITH THE TROUGH PROGGED TO REACH NORTHERN PORTIONS OF THE
 FORECAST AREA BY LATE MORNING/EARLY AFTERNOON FRIDAY. THE 12Z ECMWF
 HAS TRENDED A LITTLE SHARPER AND SLOWER WITH THE TROUGH...PAINTING
 SOME LIGHT QPF ACROSS THE DISTRICT FRIDAY NIGHT INTO SATURDAY. FOR
 NOW THE FORECAST CONTINUES TO REFLECT THE IDEA THAT THE BEST
 MOISTURE AND ENERGY WILL REMAIN NORTH OF OUR AREA...KEEPING OUR
 POPS BELOW 15 PERCENT.
 
 TEMPERATURES FRIDAY AND SATURDAY SHOULD DROP TO AROUND CLIMO OR A
 LITTLE BELOW BEHIND THE FRONTAL SYSTEM...THEN RECOVER A FEW
 DEGREES FOR THE FIRST PART OF NEXT WEEK AS HIGH PRESSURE REBUILDS
 OVER THE REGION.
