AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
937 PM PDT MON MAR 15 2010
.SYNOPSIS...
A RIDGE OF HIGH PRESSURE ALONG WITH WARM TEMPERATURES AND DRY
CONDITIONS WILL PREVAIL THROUGH NEXT WEEKEND.
&&
.DISCUSSION...THE HIGH PRESSURE RIDGE OVERHEAD CONTINUES TO
PROVIDE FAIR AND MILD CONDITIONS OVER INTERIOR CENTRAL
CALIFORNIA...WITH JUST SOME MAINLY THIN CIRRUS SPILLING ACROSS
THE DISTRICT. TEMPERATURES THIS AFTERNOON WARMED SEVERAL DEGREES
ABOVE YESTERDAY HIGHS...ESPECIALLY IN THE SOUTH VALLEY WHERE SOME
LOCALES HIT THE 80 DEGREE MARK. EXPECT A SIMILAR TREND IN
OVERNIGHT LOWS AND THE FORECAST FOR TONIGHT LOOKS OK.
SHORTWAVE ENERGY RIDING OVER THE RIDGE BY MIDWEEK SHOULD PROVIDE
JUST A SLIGHT CHANCE FOR SHOWERS OVER THE HIGH SIERRA AND ONLY
SLIGHTLY COOLER TEMPERATURES ACROSS THE DISTRICT...STILL REMAINING
ABOVE CLIMO.
&&
.PREV DISCUSSION... /ISSUED 151 PM PDT MON MAR 15 2010/
DISCUSSION...SUNNY SKIES PREVAIL THIS AFTERNOON AND TEMPERATURES
HAVE WARMED UP UNDER HIGH PRESSURE. SOME CIRRUS IS NOTED BUT THAT'S
ABOUT IT IN THE CLOUD DEPARTMENT. FORECAST MODELS KEEP THE RIDGE
STRONG UNTIL LATE TUESDAY NIGHT AND THEN A WEAK SHORTWAVE TROUGH
IS PROGGED TO MOVE INTO CENTRAL CALIFORNIA WEDNESDAY. THIS FEATURE
WILL BE WEAK AND OTHER THAN SOME CLOUDS AND MAYBE A SLIGHT
COOL DOWN, NO REAL WEATHER AFFECTS WILL BE NOTED. BY THURSDAY AND
ESPECIALLY THURSDAY NIGHT A STRONGER TROUGH OF LOW PRESSURE IS
WELL AGREED UPON BY THE GFS AND ECMWF MODELS TO DROP INTO THE
GREAT BASIN AND "CLIP" THE SIERRA AS IT HEADS QUICKLY TO THE
SOUTHEAST. LATEST MODEL DATA CONTINUES TO SUGGEST A SMALL THREAT
OF SNOW SNOWS NEAR THE SIERRA CREST OF ZONE 96 AND I WILL KEEP
THIS IN THE GRIDS. WINDS WILL LIKELY PICK UP OVER THE KERN COUNTY
MOUNTAINS, EAST SIERRA SLOPE AND THE KERN DESERTS AND TEMPERATURES
WILL COOL DOWN. THE RIDGE OF HIGH PRESSURE IS THEN PROJECTED TO
REBUILD OVER THE REGION FOR THE UPCOMING WEEKEND AND INTO EARLY
NEXT WEEK.
&&
.AVIATION...
VFR CONDITIONS CAN BE EXPECTED ACROSS THE CENTRAL CA INTERIOR
THROUGH 06Z WEDNESDAY.
&&
.AIR QUALITY ISSUES...
NONE
