AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
241 PM PDT SAT AUG 8 2009

.DISCUSSION...SIGNIFICANT WARMING IS TAKING PLACE ACROSS THE
DISTRICT TODAY AS THE UNSEASONABLY COOL AIRMASS OF THE LAST COUPLE
DAYS IS BEING DISPLACED BY A BUILDING EPAC RIDGE. 24 HOUR TRENDS
REVEAL VALLEY TEMPERATURES ARE RUNNING UP AROUND 5-8 DEGREES AND
ARE ON TRACK TO TOP OUT IN THE UPPER 80S TO LOWER 90S. SUNDAY WILL
SEE SEVERAL MORE DEGREES WARMING WITH TEMPERATURES BACK TO AROUND
SEASONAL AVERAGES. FURTHER WARMING WILL TAKE PLACE INTO EARLY NEXT
WEEK PUSHING VALLEY...LOWER FOOTHILL AND DESERT HIGHS INTO THE
TRIPLE DIGITS AGAIN. 12Z GFS AND ECMWF HAVE COME INTO BETTER
AGREEMENT NOW WITH THE TROUGH MOVING THROUGH THE PACNW BY THE END
OF THE WEEK. THE WEAKER SOLUTION IS NOW ADVERTISED BY BOTH THOUGH
IT DOES BREAK DOWN THE RIDGE ENOUGH OVER CENTRAL CALIFORNIA FOR
SOME NOTICEABLE SYNOPTIC COOLING AS WELL AS BRING IN SOME COOLER
ONSHORE FLOW. SLIGHT COOLING IS FORECAST EACH DAY FROM THURSDAY
THROUGH SATURDAY ENDING WITH NEAR CLIMO TEMPS. A DRY FORECAST
REMAINS AS MODELS HAVE NOT INDICATED ANY INCREASE FROM PREVIOUS
RUNS IN MID LEVEL MOISTURE MOVING TOWARDS THE SOUTHERN SIERRA. BUT
THIS WILL NEED TO BE WATCHED AS A FOUR CORNERS HIGH DOES SET UP
AROUND TUESDAY.
