AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
135 PM PST WED DEC 12 2007

.DISCUSSION...A WEAK UPPER TROUGH DROPPING SOUTH ALONG THE
CALIFORNIA COAST IS BRINGING SOME HIGH CLOUDS TO THE REGION THIS
AFTERNOON. SATELLITE TRENDS INDICATE THAT THE THICKER PART OF THIS
CLOUD MASS WILL SHIFT EAST OF THE SAN JOAQUIN VALLEY TONIGHT AS
THE LOW CONTINUES TO DROP SOUTH. ALTHOUGH SCATTERED TO BROKEN
CIRRUS WILL REMAIN OVER THE VALLEY...DO NOT THINK IT WILL BE
ENOUGH TO PREVENT TEMPERATURES FROM DROPPING BELOW 32 DEGREES IN
PARTS OF THE VALLEY AGAIN TONIGHT. THUS...WILL ISSUE A FROST
ADVISORY FOR THE OVERNIGHT HOURS. THE LAST FEW NIGHTS TEMPERATURES
HAVE DROPPED BELOW FREEZING IN SEVERAL LOCATIONS BEFORE
MIDNIGHT...SO HAVE STARTED TONIGHTS ADVISORY A LITTLE EARLIER.
WITH LITTLE CHANGE IN DEWPOINTS IN THE VALLEY...PATCHY FOG IS ALSO
POSSIBLE.

MODELS ARE IN GENERAL AGREEMENT WITH RIDGING AND SLIGHTLY WARMER
TEMPERATURES FOR FRIDAY INTO SUNDAY. BEYOND SUNDAY THERE CONTINUES
TO BE LESS CONSISTENCY BETWEEN MODELS AND FROM RUN TO RUN WITHIN
THE MODELS. THE 12Z GFS IS NOW FOCUSING THE PRECIP MORE TOWARD
MONDAY NIGHT/TUESDAY MORNING WHILE THE ECMWF BRINGS IN SOME PRECIP
MONDAY BUT IS MUCH WETTER TUESDAY AND TUESDAY NIGHT AND LINGERS
SHOWERS INTO WEDNESDAY. IT CERTAINLY LOOKS LIKE THERE WILL BE
PRECIPITATION SOMETIME IN THE EARLY PART OF THE WEEK. BUT FOR NOW
HAVE CONTINUED TO BROAD BRUSH MONDAY THROUGH WEDNESDAY WITH CHANCE
OF RAIN AND WILL HAVE TO WAIT TO BETTER DETERMINE THE TIMING.

&&

.AVIATION...IN THE SAN JOAQUIN VALLEY...AREAS OF MVFR DUE TO LOWER
