AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
925 AM PDT WED SEP 19 2007

.DISCUSSION...MINOR CHANGES TO TEMPERATURES FOR TODAY AS THE
COLDER AIR WILL ARRIVE AT THE SOUTH END OF THE SAN JOAQUIN VALLEY
A LITTLE LATER THAN PREVIOUSLY EXPECTED. OVER MUCH OF THE AREA
WILL BE NOTICEABLY COOLER AS A VERY DEEP MARINE LAYER IS LIFTED AND
PUSHED INTO THE INTERIOR BY A VIGOROUS SHORTWAVE TROUGH THAT IS
NOW DEVELOPING OVER THE BAY AREA. WIND PROFILERS SHOW A ROBUST
20-35 KNOTS OF WIND AT 1000-2000 FEET ABOVE THE SURFACE. SPEAKING
OF THE SHORTWAVE, SATELLITE IMAGERY SHOWS A RAPID DEVELOPMENT IN A
TEXT BOOK BAROCLINIC LEAF. THIS DEVELOPMENT WILL HELP DIG THE
TROUGH DOWN THE COAST AND OPEN THE DOOR EVEN WIDER FOR THE LOW TO
MOVE SOUTH. WINDS HAVE KICKED UP OVER THE KERN COUNTY DESERT AS
THE ONSHORE GRADIENT HAS INCREASED AND THE MARINE LAYER HAS
SPILLED INTO THE DESERTS. WILL MATCH WFO OXNARD AND ISSUE AND WIND
ADVISORY FOR TODAY THROUGH MIDNIGHT FOR ZONES 98-99. BEYOND
TONIGHT, THE LOW IS CERTAINLY ON TRACK TO MOVE INTO CENTRAL
CALIFORNIA, AND IT WILL REACH A POSITION OVER THE CENTRAL COAST BY
MID DAY THURSDAY. STILL LOTS OF COLD AIR AVAILABLE AND I HAVE
REINTRODUCED THE THUNDERSTORM THREAT TO THE WEST SIDE OF THE SAN
JOAQUIN VALLEY. STILL LOOKS VERY ACTIVE THROUGH SATURDAY AND I
WILL ADDRESS THIS IN DETAIL ON THE AFTERNOON DISCUSSION. GOTTA GO.

...MUCH COOLER WITH RAIN...MOUNTAIN SNOW...AND WIND WEDNESDAY NIGHT
THROUGH SATURDAY FOR THE CENTRAL CALIFORNIA INTERIOR...

THE FIRST SIGNIFICANT WEATHER SYSTEM OF THE SEASON IS CONTINUING
TO TAKE SHAPE OVER THE PACIFIC NORTHWEST TODAY AND IT IS FORECAST
TO MOVE SOUTH INTO THE CENTRAL CALIFORNIA INTERIOR BEGINNING LATE
TONIGHT AND LINGER THROUGH FRIDAY.

FORECAST MODELS HAVE COME INTO MUCH BETTER AGREEMENT IN
PROJECTING THAT THE CANADIAN LOW WILL DROP SOUTHWARD INTO
NORTHERN CALIFORNIA BY LATE TODAY...REACHING CENTRAL CALIFORNIA
BY MID DAY ON THURSDAY. THE MODELS THEN DIVERGE IN THEIR SOLUTIONS
CONCERNING WHERE THE UPPER LOW WILL TRACK ON FRIDAY AND INTO SATURDAY.
SOME OF THE GUIDANCE IS INDICATING A MORE WESTWARD TRACK OFF THE
COAST...WHICH WOULD MEAN A DRIER FORECAST FOR MOST OF THE
REGION...ESPECIALLY THE SIERRA. THIS IS MAINLY DUE TO THE MOISTURE
REMAINING NEAR THE CENTER OF THE CIRCULATION AND WOULD BE CONFINED
TO THE COASTAL REGION WHERE LOCALLY HEAVY AMOUNTS OR RAIN COULD
OCCUR. SOME OTHER GUIDANCE IS BRINGING THE UPPER LOW CENTER RIGHT
ALONG THE COAST AND THIS WOULD BE FAVORABLE FOR MOISTURE TO MAKE
IT INTO THE VALLEY AND POSSIBLY INTO THE SIERRA. AND THE FINAL
SOLUTION IS THE UPPER LOW WOULD TRACK ALONG THE SIERRA AND WOULD
REMAIN COMPLETELY MOISTURE STARVED AND WOULD ONLY BRING SOME ISOLATED
SHOWERS TO THE MOUNTAINS. CONFIDENCE IS STILL PRETTY LOW AT THIS
TIME ON WHICH TRACK THE UPPER LOW WILL TAKE BEYOND THURSDAY. WE ARE
TRENDING THE FORECAST TO INDICATE IT WILL TRACK RIGHT ALONG THE
COAST AND WILL BRING SOME PRECIPITATION INTO THE REGION. THE UPPER
LOW IS NOW FORECAST TO EXIT THE REGION BY FRIDAY NIGHT AND
CLEARING WOULD BE IN TIME FOR WEEKEND ACTIVITIES.

RIGHT NOW...THE SYSTEM IS MOISTURE STARVED AND MAY NOT HAVE
ENOUGH MOISTURE TO PRODUCE ANY SIGNIFICANT PRECIPITATION TONIGHT
ACROSS THE REGION...HOWEVER WE HAVE PUT IN A THREAT OF RAIN AND
HIGH MOUNTAIN SNOW OVER THE SIERRA NEVADA AND OVER MERCED
COUNTY TONIGHT...THEN AS THE LOW MOVES SOUTHWARD...POSSIBLY
TOWARDS POINT CONCEPTION ON THURSDAY...A MORE WIDESPREAD THREAT
OF LIGHT RAIN SHOWERS MAY OCCUR...BUT MAINLY ALONG THE WEST SIDE
OF THE VALLEY. THE LOW IS THEN FORECAST TO LINGER OFF THE COAST NEAR
POINT CONCEPTION FRIDAY AND BEGIN TO MOVE NE FRIDAY NIGHT AND THIS
WILL SHIFT THE THREAT OF PRECIPITATION SOUTHWARD INTO THE KERN
COUNTY MOUNTAINS AND DESERTS...AS WELL AS THE SOUTHERN SIERRA
NEVADA. ON THE SOUTH FACING SLOPES OF THE KERN COUNTY
MOUNTAINS...LOCALLY HEAVY RAIN WILL BE POSSIBLE FRIDAY AND FRIDAY
NIGHT.

THIS STORM SYSTEM HAS PLENTY OF COLD AIR TO WORK WITH AND
TEMPERATURES WILL BE MUCH COLDER OVER THE ENTIRE AREA. HIGH
TEMPERATURES ON THURSDAY AND FRIDAY WILL BE AS MUCH AS 20 DEGREES
LOWER THAN TODAY AND SNOW IS POSSIBLE IN THE MOUNTAINS ABOVE 6500
FEET. AS THE COLDER AIR ARRIVES...WINDS WILL BE ON THE INCREASE
AND VERY WINDY CONDITIONS ARE LIKELY OVER THE SIERRA CREST...THE
KERN COUNTY MOUNTAINS AND DESERTS TODAY THROUGH THURSDAY.

ALTHOUGH THE CALENDAR SAYS LATE SEPTEMBER...HIKERS...CAMPERS AND
OTHER OUTDOOR ENTHUSIASTS SHOULD BE PREPARED FOR WINTER-LIKE
CONDITIONS AND PREPARE ACCORDINGLY.

LISTEN TO NOAA WEATHER RADIO...OR YOUR FAVORITE NEWS SOURCE...FOR
UPDATES ON THIS SITUATION.
