SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 845 PM PST WED JAN 28 2009 ...UPDATED AVIATION DISCUSSION... .UPDATE...LATEST NAM-WRF AND GFS MODEL SOLUTIONS ARE STARTING TO STRENGTHEN THE OFFSHORE FLOW TONIGHT...AND PACKAGE WILL BE UPDATED TO UPGRADE THE LOS ANGELES AND VENTURA COUNTY MOUNTAINS AND THE SANTA MONICA RANGE TO A HIGH WIND WARNING. CURRENT SURFACE GRADIENTS NEAR -6 MB BETWEEN KLAX-KBFL AND KSBA-KBFL ARE SOMEWHAT UNDERDONE BY THE MODELS. NAM-WRF AND GFS HAVE INTENSIFIED 850 AND 950 MB THERMAL GRADIENTS IN THE CURRENT MODELS SOLUTIONS...WITH NAM-WRF 950 MB THERMAL GRADIENTS PEAKING AROUND 11 DEGREES CELSIUS BETWEEN THE ANTELOPE VALLEY AND THE SOUTHERN CALIFORNIA BIGHT. GFS 850 MB THERMAL GRADIENTS ARE EQUALLY IMPRESSIVE DUE TO THE COARSENESS OF THE MODEL...PEAKING AT 7 DEGREES CELSIUS BETWEEN THE MOJAVE DESERT AND THE SANTA BARBARA CHANNEL. GFS AND NAM-WRF BOTH BRING A STRONG AREA OF SUBSIDENCE OVER THE AREA BETWEEN 12Z AND 18Z THURSDAY...AND THIS VERIFIES WELL WITH THE CURRENT WATER VAPOR IMAGERY WITH AREA OF SUBSIDENCE STARTING TO DEVELOP OVER NORTHERN CALIFORNIA. SOME CONCERN THAT WIND ADVISORIES MAY ALSO BE NEEDED FOR THE FOOTHILLS OF SAN LUIS OBISPO AND SANTA BARBARA COUNTY AS LATEST NAM INDICATE SOME STRONGER THERMAL GRADIENTS AT 975 MB AND 950 MB...ALONG WITH A INCREASING STRONGER SURFACE PRESSURE GRADIENT BETWEEN KSMX- KBFL. FOR NOW...NO WIND HEADLINES WILL BE ISSUED FOR THE SAN LUIS OBISPO AND SANTA BARBARA FOOTHILLS...BUT WINDS WILL BE BUMPED UP IN THE CURRENT PACKAGE. LATEST NAM-WRF 950 MB TEMPERATURES INITIALIZED WELL AND CURRENT PACKAGE SEEMS AGREEABLE AS FAR AS TEMPERATURES FOR THURSDAY AND BEYOND FOR AREAS SOUTH OF POINT CONCEPTION. HOWEVER FOR THE CENTRAL COAST WITH SOME STRONGER GRADIENTS DEVELOPING AND OFFSHORE FLOW BEING MUCH STRONGER...UPDATES WILL REFLECT CONCERN FOR A POSSIBLE WARMER DAY ALONG THE CENTRAL COAST BUMPING TEMPERATURES TO NEAR THE 80 DEGREE MARK FOR SOME AREAS. && .PREV DISCUSSION... /ISSUED 345 PM PST WED JAN 28 2009/ SHORT TERM (TODAY-SAT)...INCREASING OFFSHORE FLOW TONIGHT WILL LEAD TO ADVISORY LEVEL NORTHEAST WINDS ACROSS PORTIONS OF VENTURA AND LOS ANGELES COUNTIES THROUGH FRIDAY. MAY EVEN GET SOME PEAK WINDS NEAR 60 AT THE USUAL WINDY SPOTS THROUGH THE HIGHWAY 126 AND 118 CORRIDORS. WINDS SHOULD START DEVELOPING TONIGHT WITH ADVISORY LEVEL WINDS IN THE MOUNTAINS AND VALLEYS BY SUNRISE. HAVE ALSO INCLUDED THE LA/VTU COUNTY COAST IN THE ADVISORY AND WINDS THERE MAY PICK UP BY SUNRISE BUT MORE LIKELY CLOSER TO 9 AM. ELSEWHERE, LOCALLY BREEZY CONDITIONS ARE POSSIBLE, ESPECIALLY THE ANTELOPE VALLEY DURING THE NEXT TWO AFTERNOONS. TEMPS WILL BE ON THE WAY UP WITH 70S AND EVEN SOME LOWER 80S ACROSS THE COAST AND VALLEYS BY FRIDAY. STRONGEST WINDS ARE EXPECTED THURSDAY AS UPPER SUPPORT IS SLIGHTLY WEAKER ON FRIDAY. HOWEVER, GRADIENTS ARE JUST AS STRONG SO IT SHOULD STILL BE QUITE WINDY. OFFSHORE FLOW WEAKENS SAT, BUT DRY AND WARMER THAN NORMAL TEMPS EXPECTED TO CONTINUE. HIGHS WILL BE DOWN A FEW DEGREES SAT BUT STILL WELL ABOVE NORMAL. LONG TERM (SUN-WED)...LITTLE CHANGE SUNDAY. THEN MODELS SHOW A SLIGHT INCREASE IN OFFSHORE FLOW AGAIN EARLY NEXT WEEK. THIS SHOULD RESULT IN A FEW DEGREES OF WARMING MONDAY AND POSSIBLY A RETURN TO MORE WIND ADVISORIES. MODELS DIVERGE TUE-WED WITH THE GFS CONTINUING TO SHOW A CUTOFF LOW SLOWLY APPROACHING THE COAST WHILE THE ECMWF KEEPS IT FARTHER OFFSHORE. THE EC HAS HAD A BETTER TRACK RECORD, PARTICULARLY WITH REGARD TO THESE CUTOFF LOWS SO IM INCLINED TO FAVOR THIS SOLUTION, WHICH WOULD MAINTAIN ABOVE NORMAL TEMPS THROUGH AT LEAST THE MIDDLE OF NEXT WEEK AND CLEAR SKIES. IT ISNT UNTIL AT LEAST NEXT WEEKEND BEFORE THE EC BRINGS THE TROF TO THE COAST, BUT THE GFS SOLUTION WOULD CERTAINLY RESULT IN AN EARLIER COOL DOWN AND CHANCE OF RAIN. && .AVIATION...29/0440Z.
