SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 1020 PM PDT MON MAY 27 2013 ...UPDATED AVIATION DISCUSSION... .SYNOPSIS... STRONG...GUSTY AND POTENTIALLY DAMAGING WINDS WILL AFFECT THE MOUNTAIN...DESERTS...AND THE SANTA BARBARA SOUTH COAST THROUGH EARLY WEDNESDAY MORNING. SOME HIGH CLOUDS WILL LINGER THROUGH TUESDAY MORNING WITH THE PASSAGE OF A WEAK TROUGH. HIGH PRESSURE WILL BRING A WARMING TREND TO THE AREA FROM WEDNESDAY THROUGH THE WEEKEND. && .UPDATE... WINDS CONTINUE TO DEVELOP ACROSS THE AREA THIS EVENING...WITH DAMAGING WIND GUSTS OCCURRING ALREADY IN THE LOS ANGELES COUNTY MOUNTAINS AND SUSTAINED WINDS GREATER THAN 40 MPH ACROSS SOUTHERN SANTA BARBARA COUNTY. HIGH WIND WARNINGS REMAIN IN EFFECT FOR NOW AS MUCH THERMAL SUPPORT STILL HAS TIME TO DEVELOP LATER TONIGHT. KSBA-KBFL AND KLAX-KBFL GRADIENTS SHOULD TIGHTEN FURTHER TONIGHT...POSSIBLY BRINGING STRONGER NORTH WINDS TO THE AREA. MAIN CONCERN AT THIS POINT IS FOR THE SANTA CLARITA VALLEY AS LOCALLY GUSTY WINDS HAVE ALREADY DEVELOPED IN THE HILLS. LOCAL 4-KM WRF SOLUTIONS SUGGEST THAT WINDS SHOULD STRENGTHEN OVER THE SANTA CLARITA VALLEY LATER TONIGHT...BUT 00Z NAM-WRF SOLUTIONS ARE A BIT WEAKER WITH THE WINDS FOR THIS AREA. AN ADVISORY IS BEING CONSIDERED FOR THE SANTA CLARITA VALLEY AT THIS TIME...BUT AN ISSUANCE WILL BE DELAYED FOR NOW TO ALLOW MORE DATA TO ARRIVE. ONLY UPDATES TO THE PACKAGE WERE TO ADD MOSTLY CLOUDY SKIES FOR THE AREA AS THERE IS STILL PLENTY OF CLOUDINESS UPSTREAM. && .PREV DISCUSSION... SHORT TERM...MARINE LYR CLOUDS HAVE BEEN SPOTTY AT BEST THE LAST FEW DAYS AND THIS PATTERN EXPECTED TO CONTINUE FOR THE NEXT SEVERAL DAYS. MARINE INVERSION BASED AROUND 2200 FT THIS MORNING. THIS MAY DROP SOME FOR NORTHERN AREAS BEHIND THE TROF BUT COULD DEEPEN IN THE SAN GABRIEL VALLEY. IN ANY CASE, WITH A WEAK INVERSION IN PLACE IT WON'T BE A SOLID MARINE LYR COVERAGE SO PARTLY TO MOSTLY CLOUDY FOR LA COUNTY SHOULD SUFFICE FOR LATE TONIGHT AND TUE MORNING. MID AND HIGH CLOUDS SHOULD BE WELL PAST THE AREA BY NOON TUESDAY LEAVING MOSTLY SUNNY/CLEAR SKIES THROUGH THU AND BEYOND. A RIDGE BUILDING ACROSS THE AREA WILL LOWER AND STRENGTHEN THE INVERSION BUT MODELS CONTINUE TO INDICATE MINIMAL MARINE LYR DEVELOPMENT THROUGH THU. DAYTIME TEMPS EXPECTED TO JUMP A GOOD 5 DEGREES FOR MOST AREAS WED AND ANOTHER 5 DEGREES THU, PUSHING VALLEY HIGHS IN THE LOWER 90S AND COASTAL AREAS IN THE 70S TO LOWER 80S. LONG TERM...PRETTY WARM PERIOD ON TAP THIS COMING WEEKEND, THE PEAK OF WHICH IS EXPECTED TO BE SATURDAY. THE COMBINATION OF RIDGING ALOFT AND WEAK OFFSHORE FLOW SHOULD PUSH INLAND HIGHS TO OR LOCALLY EXCEEDING 100 WHILE COASTAL AREAS ARE PRETTY WARM AS WELL. THESE TEMPS WILL BE FLIRTING WITH DAILY RECORDS IN SOME AREAS. AGAIN, MINIMAL MARINE LYR CLOUDS EXPECTED. && .AVIATION...28/0520Z... OVERALL...MODERATE CONFIDENCE IN 06Z TAF PACKAGE. MID/HIGH CLOUDS THAT WERE ASSOCIATED WITH WEAK FRONTAL SYSTEM ARE NOW MOVING EAST OF THE AREA. SO...OVERNIGHT...GENERAL VFR CONDS ARE EXPECTED ACROSS MOST AREAS. THERE IS A CHANCE OF SOME MVFR CIGS ACROSS THE LAX BASIN OVERNIGHT...AND SOME MVFR/IFR CIGS ALONG THE CENTRAL COAST. BIG ISSUE WILL BE THE WINDS. THE NORTHWESTERLY WINDS SHOULD PICK UP OVERNIGHT ACROSS THE MOUNTAINS...RESULTING IN SOME LLWS/TURBULENCE ISSUES AT KSBA AND POSSIBLY KVNY/KBUR. TUESDAY AFTERNOON...THE WINDS WILL PICK UP ACROSS THE ANTELOPE VALLEY...AND MVFR VSBYS RESTRICTIONS IN BLOWING DUST/SAND WILL BE POSSIBLE. KLAX...MODERATE CONFIDENCE IN 06Z TAF. THERE IS A 40% CHANCE THAT FORECASTED MVFR CONDS WILL NOT DEVELOP OVERNIGHT. KBUR...MODERATE CONFIDENCE IN 06Z TAF. THERE IS A 30% CHANCE OF MVFR CIGS DEVELOPING BETWEEN 11Z AND 16Z. THERE MAY BE SOME LLWS AND TURBULENCE ISSUES LATE TONIGHT. && .LOX WATCHES/WARNINGS/ADVISORIES... HIGH WIND WARNING (SEE LAXNPWLOX). WIND ADVISORY (SEE LAXNPWLOX). GALE WARNING (SEE LAXMWWLOX).
