SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 155 PM PDT WED APR 18 2007 .SHORT TERM (TODAY-SAT)...DECENT NORTHWEST WIND EVENT IN PROGRESS, THOUGH WINDS ARE MAINLY ADVISORY LEVEL IN THE MOUNTAINS. JUST A COUPLE SPOTS GUSTING CLOSE TO WARNING LEVEL. WINDS WILL SHIFT TO THE NORTHEAST OVERNIGHT, RESULTING IN STRONGER WINDS IN SOME PLACES AND WEAKER IN OTHERS, DEPENDING ON THEIR GEOGRAPHIC ORIENTATION. NICE WARMUP EXPECTED THU WITH THE OFFSHORE FLOW. BIG DIFFERENCES IN HIGH TEMPERATURE GUIDANCE BETWEEN THE GFS AND NAM IN THE LA/VTU VALLEYS. NAM IS MUCH WARMER, OBVIOUSLY PICKING UP ON THE NORTHEAST WINDS IN THE MORNING. HOWEVER, A STRONG ONSHORE TREND IN THE AFTERNOON AHEAD OF THE APPROACHING COLD FRONT WILL MAKE ANY WARMUP SHORT-LIVED, ESPECIALLY NEAR THE COAST. TRENDED TEMPS UPWARD, BUT NOT AS HIGH AS THE NAM. MODELS STILL ON TRACK FOR FRI AND CONFIDENCE HAS RISEN TO THE POINT WHERE WEVE INCREASED POPS TO 80 OR GREATER IN MOST AREAS ON FRI. GFS CONTINUES TO RUN ABOUT 6 HOURS AHEAD OF THE NAM, BUT BOTH SHOW ENOUGH LOW LVL SOUTHERLY FLOW TO HELP MAKE THIS POTENTIALLY ONE OF OUR BETTER RAIN PRODUCERS THIS SEASON. THE TWO LIMITATIONS TO THIS SYSTEM ARE LOW PWS AND RAPID MOVEMENT. WERE PROBABLY ONLY LOOKING AT 3-6 HOURS OF RAIN WITH THE FRONT, WITH A FEW SHOWERS AHEAD AND BEHIND THE FRONT. INITIALLY GOING WITH A QUARTER TO HALF INCH OF RAIN MOST AREAS WITH THIS FIRST SYSTEM, AND UP TO AN INCH ALONG THE CENTRAL COAST AND SOUTH FACING MOUNTAIN SLOPES. SHOWERS WILL BE TAPERING OFF QUICKLY FRIDAY AFTERNOON AND EVENING WITH ONLY LINGERING SHOWERS NEAR THE GRAPEVINE OVERNIGHT AND INTO SATURDAY MORNING. THERE IS DECENT COLD AIR WITH THIS SYTEM AND CANT RULE OUT A THUNDERSTORM OR TWO, BUT I DONT SEE THIS BEING A HUGE CONVECTIVE OUTBREAK. LATER SHIFTS CAN INCLUDE THESE IF THEY THINK THAT IT WILL BE A SIGNIFICANT ISSUE. SNOW LEVEL WILL BE PRETTY LOW, LOWERING TO BETWEEN 4500 AND 5000 FEET. THE SHORT DURATION OF THE SYSTEM WILL LIKELY KEEP SNOW TOTALS UNDER WARNING LEVELS, BUT I FULLY EXPECT SNOW ADVISORIES WILL BE REQUIRED BY EITHER LATE TOMORROW NIGHT OR FRIDAY. SATURDAY WILL BE THE NICEST DAY BY FAR OF THE FRI-SUN PERIOD. TEMPS WILL WARM UP 5-10 DEGREES FROM FRIDAY WITH GENERALLY LIGHT WINDS AND MOSTLY SUNNY OR PARTLY CLOUDY SKIES. .LONG TERM (SUN-WED)...STORM NUMBER 2 LOOKING MUCH BETTER TODAY THAN IT DID YESTERDAY. TIMING IS STILL SUNDAY, OR PERHAPS LATE SATURDAY NIGHT FOR THE CENTRAL COAST. THE GFS SHOWS A LITTLE LESS IN THE WAY OF SOUTHERLY FLOW BUT PWS ARE HIGHER. NOT SURPRISING THAT THE GFS IS INDICATING A BETTER RAIN EVENT WITH THIS SECOND SYSTEM JUST BASED ON THE MOISTURE AVAILABILITY. ITS ALSO NOT QUITE AS COLD, MEANING RAINFALL EFFICIENCY WOULD BE BETTER. WENT AHEAD AND INCREASED POPS QUITE A BIT FOR SUNDAY, WITH DRY AND WARMER WEATHER MON-WED. LOOK FOR TEMPS TO REBOUND TO NORMAL OR ABOVE NORMAL LEVELS BY TUE. && .AVIATION...18/2045Z CONDITIONS WILL REMAIN VFR AT ALL AIRFIELDS ACROSS THE FORECAST AREA THROUGH TONIGHT. LOW LEVEL WIND SHEAR WILL AFFECT KSBA...KBUR AND KVNY. KLAX WILL HAVE STRONG WEST TO NORTHWEST WINDS INTO THE EVENING. WINDS WILL DIE DOWN LATER THIS EVENING. SKIES AND VISIBILITIES WILL BE CLEAR. && .LOX WATCHES/WARNINGS/ADVISORIES... HIGH WIND WARNING (SEE LAXNPWLOX). WIND ADVISORY (SEE LAXNPWLOX). GALE WARNING (SEE LAXCWFLOX).
