SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 1050 AM PDT SUN SEP 2 2007 ...UPDATED AVIATION DISCUSSION... .SHORT TERM... EXPANDED EXCESSIVE HEAT WARNING THROUGH LABOR DAY FOR THE LA/VTU COUNTY MOUNTAINS AND VALLEYS...AS WELL AS THE INTERIOR VALLEYS OF SAN LUIS OBISPO COUNTY. TEMPS SHOULD BE A DEGREE OR TWO WARMER IN MOST LOCATIONS...WITH THE EXCEPTION OF SANTA BARBARA AND SAN LUIS OBISPO COUNTY COASTAL AREAS HEATING UP QUITE A BIT FROM YESTERDAY AS LOW LEVEL OFFSHORE FLOW WAS OCCURRING THIS MORNING. PORT SAN LUIS...AVILA BEACH AND SAN LUIS OBISPO SHOULD BE MUCH WARMER TODAY. THE OTHER IMPORTANT ISSUE OF THE DAY WILL BE THE CONVECTION THAT SHOULD OCCUR ONCE AGAIN ACROSS THE LA/VTU COUNTY MOUNTAINS AND ANTELOPE VALLEY. LATEST CONVECTIVE PARAMETERS ARE NOT QUITE AS STRONG AS YESTERDAY...BUT THAT WOULD BE HARD TO TOP WITH K-INDEX VALUES UP INTO THE LOWER 40S YESTERDAY. ALTHOUGH K-INDEX VALUES ARE DOWN FROM YESTERDAY IN THE LOWER TO MID 30S AND LIFTED INDEX ARE NOT QUITE AS BROAD ACROSS THE REGION...PWAT VALUES ARE STILL QUITE HIGH. LATEST GOES SOUNDER PW VALUES ARE ALSO IMPRESSIVE ONCE AGAIN TODAY WITH PW VALUES NEAR 1.5 INCHES. WITH VERY HIGH DEW POINTS SHOWING UP ACROSS VENTURA AND LA COUNTIES THIS MORNING...AND WEAK STEERING WINDS ALOFT...WILL LIKELY GO AHEAD AND ISSUE A FLASH FLOOD WATCH WITHIN THE HOUR FOR THE MOUNTAINS OF LOS ANGELES AND VENTURA COUNTIES AS WELL AS THE ANTELOPE VALLEY FOR THIS AFTERNOON AND EVENING ...FROM PREVIOUS DISCUSSION... HEAT AND THUNDER ARE THE WORRIES TODAY. SOME MDLS SHOWING A 5 DEGREE RISE IN TEMPS BUT THAT MDL USUALLY OVERDOES TEMPS BUT FEEL ALL AREAS WILL BE COUPLE OF DEGREES WARMER THAN YDY. WHICH MEANS THAT IT WILL BE SCORCHING HOT AND HIGH HEAT WARNINGS ARE IN PLACE THROUGH 700 PM. DEW POINTS ARE STILL NEAR 12 K INDEX IS IN THE UPPER 30S AND LIS ARE NEAR ZERO. NO REASON THERE WILL NOT BE THUNDERSTORMS IN THE MOUNTAINS AND AND ANTELOPE VLY AGAIN TODAY. WINDS ALOFT ARE LIGHT AND SHEAR IS QUITE LOW SO FEEL THE MAIN THREAT FROM TODAYS STORMS IS FLASH FLOODING. A SMALL FLY IN THE OINTMENT IS A LARGE OUTFLOW BOUNDARY SHOOTING OUT THUNDERSTORM COMPLEX NEAR YUMA...JUDGING BY ITS MOTION IT LOOKS LIKE IT WILL AFFECT SAN DIEGOS WARNING AREA...BUT HAVE TO WORRY ABOUT 30 MINUTES OF GUSTY EAST WINDS WHICH MIGHT DRIVE COASTAL TEMPS WAY UP. TONIGHT THE STORMS WILL QUICKLY DRY UP BETWEEN 6 AND 7 IN THE EVENING AND ANY PARTLY CLOUDY SKIES WILL SOON CLEAR UP. ANOTHER WEAK SUNDOWNER IN THE 15 TO 25 MPH CATEGORY WILL NOT BE TOO BOTHERSOME BUT WILL KEEP OVER NIGHT LOWS IN THE 80S NEAR THE BREEZY CANYONS. THE UPPER HIGH WEAKENS JUST A TOUCH MONDAY AND THIS SHOULD ALLOW MOST AREAS TO SEE 2 TO 3 DEGREES COOLING. THIS MIGHT NOT BE ENOUGH TO LOWER TEMPS BELOW HEAT WARNING LEVELS. DAY SHIFT WILL HAVE EVALUATE THE HUMIDITIES AND HEAT INDEX NUMBERS. DEW POINTS AND K INDEXES LOOK A LITTLE MORE FAVORABLE FOR THUNDER...AGAIN ALL SIGNS POINT TO A FLASH FLOODING PROBLEM RATHER THAN SEVERE WEATHER. TUESDAY A UPPER TROF PUSHING INTO THE PAC NORTHWEST AND BEATS BACK THE UPPER HIGH AS WELL AS STRENGTHENING THE ONSHORE FLOW. THIS WILL DROP MAX TEMPS 6 TO 8 DEGREES FROM MONDAY AND SHOULD BREAK THE GRIP OF THE HEAT WAVE. THUNDER PARAMETERS ARE STILL FAVORABLE FOR THE DESERT AND MOUNTAINS AND WILL CARRY A SLIGHT CHANCE FOR ON LAST DAY. .LONG TERM... COOLING SHOULD CONTINUE WED AND THU WITH CYCLONIC FLOW AND ONSHORE FLOW. THIS SHOULD BE ENOUGH TO CREATE A MARINE LAYER. EVERYTHING SHOULD BE CLOSE TO NORMALS. BUT...THEN THINGS GET A LITTLE INTERESTING. BOTH GFS AND EC AGREE THAT THERE SHOULD BE SOME SORT OF DISSIPATING TROPICAL SYSTEM SOMEWHERE FAIRLY NEAR TO SOCAL. THE GFS GOES HOG WILD WITH THE CLOUDS AND RAIN AND AM CERTAINLY NOT GOING TO GO THERE YET. IN FACT ONLY TURNED THE SKIES PARTLY CLOUDY FOR NOW. STILL IT BARES MENTIONING THAT THE GFS HAS HAD SIMILAR SOLUTIONS FOR THE PAST FEW RUNS. WILL KEEP WATCHING THIS POTENTIALLY INTERESTING DEVELOPMENT. && .AVIATION... 02/1750Z FOR COASTAL/VALLEY TAF SITES...VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD...WITH TYPICAL AFTERNOON SEA BREEZES. KSBA IS EXPECTED TO HAVE SOME WIND SHEAR THIS EVENING BETWEEN 02Z AND 10Z AS THE SUNDOWNERS ARE EXPECTED TO REDEVELOP.
