000 FXUS66 KLOX 291048 AFDLOX SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 330 AM PDT TUE JUL 29 2014 .SYNOPSIS... THERE WILL BE A SLIGHT CHANCE OF THUNDERSTORMS AND SHOWERS THIS EVENING AND AGAIN WEDNESDAY AFTERNOON AND EVENING FOR VENTURA AND LOS ANGELES MOUNTAINS AND DESERTS IN A MOIST MONSOON FLOW. THE TEMPERATURES INTO NEXT WEEK WILL BE ABOVE NORMAL WITH THE WARMEST DAY THIS FRIDAY. && .SHORT TERM (TODAY-THU)... THE MARINE LAYER IS ABSENT SOUTH OF POINT CONCEPTION AND HAS ONLY MADE LIMITED INROADS ACROSS THE CENTRAL COAST. THIS IS LARGELY DUE TO THE WEAK ONSHORE FLOW WHICH IS TRENDING OFFSHORE. THE MAIN CLOUD EQUATION WILL BE DRIVEN BY SOME HIGH LEVEL CLOUDS DRIFTING UP FROM THE DISSIPATING TROPICAL STORM HERNAN. BUT THIS WILL JUST MAKE FOR PARTLY CLOUDY SKIES. NOT ENOUGH CLOUDS OR MARINE LAYER HOWEVER TO REALLY AFFECT TEMPERATURES AND IT WILL BE ANOTHER WARM DAY WITH PLENTY OF UPPER 90S IN THE VLYS AND TRIPLE DIGITS IN THE DESERTS AND INTERIOR SECTIONS. A LITTLE EDDY WILL SPIN UP TONIGHT AND THIS SHOULD BRING SOME LOW CLOUDS TO THE LA COUNTY COAST AS WELL AS THE CENTRAL COAST. THERE IS A CHANCE THAT THE HIGH LEVEL CLOUDS WILL DISRUPT THE STRATUS FORMATION BUT RIGHT NOW IT LOOKS LIKE THE CLOUDS WILL NOT BE THICK ENOUGH TO DO THIS. IT WILL BE A LITTLE MORE CLOUDY ON WEDNESDAY AS MORE OF HERNON WAFTS NORTHWARD. OPTIMISTS WILL CALL THE SKIES PARTLY CLOUDY AND PESSIMISTS WILL SEE IT AS MOSTLY CLOUDY. THERE WILL BE ENOUGH LOWER LEVEL MOISTURE TO BRING A RISK OF DESERT OR MTN TSTMS...BUT THERE MAY BE TOO MUCH CLOUDINESS TO ALLOW FOR INITIATION SO FOR NOW WILL ONLY GO FOR A SLIGHT CHC. THE CLOUDS WILL KNOCK A COUPLE DEGREES FROM THE AFTERNOON HIGHS. ON THURSDAY THE UPPER HIGH WILL BE CENTERED OVER SOUTHEAST AZ. CALIFORNIA WILL BE UNDER DRY SW FLOW AND THIS WILL END THE TSTMS CHC. THERE WILL BE SOME CLOUDS IN THE SKY BUT NOT ENOUGH TO CALL IT PARTLY CLOUDY. MAX TEMPS WILL BE VERY SIMILAR TO WEDNESDAY AND IN FACT TO TODAY. .LONG TERM (FRI-MON)... UPPER HIGH SITS BETWEEN AZ AND NM THROUGH THE PERIOD. A WEAK TROF SLOWLY WORKS ITS WAY DOWN THE EAST PAC THROUGH THE PERIOD. THIS WILL INCREASE THE MARINE LAYER AND THE ONSHORE FLOW. SO LOOK FOR A LITTLE MORE CLOUDS AND COOLER TEMPS ACROSS THE COASTS BUT NOT MUCH CHANGE INLAND. THE ONLY OTHER THING OF NOTE IS THAT THERE WILL BE A PRETTY GOOD SUNDOWNER THU NIGHT AND FRIDAY MORNING ALONG WITH WEAKER NORTH WINDS THROUGH THE OTHER MOUNTAIN AREAS. && .AVIATION... 29/0530Z EXPECT WIDESPREAD IFR TO LIFR CIGS TO DEVELOP OVERNIGHT ON THE CENTRAL COAST AND IN THE SANTA YNEZ VALLEY. S OF PT CONCEPTION...EXPECT LOW CLOUDS TO HAVE A DIFFICULT TIME FORMING TONIGHT...BUT CONFIDENCE IS LOW...ESPECIALLY NEAR THE IMDT COAST AT AIRPORTS LIKE KLAX AND KLGB. FAST CLEARING OF LOW CLOUDS BY MID MORNING ON TUE. KLAX...LOW CONFIDENCE IN THE 06Z TAF. THERE IS A 40 PERCENT OF IFR TO LIFR CIGS BETWEEN 09Z AND 16Z. KBUR...HIGH CONFIDENCE IN THE 06Z TAF WITH VFR CONDITIONS THROUGH THE PERIOD. && .MARINE... 29/300 AM PDT SMALL CRAFT ADVISORY CONDITIONS ARE EXPECTED AT TIMES ACROSS THE OUTER WATERS THROUGH FRI.
