AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO CA 930 AM PDT WED AUG 3 2005 .SYNOPSIS...MOISTURE IN EASTERLY FLOW ALOFT WILL CONTINUE THUNDERSTORMS IN THE MOUNTAINS AND DESERTS...MAINLY IN THE AFTERNOONS AND EVENINGS. A FEW STORMS COULD DRIFT WEST OF THE MOUNTAINS INTO THE VALLEYS THURSDAY THROUGH THE WEEKEND. A SHALLOW MARINE LAYER WILL CAUSE AREAS OF LOW CLOUDS AND FOG NEAR THE COAST IN THE NIGHTS AND MORNINGS...LINGERING NEAR SOME BEACHES INTO THE AFTERNOONS. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES. OUTFLOW FROM AZ CAUSED A FEW THUNDERSTORMS IN THE ERN PART OF OUR CWFA THIS MORNING BUT THEY HAVE DISSIPATED. LOW CLOUDS AND LOCAL FOG WERE INTO MOST COASTAL AREAS AND WRN INLAND SAN VALLEYS THIS MORNING. THE 12Z NKX SOUNDING HAD A MODERATELY STRONG INVERSION BASED NEAR 1200 FT AND SHOWED MID LEVEL MOISTURE IN ELY FLOW. THE PW WAS 1.12 INCHES...A LITTLE LESS THAN THE LAST COUPLE OF DAYS. HOWEVER...SATELLITE INDICATES HIGHER PW E OF THE MOUNTAINS. EXPECT THUNDERSTORMS IN THE MOUNTAINS AND DESERTS TODAY...DESPITE A LITTLE DRYING. THE MID LEVEL MOISTURE INCREASES THU THROUGH SAT FOR MORE WIDESPREAD AFTERNOON THUNDERSTORMS IN THE MOUNTAINS AND DESERTS WITH A SMALLER CHANCE AT NIGHT. ELY FLOW WILL ALSO INCREASE THROUGH THE MID LEVELS AND THIS COULD CAUSE A FEW STORMS TO DRIFT W OF THE MOUNTAINS INTO THE INLAND VALLEYS EACH DAY. THE MARINE LAYER WILL SHRINK AS THE HI BUILDS OVER THE SW AND DUE TO THE INCREASING MONSOONAL FLOW. EXPECT WARMING IN THE COASTAL AREAS. RELATIVELY MINOR TEMP CHANGES INLAND...ALTHOUGH THE EXACT DISTRIBUTION OF CLOUD COVER AND RH WILL HAVE THE MOST IMPACT ON LOCAL TEMPS. LONGER RANGE PROGS INDICATE THE ELY FLOW ALOFT WEAKENING SUN AND TURNING MORE SLY THROUGH THE MIDDLE OF NEXT WEEK. THIS SHOULD KEEP MOST THUNDERSTORMS CONFINED TO THE MOUNTAINS AND DESERTS. OTHERWISE...NOT MUCH CHANGE. && .AVIATION...COASTAL CLOUD BASES ARE AROUND 600-1200 FEET AND TOPS AROUND 1800 FEET. CLEARING OF THE MARINE LAYER CLOUDS WILL OCCUR BY 17Z AND SOME BEACHES WILL CLEAR. THE MONSOON CONTINUES...SO MORE THUNDERSTORMS OVER THE MOUNTAINS AND DESERTS TODAY. THE MARINE LAYER IS EXPECTED TO GO MORE SHALLOW TONIGHT AND THAT WILL MEAN COASTAL CLOUD COVERAGE MORE CONFINED TO THE COAST WITH LOWER BASES...TOPS AND VISBYS...AND EARLIER CLEARING THU MORNING. .SGX WATCHES/WARNINGS/ADVISORIES...NONE. && PUBLIC...ATKIN AVIATION...MM
