AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
900 AM PDT MON SEP 6 2010
.SYNOPSIS...
LOW PRESSURE OVER THE WEST WILL CONTINUE TO BRING COOL WEATHER 
THROUGH THURSDAY ALONG WITH MORE EXTENSIVE LOW CLOUDS AND FOG DURING 
THE NIGHTS AND MORNINGS WEST OF THE MOUNTAINS. IT WILL BE LOCALLY 
WINDY AT TIMES IN THE MOUNTAINS AND DESERTS. HIGHER PRESSURE WILL 
RETURN TOWARD THE WEEKEND BRINGING WARMER WEATHER AND LESS LOW 
CLOUDINESS.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
AN UPPER LEVEL TROUGH OF LOW PRESSURE DEEPENED THE MARINE LAYER AND 
SPUN UP AN EDDY THIS MORNING. THAT HAS ALLOWED THE LOW CLOUDS TO 
ENTER THE INLAND EMPIRE IN WEST AND SOUTH PORTIONS. THIS STRONGER 
MARINE INFLUENCE WILL MAKE THIS LABOR DAY COOLER THAN AVERAGE WEST 
OF THE MOUNTAINS AND CLOSE TO AVERAGE IN THE MOUNTAINS AND DESERTS. 
THE EDDY AND THE STRENGTH OF THE MARINE INVERSION WILL MAKE IT 
DIFFICULT FOR THE CLOUDS TO CLEAR IF AT ALL AT THE BEACHES THIS 
HOLIDAY. THIS TROUGH MOVES THROUGH THE WEST TODAY...BUT A WEAK 
TROUGH PATTERN WILL REMAIN TUESDAY. ON WEDNESDAY AND THURSDAY A 
DEEPER TROUGH DROPS DOWN THE WEST COAST AND SLOWLY MOVES THROUGH 
CALIFORNIA. THIS WILL BRING COASTAL CLOUDS UP AND TEMPERATURES DOWN 
EVEN MORE. THESE TROUGHS WILL ALSO BRING GUSTY WINDS TO THE MOUNTAIN 
PASSES AND ADJACENT DESERTS EACH AFTERNOON AND EVENING...BUT WINDS 
WILL BE STRONGEST WEDNESDAY. STARTING FRIDAY THE TROUGH MOVES OUT 
AND SOME WEAK RIDGE PATTERN TRIES TO DEVELOP. THIS WOULD BRING OUR 
WEATHER BACK TO SOMETHING MORE SEASONAL NEXT WEEKEND.
&&
.AVIATION...
061500Z...COASTAL EDDY CONTINUES THROUGH TUE. MARINE LAYER ABOUT 
2200 FT AND RISING. EXPECT IT TO BE ABOUT 2500 FT PLUS TONIGHT 
THROUGH TUESDAY MORNING. BASES AROUND 1500 FT MSL THIS 
MORNING...ABOUT 2K FT TONIGHT OR TUE MORNING. LOCAL VSBY 3-5SM 
INLAND MORNINGS. STRATUS CLEARING SBD/RIV INLAND VALLEYS BY 16-17Z 
AND TO THE COAST BY 19-20Z. STRATUS WILL REMAIN ALONG THE COAST WITH 
AREAS OF BROKEN STRATUS IN THE COASTAL AREAS AND MAY AFFECT SOME 
COASTAL AIRPORTS THROUGH AFTERNOON. STRATUS WILL MOVE INTO THE 
COASTAL AREAS MID TO LATE AFTERNOON WITH COASTAL AIRPORTS BECOMING 
OVERCAST BY LATE AFTERNOON. NOT MUCH CLEARING IN THE COASTAL AREAS 
TUESDAY IF AT ALL WITH LATER CLEARING INLAND.
