AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 PM PDT SUN AUG 7 2005

.SYNOPSIS...MOISTURE FROM THE SOUTHEAST WILL CONTINUE TO BRING
THUNDERSTORMS TO THE MOUNTAINS AND DESERTS...MAINLY IN THE
AFTERNOONS AND EVENINGS. A SHALLOW MARINE LAYER WILL CAUSE AREAS OF
LOW CLOUDS AND FOG NEAR THE COAST IN THE NIGHTS AND MORNINGS.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

LOW CLOUDS AND LOCAL FOG ALONG THIS COAST THIS EVENING STARING TO
MOVE LOCALLY INLAND. BASE OF THE INVERSION ABOUT THE SAME AS
YESTERDAY AT THIS TIME...NEAR 1400FT. PW ESSENTIALLY UNCHANGED
FROM YESTERDAY AT 1.90 INCHES...ATMOSPHERE CONTINUES VERY MOIST.

TIME CROSS SECTION COMPUTER MODELS SHOW LITTLE CHANGE THOUGH MUCH OF
THE UP COMING WEEK AS THE MONSOON CONTINUES. EXPECT ANOTHER VERY
ACTIVE CONVECTIVE DAY MONDAY WITH FLASH FLOOD PRODUCING
THUNDERSTORMS IN THE MOUNTAINS AND DESERTS. SOME OF THESE STORMS
COULD BE SEVERE. THE FLOW ALOFT WILL REMAIN LIGHT BUT ABUNDANT
MOISTURE WILL CONTINUE FOR MORE THUNDERSTORMS EACH DAY...MAINLY IN
THE MOUNTAINS AND DESERTS DURING THE AFTERNOONS AND EVENINGS THROUGH
THE WEEK. THE STRONG UPPER HIGH OVER THE SW WILL KEEP THE MARINE
LAYER SHALLOW AND MOSTLY CONFINED TO THE COASTAL AREAS...WITH QUICK
BURN OFF EXCEPT AT THE IMMEDIATE COAST. MINOR TEMP CHANGES IN MOST
AREAS...HOWEVER THE MARINE LAYER AND THE EXACT DISTRIBUTION OF
MONSOONAL CLOUD COVER AND RH WILL HAVE THE GREATEST IMPACT ON LOCAL
TEMPS.

LONGER RANGE PROGS INDICATE THE UPPER HIGH WILL WEAKEN AND SHIFT
EAST FOR A LITTLE DECREASE IN THE MONSOONAL MOISTURE AND ASSOCIATED
THUNDERSTORM ACTIVITY ABOUT FRIDAY. HOWEVER...EACH MODEL RUN LESSONS
THE DRYING SO ANY BREAK MAY BE MINOR IF AT ALL. THE MARINE LAYER MAY
ALSO INCREASE A LITTLE BRINGING MORE CLOUDS AND COOLER DAYS TO THE
COASTAL AREAS.

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS DIMINISHED 23-02Z...HOWEVER UNSTABLE
AIRMASS WILL BRING YET ANOTHER ROUND OF THUNDERSTORMS BY MONDAY.
LARGE CONVECTIVE COMPLEX RECENTLY FORMING OVER SW AZ COULD SEND AN
OUTFLOW BOUNDARY INTO DESERTS AND MTS LATER TONIGHT AND TRIGGER SOME
NOCTURNAL STORMS...WILL WATCH CLOSELY FOR THIS.

OTHERWISE EXPECT SCATTERED TSTMS BY MON AFTN. A FEW STRONGER STORMS
WILL BRING A THREAT OF STRONG GUSTY SURFACE WINDS...HAIL AND TOPS TO
50000 FT. MOST ACTIVITY WILL BE OVER MTS/DESERTS HOWEVER A FEW
STORMS POSSIBLE IN THE INLAND VLYS PARTICULARLY NEAR HMT/RIV/BUO.

THE MARINE LAYER REMAINS PERSISTENT NEAR COAST WITH BASES AROUND
800-1200 FT MSL AND TOPS ABT 1500 FT. MID/HI CLOUDS HAVE DISRUPTED
THE STRATUS SLIGHTLY...BUT STILL EXPECT CEILINGS TO AFFECT COASTAL
AIRPORTS NEAR 10-16Z. AREAS OF STRATUS WILL LINGER NEAR BEACHES AND
IMMEDIATE COAST INTO MON AFTN.

&&

.SGX WATCHES/WARNINGS/ADVISORIES...
FLASH FLOOD WATCH IN EFFECT FOR THE MOUNTAINS AND DESERTS FROM 10 AM
MONDAY TO 8 PM MONDAY. SEE LAXFFASGX.
