AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO
230 PM PDT SAT JUL 24 2004

.SYNOPSIS...STRONG HIGH PRESSURE ALOFT WILL CAUSE A WARMING TREND WITH
HOT DAYS INLAND EARLY NEXT WEEK. THE MARINE LAYER AND ONSHORE FLOW
WILL CAUSE COASTAL LOW CLOUDS AND FOG IN THE NIGHTS AND MORNINGS...
EXTENDING LOCALLY INLAND AND LINGERING NEAR SOME BEACHES IN THE
AFTERNOONS. LIMITED MOISTURE IN SOUTHEAST FLOW ALOFT WILL BRING SOME
CLOUDS TO THE MOUNTAINS DURING THE AFTERNOONS. GRADUALLY COOLER WITH
AN INCREASING MARINE LAYER DURING THE SECOND HALF OF NEXT WEEK AS THE
HIGH PRESSURE ALOFT WEAKENS.

&&

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

.SHORT TERM...LOW CLOUDS AND FOG WERE INTO ALL COASTAL AREAS...MOST
SAN INLAND VALLEYS AND FAR WRN INLAND EMPIRE THIS AM. STRATUS REMAINS
EXTENSIVE OFFSHORE...OTHERWISE CLEAR. THE 12Z NKX SOUNDING HAD A
STRONG INVERSION BASED NEAR 1600 FT WITH DRY WLY WINDS ALOFT. A GULF
SURGE CAUSED HIGHER DEW POINTS IN THE SRN DESERTS AGAIN THIS AM AND
CU FORMED OVER THE MOUNTAINS THIS AFTERNOON. WEAKENING ONSHORE
GRADIENTS WITH ABOUT 4 MB SAN-IPL.

COULD BE AN ISOLATED HIGH-BASED THUNDERSTORM OVER THE SAN OR RIV
MOUNTAINS THIS AFTERNOON. HOWEVER...LITTLE OR NO PRECIP EXPECTED. THE
UPPER HI BUILDS THROUGH SUN AND THEN WEAKENS A LITTLE MON AND MORE
SO ON TUE AS A TROUGH DEVELOPS TO THE N. THE MARINE LAYER SHOULD
DECREASE JUST SLIGHTLY TONIGHT AND THEN INCREASE A LITTLE BY MON NIGHT
WITH A POSSIBLE WEAK EDDY. THE INVERSION WILL REMAIN STRONG AND WILL
LIKELY RESULT IN SLOW CLEARING AT SOME BEACHES. WARMER SUN AND THEN
NOT MUCH TEMP CHANGE MON WITH HOT DAYS INLAND. COOLER IN MOST AREAS
TUE. THE THERMAL LOW IN THE DESERTS WILL INCREASE DURING THE
AFTERNOONS AND EVENINGS FOR THE USUAL LOCALLY BREEZY CONDITIONS IN THE
MOUNTAINS AND DESERTS. THERE WILL BE SOME INCREASE IN MID LEVEL
MOISTURE SUN AND MON BUT IT REMAINS RATHER LIMITED FOR JUST A VERY
SMALL CHANCE OF THUNDERSTORMS IN THE HIGHER MOUNTAINS DURING THE
AFTERNOONS...MAINLY S.

.LONG TERM...WEAK TROUGHING ALOFT WILL BRING COOLER WEATHER AND A
DEEPER MARINE LAYER DURING THE SECOND HALF OF NEXT WEEK. THE UPPER
HIGH SHOULD REBUILD OVER THE SW EARLY NEXT WEEK FOR WARMING AND A
RETURN OF MONSOONAL MOISTURE.

.SGX WATCHES/WARNINGS/ADVISORIES...NONE.
