AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO 130 PM PDT MON AUG 9 2004 .SYNOPSIS...A SHALLOW MARINE LAYER AND ONSHORE FLOW WILL CONTINUE AREAS OF COASTAL LOW CLOUDS AND FOG IN THE NIGHTS AND MORNINGS. INCREASING MOISTURE IN SOUTHEAST FLOW ALOFT WILL BRING A SLIGHT CHANCE OF AFTERNOON THUNDERSTORMS TO THE MOUNTAINS AND DESERTS DURING THE WEEK. OTHERWISE...HIGH PRESSURE ALOFT WILL MAINTAIN FAIR AND SEASONABLY HOT WEATHER. THE HIGH WILL WEAKEN LATE IN THE WEEK BRINGING COOLER WEATHER BY THE WEEKEND. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES. .SHORT TERM...VISIBLE SATELLITE LOOPS THIS MORNING SHOW A CONSIDERABLE AMOUNT OF CLOUD COVER ADVECTING WESTWARD OVER NW MEXICO. SOME OF THIS IS MOVING OVER IMPERIAL COUNTY AND HAS PROVIDED ADDITIONAL RH TO THE SAN DIEGO COUNTY MTNS FOR CU AND ISOLATED SHOWERS AND THUNDERSTORMS. MOST ACTIVITY IS LIKELY TO AGAIN BE S OF THE BORDER THIS AFTERNOON. WEAK ONSHORE SURFACE PRESSURE GRADIENTS AND TEMPS RUNNING GENERALLY 2 TO 4 DEGREES WARMER THAN YESTERDAY. HOT TEMPS AROUND THE CENTURY MARK ALREADY IN THE SAN DIEGO COUNTY FOOTHILLS. LOW CLOUDS HANGING JUST OFF THE COAST HAVE BEEN SLOWER TO CLEAR UNDER THE STRONGER INVERSION. ETA MODEL THIS MORNING ACTUALLY INITIALIZED THE STRONG UPPER HIGH NEAR THE FAVORABLE FOUR CORNERS AREA. THIS POSITION DID OPEN THE DOOR FOR MOISTURE TO BEGIN TO STREAM TOWARD SOCAL FROM S AZ. HOWEVER...THE MODEL BUILDS THE HIGH SW THROUGH TUE MORNING TO A POSITION OVER THE LOWER CO RIVER VALLEY. THIS WOULD CHOKE OFF THE MOISTURE FLOW FROM THE SE LATER TODAY. MODEL CROSS SECTIONS STILL HINT AT ENOUGH MOISTURE MAKING IT IN HERE FOR SLIGHT CHANCE... ESPECIALLY SAN DIEGO COUNTY MTNS TUE...INCREASING ALL AREAS ON WED AS THE HIGH CENTER WAFFLES BACK E OVER AZ. EVEN THOUGH IT IS NOT THE MOST FAVORABLE SCENARIO FOR MONSOON ACTIVITY...CURRENT SATELLITE DATA SUGGESTS WE NEED A SLIGHT CHANCE TUE PM. ELSEWHERE...TOMORROW WILL PROBABLY BE THE HOTTEST DAY...SIMILAR TO TODAY...BEFORE HEIGHTS BEGIN A SLOW AND STEADY FALL FOR GRADUAL COOLING FOR THE REMAINDER OF THE WEEK. AREAS OF NIGHT AND MORNING LOW CLOUDS AND FOG WILL CONTINUE NEAR THE COAST...WITH LOCAL DENSE FOG POSSIBLE...PENETRATING FARTHER INLAND AS THE HIGH WEAKENS AND DROPS S INTO MEXICO BY MIDWEEK. .LONG TERM...THE GFS HAS BEEN CONSISTENT WITH WEAKENING THE UPPER HIGH OVER THE SW U.S. LATER THIS WEEK. AS IT SLIPS WELL S OF THE BORDER OUR UPPER LEVEL FLOW BECOMES INCREASINGLY SW. INITIALLY THIS BRINGS IN A CONSIDERABLE AMOUNT OF HIGH LEVEL MOISTURE WITH SURVIVED THE TRIP AROUND THE HIGH FROM THE GULF OF MEXICO. THIS COULD RESULT IN MORE WIDESPREAD SHOWERS AND CLOUDS...OR JUST CLOUDS IF WE DO NOT GET ENOUGH HEATING/INSTABILITY. IN ANY CASE THERE WILL BE A THREAT OF SHOWERS INTO FRI...BEFORE THE W FLOW DRIES US OUT FOR THE WEEKEND. MUCH COOLER AND DRY FOR THE WEEKEND INTO NEXT WEEK WITH A BROAD TROUGH IN PLACE ACROSS SW. .SGX WATCHES/WARNINGS/ADVISORIES...NONE. && JAD
