COOLER TOWARD THE END OF THE WEEK AS THE HIGH WEAKENS. A REDEVELOPING MARINE LAYER WILL CAUSE COASTAL LOW CLOUDS AND FOG DURING THE NIGHTS AND MORNINGS. INCREASING MID LEVEL MOISTURE WILL CAUSE AFTERNOON CLOUDS OVER THE MOUNTAINS AND DESERTS...WITH A CHANCE FOR THUNDERSTORMS BY TUESDAY. && .DISCUSSION...FOR SOUTHWEST CALIFORNIA INCLUDING SAN DIEGO... ORANGE...SOUTHWEST SAN BERNARDINO AND WEST RIVERSIDE COUNTIES. .SHORT TERM (TODAY-TUESDAY)...SKIES WERE MOSTLY CLEAR EARLY THIS MORNING EXCEPT FOR A FEW HIGH CLOUDS AND SOME PATCHY FOG SOUTH OF IMPERIAL BEACH. THE 12Z KNKX SOUNDING INDICATED A SURFACE BASED RADIATIONAL INVERSION WITH VERY WARM AIR ALOFT. THE TEMPERATURE AT THE TOP OF THE INVERSION AT 1800 FT WAS A WHOPPING 90F...SO ANOTHER HOT DAY IS ON TAP. ONSHORE GRADIENTS WITH ABOUT 3 MB SAN-IPL. STRONG HIGH PRESSURE ALOFT WILL BEGIN TO SHIFT EAST IN RESPONSE TO A TROUGH MOVING PAST TO THE NORTH. THIS WILL INITIATE A COOLING TREND. CURRENT TEMPERATURES ARE RUNNING SLIGHTLY COOLER THAN 24 HOURS AGO...HOWEVER MAX TEMPS WILL STILL BE WELL ABOVE SEASONAL AVERAGES. IT WILL BE VERY DRY TOO WITH MIN RELATIVE HUMIDITIES IN THE SINGLE DIGITS AND LOW TEENS...SO THE HEAT INDEX WILL BE SEVERAL DEGREES LOWER THAN THE ACTUAL TEMPERATURE. THE HOT AND DRY WEATHER WILL MAINTAIN AN ELEVATED FIRE WEATHER THREAT...HOWEVER DO NOT EXPECT WIDESPREAD RED FLAG CRITERIA TO BE MET. PATCHY MARINE STRATUS SHOULD RETURN TONIGHT AND BRING COASTAL LOW CLOUDS AND FOG DURING THE NIGHTS AND MORNINGS. THE MARINE LAYER WILL START OUT QUITE SHALLOW AND THERE COULD BE DENSE FOG IN THE COASTAL AREAS LATE TONIGHT AND MONDAY MORNING. STRONG THERMALS OVER THE MOUNTAINS WILL CAUSE SOME AFTERNOON CU TODAY AND MONDAY. MID LEVEL MOISTURE IS EXPECTED TO INCREASE TUESDAY AS A WEAK INVERTED TROUGH APPROACHES FROM THE SOUTHEAST. THIS WILL BRING A SLIGHT CHANCE OF THUNDERSTORMS TO THE MOUNTAINS AND DESERTS. MID LEVEL FLOW IN EXCESS OF 15 KT IN COMBINATION WITH MID AND HIGH CLOUDS COULD LIMIT THE CHANCE FOR THUNDERSTORMS...BUT GIVEN THE UNCERTAINTY THAT EXISTS IN THE DETAILS...FELT SLIGHT CHANCE WAS WARRANTED. THE INCREASE IN MOISTURE AND CLOUDS SHOULD KNOCK THE TEMPERATURES DOWN SEVERAL DEGREES...BUT STILL SLIGHTLY WARMER THAN SEASONAL AVERAGES. && .LONG TERM (WEDNESDAY-SATURDAY)...MINOR CHANGES WEDNESDAY WITH SLIGHT COOLING THURSDAY. THERE WILL BE SOME AFTERNOON CU OVER THE MOUNTAINS. THERE MAY ALSO BE ENOUGH INSTABILITY FOR A SLIGHT CHANCE OF THUNDERSTORMS.
