SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
450 PM PDT SUN JUL 19 2015

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...

MOISTURE FROM TROPICAL STORM DOLORES WILL BRING WARM AND HUMID
CONDITIONS TO THE AREA THROUGH MONDAY...ALONG WITH PLENTY OF CLOUDS
AND SCATTERED THUNDERSTORMS AT TIMES. LESS HUMID CONDITIONS WILL
RETURN BY MID WEEK AS THE TROPICAL AIRMASS MOVES EAST...WITH
TEMPERATURES NEAR SEASONAL NORMS THROUGH THE END OF THE WEEK.

&&

.SHORT TERM (TODAY-WED)...THERE CONTINUED TO BE SHOWERS AND
THUNDERSTORMS ACROSS SLO COUNTY THIS AFTERNOON. DOPPLER RADAR STORM
ESTIMATES HAVE SHOWN OVER 2.5 INCHES OF RAIN OVER PORTIONS OF SLO
COUNTY TODAY. AS FAR AS AREAS TO THE SOUTH...THUNDERSTORMS HAVE
DEVELOPED AS EXPECTED ACROSS THE LA/VTU/SBA COUNTY MTNS THIS
AFTERNOON. STORMS WERE MOVING BETWEEN 10 AND 20 MPH TO THE NORTH-
NORTHWEST FOR THE MOST PART. PRECIPITABLE WATERS ARE BETWEEN 1.75
AND 2 INCHES. THEREFORE...ANY THUNDERSTORM THAT DEVELOPS WILL BE
CAPABLE OF DUMPING HEAVY RAIN OVER THAT AREA. THE STEERING WINDS
WHICH ARE FROM THE SOUTH ARE NOT TOO FAST...THEREFORE FLASH FLOODING
WILL BE A THREAT TODAY...AND CONTINUE THROUGH MONDAY EVE. A FLASH
FLOOD WATCH REMAINS IN EFFECT FOR THE MOUNTAINS OF LOS
ANGELES...VENTURA AND SANTA BARBARA COUNTIES. ALSO...THE COLBY AND
SPRINGS BURN AREAS ARE INCLUDED IN THE FLASH FLOOD WATCH.

SYNOPTICALLY...POST-TROPICAL STORM DOLORES WAS 350 MILES SSW OF LOS
ANGELES. THE MAIN CORE OF DOLORES WILL CONTINUE TO MOVE NORTH THEN
TURN SLIGHTLY TO THE NE AS IT REACHES THE SOCAL BIGHT LATER THIS
EVENING OR TONIGHT. THERE WILL BE PLENTY OF CLOUDS AND SCATTERED
SHOWERS OVER LA/VTU COUNTIES INITIALLY THIS EVENING...THEN SPREAD
NORTHWARD INTO SANTA BARBARA AND SAN LUIS OBISPO COUNTIES OVERNIGHT.

TODAY'S HIGH TEMPS OVER THE LA/VTU COAST AND VALLEYS WERE HIGHER
THAN YESTERDAY DUE TO MORE SUNSHINE...AND A WEAK OFFSHORE GRADIENT
THANKS TO DOLORES. DOWNTOWN LOS ANGELES HAS REACHED 90 DEGREES
TODAY...WHILE OTHER COASTAL CITIES LIKE SANTA BARBARA HAVE REACHED
86 SO FAR.

FOR MONDAY...THERE WILL CONTINUE TO BE ENOUGH LINGERING MID LEVEL
MOISTURE OVER SOUTHERN CALIFORNIA AND SOME MORNING CLEARING TO HELP
DESTABILIZE THE ATMOSPHERE ONCE AGAIN...WHILE AREAS N OF POINT
CONCEPTION SHOULD REMAIN MOSTLY CLOUDY MUCH OF THE DAY WITH PERIODS
OF RAIN WITH EMBEDDED THUNDERSTORMS. HIGH TEMPS SHOULD BE A BIT
COOLER TOMORROW WITH MORE CLOUD COVERAGE EXPECTED OVER THE METRO
AREAS. AS HAS BEEN THE CASE...IT IS DIFFICULT TO PIN-POINT WHERE AND
WHEN SHOWERS WILL DEVELOP. BEST CHANCES WILL BE IN THE AFTERNOON AND
EVENINGS ACROSS THE MOUNTAINS AND DESERT AREAS. BY MONDAY
NIGHT...THE REMNANTS OF DOLORES WILL HAVE MOVED INTO THE NORTHERN
PART OF CALIFORNIA THEN MOVE INTO NEVADA. THERE WILL CONTINUE TO BE
SOME LINGERING MOISTURE FOR AREAS N OF LOS ANGELES COUNTY ON
TUESDAY. HAVE TAKEN OUT POPS FOR THE LA COUNTY MTNS BUT HAVE LEFT
THEM FOR VTU/SBA COUNTY MTNS AS THERE WILL BE ENOUGH INSTABILITY TO
JUSTIFY A SLIGHT CHANCE FOR THUNDERSTORMS. MODEL SOUNDING OVER MT.
BALDY LOOKED PRETTY DRY...THEREFORE TOOK OUT TUE AFTERNOON POPS FOR
L.A. COUNTY MTNS. THERE WILL CONTINUE TO BE A BROAD UPPER TROUGH
OVER CALIFORNIA WHICH WILL HELP TO STRENGTHEN THE MORE STABLE
ONSHORE FLOW. EXPECT A RETURN OF NIGHT THROUGH MORNING LOW CLOUDS AT
LEAST BY TUESDAY NIGHT INTO WED MORNING WITH COOLER TEMPS EXPECTED
AT COASTAL AREAS...BUT SOME WARMING INLAND DUE TO LESS CLOUD COVER.

THE UPPER TROUGH DEEPENS FURTHER ON WEDNESDAY...WHICH SHOULD HELP
STRENGTHEN THE ONSHORE GRADIENT ALLOWING FOR COOLER TEMPS ALONG THE
COAST...AND A RETURN OF NIGHT THROUGH MORNING LOW CLOUDS FOR BUT
HIGHS INLAND WILL REMAIN IN THE MID 80S TO AROUND 90 IN WARMEST
LOCATIONS. THE WEATHER PATTERN WILL BE BACK TO A MORE NORMAL REGIME
BY WEDNESDAY. THERE WILL BE A FEW FLAT CU BUILDUPS IN THE
SLO/SBA/VTU COUNTY MTNS.

.LONG TERM (THU-SUN)...A BROAD UPPER TROUGH WILL PERSIST OVER THE
REGION THROUGH FRIDAY. AFTER THE UPPER TROUGH PUSHES EAST...AN
ELONGATED UPPER RIDGE FROM TEXAS AND AZ WILL NUDGE FARTHER WEST
UNDERCUTTING THE TROUGH. THIS WILL CAUSE TEMPS TO INCREASE AS
HEIGHTS AND THICKNESS LVLS WILL INCREASE. THE ONSHORE FLOW WILL NOT
BE AS STRONG AS WELL. EXPECT NEAR NORMAL TEMPS THU...WITH HIGHER
THAN NORMAL TEMPS INLAND FOR THE REMAINDER OF THE WEEK. THERE WILL
CONTINUE TO BE NIGHT THROUGH MORNING LOW CLOUDS ACROSS COAST AND
POSSIBLY COASTAL VALLEYS.
