AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
ISSUED BY NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
915 AM PDT MON SEP 14 2015

.SYNOPSIS...
MOISTURE FROM THE REMNANTS OF FORMER HURRICANE LINDA AND UPSLOPE
FLOW WILL HELP CREATE PERIODS OF RAIN OVER MOST OF THE REGION
ALONG AND WEST OF THE MOUNTAINS INTO WEDNESDAY...WITH THE
GREATEST COVERAGE OF SHOWERS TONIGHT THROUGH TUESDAY EVENING ALONG
AND WEST OF THE MOUNTAINS WITH GREATEST RAINFALL AMOUNTS ON THE
COASTAL MOUNTAIN SLOPES. DRYING AND A WARMING TREND WILL FOLLOW
INTO NEXT WEEKEND.

&&

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

.SHORT TERM (TODAY THROUGH WEDNESDAY)...
SEE NO REASON FOR CHANGES TO THE CURRENT FORECAST. THE COMBINATION
OF INCREASED TROUGHING ON THE WEST COAST AND REMNANTS OF EX-
HURRICANE LINDA MOISTURE WILL CONTINUE TO INCREASE THE CLOUDS AND
BRING A SLIGHT CHANCE OF SHOWERS...MAINLY TO AREAS WEST OF THE
MOUNTAINS TODAY. THERE IS A GREATER CHANCE OF SHOWERS TONIGHT AND
TUESDAY WEST OF THE MOUNTAINS WITH A SLIGHT CHANCE OF SHOWERS
EXTENDING INTO THE DESERT SECTIONS. THE BEST CHANCE OF SHOWERS
AND HIGHEST AMOUNTS WILL BE ON THE COASTAL SLOPES OF THE MOUNTAINS.

SURFACE PRESSURE GRADIENTS ARE TRENDING ONSHORE AND ALONG WITH LOWER
HEIGHTS THE AREA WILL SEE COOLER HIGH TEMPERATURES TODAY AND
TUESDAY. THE STRONGER ONSHORE FLOW WILL ALSO RESULT IN GUSTY
AFTERNOON WINDS ESPECIALLY IN THE MOUNTAIN AND DESERT LOCATIONS.

...FROM PREVIOUS DISCUSSION...

A SECOND SHORTWAVE FROM THE NORTHWEST COULD INCREASE THE COVERAGE
AND AMOUNTS OF THE RAINFALL SOMEWHAT FOR TUESDAY INTO TUESDAY
EVENING WITH GREATEST RAINFALL AMOUNTS REMAINING ON THE COASTAL
MOUNTAIN SLOPES.

AS THE DEPTH OF THE SATURATED LAYER GRADUALLY DECREASES TUESDAY
NIGHT INTO WEDNESDAY...RAINFALL COVERAGE AND AMOUNTS ARE EXPECTED
TO GRADUALLY DECREASE. A FEW LIGHT SHOWERS COULD LINGER NEAR THE
MOUNTAINS INTO WEDNESDAY AFTERNOON.

RAINFALL AMOUNTS THROUGH WEDNESDAY ARE EXPECTED TO RANGE FROM
AROUND ONE HALF INCH NEAR THE COAST TO 1 TO 2 INCHES ON THE
COASTAL MOUNTAIN SLOPES WITH ONE QUARTER INCH OR LESS IN THE UPPER
DESERTS.

WITH CLOUD COVER AND STRONGER ONSHORE FLOW...HIGH TEMPERATURES ARE
EXPECTED TO COOL INTO WEDNESDAY FOR INLAND AREAS. WITH SEA SURFACE
TEMPERATURES IN THE UPPER 70S NEAR THE SAN DIEGO COUNTY
COAST...LOW TEMPERATURES NEAR THE COAST ARE EXPECTED TO REMAIN
ABOVE AVERAGE.

THE STRONGER ONSHORE FLOW WILL BRING GUSTY WEST WINDS IN THE
MOUNTAINS AND DESERTS INTO WEDNESDAY.

&&

.LONG TERM (THURSDAY THROUGH SUNDAY)...
THE TROUGH OF LOW PRESSURE NEAR THE WEST COAST WILL WEAKEN THROUGH
THE WEEKEND WITH A SLOW INLAND WARMING TREND FOR THURSDAY THROUGH
SUNDAY. DRY WEATHER IS EXPECTED WITH AREAS OF NIGHT AND MORNING
LOW CLOUDS AND PATCHY FOG FOR COASTAL AREAS.

&&

.AVIATION...

140900Z...AREAS OF LOW CLOUDS WITH BASES 1500-2000 FEET MSL AND TOPS
2500-3000 FEET WILL GRADUALLY INCREASE DURING THE MORNING. TIMING
FOR EXACT COVERAGE ON COASTAL AIRPORTS IS VERY UNCERTAIN. LOW CLOUDS
WILL SPREAD INTO THE INLAND VALLEYS THROUGH THE DAY...WITH BASES
LIFTING TO AROUND 3000 FEET MSL AND TOPS RISING TO AROUND 6000 FEET.
THERE IS ALSO AN INCREASING CHANCE OF SHOWERS COINCIDING WITH THE
INCREASE IN CLOUDS. SOME OF THE COASTAL SLOPES OF THE MOUNTAINS WILL
BE OBSCURED AT TIMES DURING THE AFTERNOON THROUGH THE NIGHT. IN THE
HIGHER MOUNTAINS AND DESERTS...MOSTLY CLEAR SKIES WILL PREVAIL
TODAY...WITH INCREASING CLOUDS AOA 10000 FEET MSL TONIGHT.
