NATIONAL WEATHER SERVICE SAN DIEGO CA
114 PM PDT MON OCT 20 2014
.SYNOPSIS...
PLEASANT FALL WEATHER WILL PREVAIL ACROSS THE SOUTHLAND THROUGH 
TUESDAY AS A LOW PRESSURE TROUGH ALOFT TRACKS INLAND. THE ONSHORE 
FLOW WILL BECOME LOCALLY GUSTY IN THE MOUNTAINS AND DESERT PASSES... 
AND WILL MAINTAIN THE MARINE LAYER AND ASSOCIATED CLOUDS WEST OF THE 
MOUNTAINS. BY WEDNESDAY...THE MARINE LAYER WILL BE SHRINKING BACK TO 
THE COAST AS HIGH PRESSURE BUILDS ALOFT AND THE SURFACE FLOW 
WEAKENS. IT WILL BE MUCH WARMER ON THURSDAY AND FRIDAY...BUT THE 
NIGHTS WILL BE COOL UNDER CLEAR SKIES AND LIGHT WINDS. ONSHORE FLOW 
WILL RETURN AGAIN NEXT WEEKEND AS ANOTHER TROUGH SWINGS ACROSS THE 
WEST WITH COOLER DAYS AND A RETURN OF MARINE CLOUDS AND LOCAL FOG.  
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
MARINE STRATUS WAS STUBBORN TO CLEAR THE COAST AND WESTERN VALLEY 
AREAS THIS MORNING. BY 1 PM THERE WAS STILL SOME ALONG THE IMMEDIATE 
COAST AND A FEW MORE CUMULUS HAD POPPED OVER THE HIGHER MTN CRESTS. 
SKIES WERE CLEAR OVER AND DESERTS. SURFACE PRESSURE GRADIENTS WERE 
WEAK ONSHORE AT MIDDAY AND WINDS WERE LIGHT.    
THE MARINE LAYER CLOUDS WILL SPREAD BACK INLAND AGAIN OVERNIGHT BUT 
ARE EXPECTED TO BURN OFF MORE RAPIDLY ON TUE SUE TO THE ADVECTION OF 
DRIER AND COOLER AIR FROM THE NW. THIS WILL RESULT IN FAIR SKIES AND 
YET ANOTHER FINE AUTUMN DAY ACROSS SOUTHERN CALIFORNIA. WESTERLY 
WINDS WILL BECOME GUSTY THROUGH THE PASSES AND ON THE DESERTS SLOPES 
LATE TODAY...AND CONTINUE INTO TUESDAY...OTHERWISE WINDS WILL BE 
LIGHT. SLIGHTLY COOLER ON TUE AS WELL. 
A VIGOROUS SHORT-WAVE TROUGH IS APPROACHING THE NOCAL COAST THIS 
AFTERNOON AND WILL SWING THROUGH THE STATE TONIGHT. IT WILL MAINTAIN 
ONSHORE FLOW...THE MARINE LAYER... AND AVERAGE DAYTIME TEMPERATURES 
THROUGH TUE. ON WEDNESDAY...HEIGHTS WILL BEGIN TO BUILD ACROSS THE 
SW IN THE WAKE OF THE TROUGH. HIGH PRESSURE WILL BUILD ACROSS THE SW 
AND AMPLIFY NE OVER THE ROCKIES THROUGH FRI. THE ONSHORE FLOW AT THE 
SURFACE WILL WEAKEN...AND MAY EVEN TURN WEAKLY OFFSHORE AS HIGH 
PRESSURE BUILDS INLAND...RESULTING IN MUCH WARMER DAYS....ESPECIALLY 
INLAND. BY SAT...ANOTHER TROUGH WILL APPROACH THE CA COAST AND BEGIN 
TO FLATTEN THE RIDGE. THIS WILL BRING COOLER WEATHER NEXT WEEKEND. 
THE LATEST 12Z GLOBAL MODEL RUNS ARE LOOKING MORE AGGRESSIVE WITH 
THIS FEATURE. IF THAT TREND CONTINUES...A SMALL CHANCE FOR SOME 
MARINE LAYER PRECIP MAY HAVE TO BE INTRODUCED W OF THE MTNS FOR SUN 
MORNING.
DAYTIME TEMPERATURES ARE EXPECTED TO BE 5 TO 10 DEGREES F ABOVE 
AVERAGE THU/FRI...THEN SLIP SAT...AND RETURN TO AVERAGE SUN. 
OVERNIGHT LOWS WILL BE SLIGHTLY ELEVATED IN SOME AREAS...BUT WHERE 
WINDS ARE LIGHT AND SKIES ARE CLEAR INLAND...THERE WILL BE LARGE 
DIURNAL TEMP SWINGS DUE TO THE DRY AIR. MUCH COOLER AS WE MOVE 
THROUGH NEXT WEEKEND.
GIVEN THE WEAK FLOW THAT WILL DEVELOP AFTER TUE...AND THE LINGERING 
HIGH SFC DEWPOINTS ALONG THE COASTAL STRIP UNDER BUILDING HIGH 
PRESSURE ALOFT...AREAS OF DENSE FOG MAY BECOME A CONCERN FOR AREAS 
ALONG AND WEST OF THE MESAS WED THROUGH FRI MORNINGS. 
LOOKING AHEAD TO NEXT WEEK...THERE IS FAIR AGREEMENT BETWEEN MODELS 
THAT THE FLOW ALOFT WILL REMAIN WESTERLY OVER CA...KEEPING 
TEMPERATURES CLOSE TO SEASONAL AVERAGES. UNFORTUNATELY THERE IS 
LITTLE CHANCE FOR ANY PRECIPITATION EITHER. 
&&
.AVIATION...
201930Z...AREAS OF LOW CLOUDS REMAIN OVER THE COASTAL AREAS THIS 
AFTERNOON...WITH BASES AROUND 2000 FT AND TOPS TO 3500 FT. COASTAL 
TAF SITES CONTINUE TO HAVE BKN-OVC CIGS 2000-2500 FT MSL. THESE 
SHOULD BECOME SCT BETWEEN 21Z AND 00Z. LOW CLOUDS LIKELY TO RETURN 
TO COASTAL TAF SITES AFT 00Z TUE...WITH BKN-OVC CIGS AROUND 2000 FT 
MSL AND TOPS TO 3500 FT MSL. CLOUDS WILL SPREAD INLAND BY 12Z TUE 
WITH REDUCED VIS IN AREAS WHERE TERRAIN AND CLOUDS INTERSECT. 
CLEARING TO THE COAST IS EXPECTED BETWEEN 17Z AND 19Z TUE.
&&
.MARINE...
200 PM...NORTHWEST WINDS WILL GUST TO NEAR 20 KT IN THE OUTER 
COASTAL WATERS NEAR SAN CLEMENTE ISLAND THIS EVENING. A NORTHWEST 
SWELL WILL ARRIVE TONIGHT AND TUESDAY...AND WILL COMBINE WITH WIND 
WAVES TO PRODUCE COMBINED SEAS OF 8 TO 10 FEET. THE NORTHWEST SWELL 
WILL DECREASE THROUGH WEDNESDAY.
&&
.BEACHES...
200 PM...A LONG PERIOD NORTHWEST SWELL WILL ARRIVE AT BEACHES 
TONIGHT AND TUESDAY. THIS WILL BRING LARGER SURF MAINLY TO WEST 
FACING BEACHES SOUTH OF DEL MAR. STRONGER RIP CURRENTS WILL ALSO 
DEVELOP...AND THE RIP CURRENT DANGER WILL BE GREATEST LATE TUESDAY 
MORNING DURING THE TRANSITION FROM HIGH TIDE TO LOW TIDE. SEE 
LAXSRFSGX FOR DETAILS.
&&
.FIRE WEATHER...
GUSTY WESTERLY WINDS THROUGH THE PASSES AND LOCALLY INTO THE 
DESERTS...OTHERWISE NO FIRE WEATHER CONCERNS THROUGH TUESDAY. BY 
WEDNESDAY...THE WEATHER WILL TRANSITION TO WARMER AND DRIER INLAND. 
THE DRY AIR WILL TREND FARTHER WEST THROUGH FRIDAY WITH NEUTRAL 
TO WEAK OFFSHORE FLOW PREVAILING. THERE MAY BE SOME LOCALLY GUSTY 
EASTERLY WINDS TO 25 MPH BRIEFLY IN THE MOST WIND PRONE PASS AND 
COASTAL FOOTHILL AREAS...OTHERWISE WINDS WILL BE GENERALLY 15 MPH OR 
LESS THIS PERIOD. INLAND FROM THE COASTAL STRIP...RH WILL DROP TO 
15-20 PERCENT EACH AFTERNOON WEDNESDAY THROUGH FRIDAY. COOLER WITH
