NATIONAL WEATHER SERVICE SAN DIEGO CA
133 PM PDT THU SEP 18 2014
.SYNOPSIS...
A LOW PRESSURE TROUGH MOVING SLOWLY MOVING THROUGH CENTRAL 
CALIFORNIA WILL BRING COOLER WEATHER AND NIGHT AND MORNING STRATUS 
INTO THE COAST AND VALLEYS SECTIONS THROUGH SUNDAY. STRONGER ONSHORE 
FLOW FROM THIS TROUGH WILL BRING GUSTY WEST WINDS TO THE MOUNTAINS 
AND DESERTS THROUGH EARLY FRIDAY MORNING. THE MARINE LAYER MAY BE 
THICK ENOUGH TO BRING PATCHY DRIZZLE OVERNIGHT TONIGHT. ISOLATED 
THUNDERSTORMS MAY FORM OVER THE MOUNTAINS SATURDAY AFTERNOON DUE TO 
A POSSIBLE INCREASE IN MOISTURE FROM THE SOUTH. A WARMING TREND AND 
SHALLOWER MARINE LAYER IS EXPECTED FOR THE FIRST HALF OF NEXT WEEK 
AS HIGH PRESSURE ALOFT EXPANDS INTO THE REGION.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
PATCHY STRATUS HAS CLEARED OUT OF THE COAST AND VALLEY SECTIONS THIS 
MORNING...WITH NO CUMULUS OVER THE MOUNTAINS...ACCORDING TO VISIBLE 
SATELLITE. THE 12Z MIRAMAR SOUNDING SHOWED A 5 DEGREE MARINE 
INVERSION AT AROUND 1600 FEET...WITH LESS INSTABILITY THAN THE PAST 
FEW DAYS...WESTERLY FLOW THROUGH THE PROFILE...AND A STRONG CAPPING 
INVERSION AT AROUND 620 MB. SPC MESOANALYSIS ALSO SHOWS NO 
INSTABILITY OVER OUR AREA...AND GPS MET PRECIPITABLE WATER SENSORS 
INDICATE VALUES OF ONLY 1 INCH IN THE DESERTS...AND 0.8 INCH OR LESS 
WEST OF THE MOUNTAINS. THUS...WITH THE DRIER AIR AND INCREASING 
STABILITY...THERE SHOULD NOT BE ANY THUNDERSTORMS/SHOWERS DEVELOPING 
OVER THE MOUNTAINS AND DESERTS TODAY. WITH THE DRY AIR...AND ONSHORE 
FLOW...CONDITIONS HAVE COOLED SIGNIFICANTLY IN ALL AREAS EXCEPT FOR 
THE DESERTS...WITH TEMPERATURES 8-15 DEGREES LOWER THAN THEY WERE 24 
HOURS AGO. HOWEVER...A TROUGH JUST OFF THE COAST OF NORTH-CENTRAL 
CALIFORNIA WILL CONTINUE TO DRIFT SOUTH THROUGH TONIGHT...BRINGING 
STRENGTHENING OF ONSHORE FLOW AND A DEEPER MARINE LAYER FOR TONIGHT 
INTO TOMORROW...WITH STRATUS MOVING DEEP INTO THE INLAND VALLEYS. 
THERE ARE STILL INDICATIONS THAT THE MARINE LAYER MAY BE THICK 
ENOUGH FOR SOME PATCHY DRIZZLE TO FORM WEST OF THE MOUNTAINS ALSO. 
THE ONSHORE PRESSURE GRADIENTS HAVE STRENGTHENED SIGNIFICANTLY 
TODAY...AS THE SAN DIEGO TO THERMAL GRADIENT IS CURRENTLY 7.8 MB 
ONSHORE...WHEREAS IT WAS ONLY 1.8 MB ONSHORE 24 HOURS AGO. THIS IS 
RESULTING IN STRONG AND GUSTY WEST WINDS AT THE MOUNTAIN 
RIDGES...DESERT SLOPES AND ADJACENT DESERTS. WHITEWATER RAWS 
REPORTED A 53 MPH GUST AT 1150 AM. DUE TO THE STRONG WINDS...A WIND 
ADVISORY HAS BEEN ISSUED FOR THE COACHELLA VALLEY AND CONTINUES 
THROUGH EARLY FRIDAY MORNING. WINDS WILL LIKELY NOT BE QUITE AS 
STRONG IN THE SAN DIEGO DESERTS. 
COOLING WILL CONTINUE ON FRIDAY AS A CLOSED LOW SPLITS OUT OF THE 
TROUGH AND ASSUMES A POSITION NEAR POINT CONCEPTION...WITH MOST 
PLACES EXPECTED TO BE SEVERAL DEGREES BELOW NORMAL FOR DAY-TIME HIGH 
TEMPERATURES. THE LOW WILL THEN SLOWLY MOVE NORTHEAST INLAND THROUGH 
CENTRAL CALIFORNIA AND NEVADA LATE SATURDAY INTO SUNDAY. 
TEMPERATURES FOR SATURDAY AND SUNDAY MAY BE SLIGHTLY WARMER AS 850 
MB TEMPERATURES INCREASE SLIGHTLY. THERES A CHANCE THAT THE LOW 
COULD BRING UP ENOUGH MOISTURE FROM THE SOUTH TO BRING SOME 
THUNDERSTORMS TO THE MOUNTAINS AND DESERTS SATURDAY AFTERNOON. ITS A 
PRETTY SLIM CHANCE THOUGH...AS MODELS SHOW THE BULK OF THE MOISTURE 
STAYING TO THE EAST OF OUR AREA. THE MARINE LAYER LOOKS TO REMAIN 
DEEP...WITH NIGHT AND MORNING STRATUS MOVING INTO THE INLAND 
VALLEYS. 
FOR MONDAY THROUGH WEDNESDAY...AN UPPER LEVEL RIDGE TO THE SOUTH 
WILL EXPAND INTO THE REGION...BRINGING A WARMING TREND...WITH THE 
MARINE LAYER BECOMING INCREASINGLY SHALLOW...WITH NIGHT AND MORNING 
STRATUS/FOG MAINLY ALONG THE COAST. 
&&
.AVIATION...
182030Z...COAST/VALLEYS...BKN-SCT CLOUDS BASED 1500-2000 FEET 
MSL...TOPS 2500 FEET MSL...OVER THE COASTAL WATERS OTHERWISE MOSTLY 
CLEAR WITH UNRESTRICTED VISIBILITIES. AFTER 01Z THIS AFTERNOON OVC 
LOW CLOUDS BASED 1800-2500 FEET MSL...TOPS APPROACHING 3000 FEET 
MSL...WILL MOVE INLAND...REACHING KRNM/KONT AROUND 08Z TONIGHT. LOW 
CLOUDS SHOULD CLEAR SOMEWHAT LATER FRIDAY MORNING COMPARED TO TODAY. 
CONFIDENCE IN THE STRATUS ARRIVAL TIMES AT THE COASTAL TAFS IS 
MODERATE FOR THIS EVENING. 
 
MOUNTAINS/DESERTS...WEST WINDS WITH SFC GUSTS 25-35 KT WILL DEVELOP 
OVER THE DESERT MOUNTAIN SLOPES AND ADJACENT DESERT FOOTHILLS THIS 
AFTERNOON AND EVENING. OTHERWISE MOSTLY CLEAR WITH UNRESTRICTED 
VISIBILITIES THROUGH FRI MORNING.
&&
