NATIONAL WEATHER SERVICE SAN DIEGO CA
125 PM PDT MON JUN 16 2014
.SYNOPSIS...
A LOW PRESSURE SYSTEM MOVING INLAND THROUGH THE PACIFIC NORTHWEST
AND NORTHERN ROCKIES WILL BRING STRONGER ONSHORE FLOW AND COOLING
THROUGH TUESDAY...SLOW DEEPENING OF THE MARINE LAYER...AND STRONG
AND GUSTY WEST WINDS FOR THE MOUNTAINS AND DESERTS. NIGHT AND
MORNING STRATUS WILL CONTINUE OVER THE COAST AND VALLEY SECTIONS.
GRADUAL WARMING AND A SLIGHTLY SHALLOWER MARINE LAYER FOR WEDNESDAY
INTO NEXT WEEKEND AS HIGH PRESSURE SLOWLY BUILDS OVER THE AREA.
NIGHT AND MORNING STRATUS WILL LIKELY BE CONFINED MAINLY TO THE
COAST AND WESTERN VALLEYS DURING THAT TIME.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
AFTERNOON VISIBLE SATELLITE IMAGERY SHOWED THAT THE PATCHY STRATUS
FROM THIS MORNING HAS CLEARED VERY NICELY. MEANWHILE...WATER VAPOR
SATELLITE INDICATES A LARGE TROUGH OVER THE WEST COAST...WITH A LOW
PRESSURE CENTER OVER WASHINGTON. DUE TO THE DECREASED SUBSIDENCE
PROVIDED BY THE LOWER PRESSURE ALOFT...THE MARINE LAYER WAS ABLE TO
DEEPEN LAST NIGHT TO AROUND 2300-2400 FEET IN SAN DIEGO COUNTY...AND
UP TO 3000 FEET IN ORANGE COUNTY...ACCORDING TO THE 12Z MIRAMAR
SOUNDING AND AIRCRAFT SOUNDINGS. HOWEVER...WITH ONLY A 5 DEG C
INVERSION AND A SOMEWHAT THIN CLOUD LAYER...THE STRATUS CLEARED
PRETTY FAST AFTER SUNRISE. ALSO...THE LOWER PRESSURE ALOFT AND
CONTINUED COOL ONSHORE FLOW ARE BRINGING COOLER CONDITIONS
TODAY...WITH MOST LOCATIONS REPORTING TEMPERATURES THAT ARE A FEW TO
SEVERAL DEGREES LOWER THAN AT THIS TIME YESTERDAY.
STRONG ONSHORE PRESSURE GRADIENTS CONTINUE TODAY...WITH THE SAN
DIEGO TO DAGGETT GRADIENT SHOWING 8.2 MB ONSHORE. STRONG ONSHORE
GRADIENTS WILL CONTINUE THROUGH EARLY WEDNESDAY MORNING AS THE
AFOREMENTIONED TROUGH DEEPENS OVER THE PACIFIC NORTHWEST AND GREAT
BASIN. ALSO...LOCAL WRF CONTINUES TO SHOW 45-50 KT WESTERLY WINDS AT
850 MB AND SOME MOUNTAIN WAVE POTENTIAL. IN ADDITION...THE CANSAC
WRF AND LOCAL WIND GUIDANCE CONTINUES TO SHOW STRONG WINDS IN THE
MOUNTAINS AND DESERTS LATE THIS AFTERNOON THROUGH EARLY TUESDAY
MORNING...AND AGAIN LATE TUESDAY AFTERNOON THROUGH EARLY WEDNESDAY
MORNING. THE WIND ADVISORY FOR THE MOUNTAINS AND DESERTS CONTINUES
THROUGH EARLY WEDNESDAY MORNING...WITH GUSTS OF 50-55 MPH
LIKELY...AND LOCAL GUSTS OF 60 MPH POSSIBLE. THE CONTINUED ONSHORE
FLOW AND INCREASED TROUGHING FOR MONDAY THROUGH TUESDAY WILL ALSO
BRING SLIGHT DEEPENING OF THE MARINE LAYER AND CONTINUED
COOLING...WITH DAY-TIME HIGHS SEVERAL DEGREES BELOW NORMAL. BY
TUESDAY NIGHT/WEDNESDAY MORNING...THE MARINE LAYER MAY DEEPEN TO
3500 FEET...RESULTING IN NIGHT AND MORNING STRATUS DEEP INTO THE
VALLEYS.
500 MB HEIGHTS SHOULD START TO SLOWLY RISE WEDNESDAY THROUGH FRIDAY
AS THE TROUGH MOVES OFF TO THE EAST. THIS SHOULD BRING A WARMING
TREND TO THE AREA...AND LIKELY A GRADUALLY SHALLOWER MARINE LAYER.
EXPECT NIGHT AND MORNING STRATUS TO CONTINUE TO INTRUDE INTO THE
COASTAL AND WESTERN VALLEY AREAS...WITH WEAKER ONSHORE FLOW BRINGING
LIGHTER WESTERLY WINDS OVER THE MOUNTAINS AND DESERTS COMPARED TO
PREVIOUS DAYS.
CONFIDENCE IN THE FORECAST STARTS TO DIMINISH FOR THE WEEKEND...AS
THE 12Z GFS AND 12Z GEM INDICATE GENERALLY ZONAL FLOW ALOFT WITH A
COUPLE WEAK SHORT-WAVE TROUGHS MOVING OVER THE AREA THIS
WEEKEND...WHICH WOULD BRING SOME COOLING AND A DEEPER MARINE LAYER.
MEANWHILE...THE 12Z ECMWF SHOWS A RIDGE TO THE SOUTHWEST EXPANDING
NORTHEAST INTO SOUTHERN CALIFORNIA...BRINGING CONTINUED WARMING AND
A SHALLOWER MARINE LAYER.
