AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
830 AM PDT MON APR 13 2015

.SYNOPSIS...

A TROUGH OF LOW PRESSURE MOVING TOWARD THE WEST COAST TODAY AND INTO
THE GREAT BASIN ON TUESDAY WILL BRING INCREASING WESTERLY WINDS
ACROSS THE MOUNTAINS AND DESERTS. THIS WILL ALSO DEEPEN THE MARINE
LAYER AND BRING MODEST COOLING ACROSS THE REGION. THE TROUGH WILL
DEVELOP INTO A SLOW-MOVING LOW PRESSURE AREA AS IT DROPS FARTHER
SOUTH INTO NEW MEXICO BY FRIDAY...TURNING OUR WINDS OFFSHORE
WEDNESDAY...AND SCOURING OUT THE MARINE LAYER. THIS WILL KEEP THE
DESERTS COOLER...BUT BRING WARMING WEST OF THE MOUNTAINS WITH GUSTY
NORTHEAST WINDS ALONG THE FOOTHILLS. GRADUAL COOLING WEST OF THE
MOUNTAINS AND WARMER OVER THE DESERTS THIS WEEKEND AS WEAK ONSHORE
FLOW RETURNS.

&&

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

POSSIBLE STRONG OFFSHORE WIND GUSTS BELOW THE SAN BERNARDINO AND
SANTA ANA MTS WEDNESDAY AND THURSDAY....

THE MARINE STRATUS WAS MUCH MORE EXTENSIVE THIS MORNING ALONG THE
COASTAL STRIP AND OVER THE COASTAL WATERS. ONE OF THE REASONS WAS
LIKELY THE STRONGER 8 DEGREE C INVERSION INDICATED ON THE 12Z
MIRAMAR SOUNDING BASED NEAR 1100 FT. WINDS WERE GENERALLY LIGHT...
WITH NEUTRAL SFC PRESSURE GRADIENTS FROM SAN TO NV AND 4 MBS ONSHORE
TO THE LOWER DESERTS AT 8 AM PDT.

THE MARINE CLOUDS WILL CLEAR THIS MORNING LEAVING FAIR SKIES. IT
WILL BE SLIGHTLY WARMER AS WELL UNDER A WEAK HIGH PRESSURE RIDGE.
THE MARINE CLOUDS AND LOCAL FOG WILL RETURN OVERNIGHT AND SPREAD
FARTHER INTO THE VALLEYS. SLIGHTLY COOLER ON TUESDAY.

A LOW PRESSURE TROUGH IS APPROACHING THE NOCAL COAST TODAY..AND WILL
SWING INLAND OVER NV ON TUE. THE TROUGH WILL LOWER SFC PRESSURE OVER
THE GREAT BASIN AND RESULT IN INCREASING WESTERLY WINDS ACROSS CA.
THE WINDS WILL BECOME GUSTY OVER NORTHERN PORTIONS OF THE CWA THIS
AFTERNOON...THEN SPREAD SOUTH ACROSS THE MTS/DESERTS THIS EVENING
THROUGH TUE. THE WINDS MAY APPROACH ADVISORY STRENGTH IN A FEW WIND
PRONE AREAS THIS EVENING AND AGAIN LATE TUE BEFORE TURNING NORTHERLY
TUE NIGHT/WED.

THERE REMAINS CONSIDERABLE UNCERTAINTY WITH THE FUTURE DEVELOPMENT
OF THE TROUGH AS IT DIGS SOUTH LATER IN THE WEEK...BUT THE SLOWER
SOLUTION ADVERTISED BY THE ECMWF MODEL IS FAVORED. THIS SCENARIO
WOULD KEEP THE STRONGER OFFSHORE WINDS MAINLY NORTH OF SAN DIEGO
COUNTY...WITH THE BETTER SFC AND UPPER-LEVEL SUPPORT. LATEST
GUIDANCE SUGGESTS A HIGH WIND POTENTIAL BELOW THE CAJON AND MORONGO
PASSES WED/THU MORNINGS. HOPEFULLY THE 12Z MODEL RUNS WILL BUILD
CONFIDENCE IN THE WIND POTENTIAL. IN ANY CASE...THE OFFSHORE WILL
MEAN SUNNY AND WARMER DAYS WEST OF THE MTS WITH VERY LOW RH.

AS THE LOW DRIFTS EAST OVER THE WEEKEND...A WEAKNESS IN THE HEIGHT
FIELD LINGERS ALONG THE WEST COAST...EVENTUALLY DEVELOPING INTO
ANOTHER AREA OF LOW PRESSURE. THE LATEST EC/GFS MODEL SOLUTIONS ARE
ACTUALLY CLOSER WITH THIS DEVELOPING WEAK SYSTEM THAN WITH THE
DEVELOPING CUT-OFF DURING THE MIDDLE OF THE WEEK. SO LOOK FOR SOME
COOLING W OF THE MTS AND WARMING OVER THE DESERTS THIS
UPCOMING WEEKEND.

STILL NO RAIN IN SIGHT AND SKIES WILL BE FAIR EXCEPT FOR PERIODS OF
NIGHT AND MORNING MARINE CLOUDS AND LOCAL FOG.

&&

.AVIATION... 131515Z...COAST/VALLEYS...SCT/BKN LOW CLOUDS WITH BASES
1100-1500 FT MSL AND TOPS 2000 FT MSL WILL ERODE TO THE COAST
BETWEEN 13/1600Z-1700Z. MOSTLY CLEAR CONDITIONS THIS AFTERNOON WITH
LOW CLOUDS...SLIGHTLY DEEPER THAN THIS MORNING PUSHING INLAND 10 TO
15 SM AFT 14/0700Z TONIGHT. KONT MAY BE AFFECTED BY THIS STRATUS
LAYER BETWEEN 14/0900Z-1200Z. VIS GENERALLY P6SM...THOUGH COULD
LOWER TO 3-5SM WHERE THE CLOUDS INTERSECT TERRAIN ON THE COASTAL
SLOPES.

MTS/DESERTS...TYPICAL LIGHT DIURNAL WINDS WITH SKC CONDS.
