AREA FORECAST DISCUSSION
National Weather Service San Diego CA
205 PM PST THU MAR 10 2016

.SYNOPSIS... A RIDGE OF HIGH PRESSURE WILL CREATE MILD WEATHER
THROUGH THIS EVENING WITH SCATTERED HIGH CLOUDS AND MAXIMUM
TEMPERATURES 5 TO 10 DEGREES ABOVE NORMAL. A QUICK MOVING LOW
PRESSURE TROUGH WILL PUSH THROUGH SOUTHERN CALIFORNIA FRIDAY
AFTERNOON THROUGH EARLY SATURDAY. THIS FEATURE WILL BRING MAINLY
LIGHT TO MODERATE SHOWERS OVER AND WEST OF THE MOUNTAINS...SNOW TO
THE HIGHER TERRAIN...AND A BRIEF PERIOD OF GUSTY WESTERLY WINDS TO
THE MOUNTAIN RIDGE TOPS AND DESERTS. COOLER WEATHER WILL CONTINUE
OVER THE WEEKEND WITH LIGHT RAIN SHOWERS POSSIBLE SUNDAY NIGHT
INTO EARLY TUESDAY. HIGH PRESSURE WILL BRING DRY AND WARMER
WEATHER BY MID NEXT WEEK.

&&

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

AT 2 PM...WATER VAPOR IMAGERY DISPLAYED A DEEP LOW PRESSURE THROUGH
...CENTERED OFF THE COAST OF WASHINGTON STATE...WITH A WELL DEFINED
COLD FRONT EXTENDING SOUTHWARD TOWARDS NORTHERN AND CENTRAL
CALIFORNIA. A PLETHORA OF HIGH CLOUDS WERE OBSERVED STREAMING ACROSS
SOUTHERN CALIFORNIA OUT AHEAD OF THIS FRONT. PRESSURE GRADIENTS HAVE
BEGUN TO TREND WEAKLY ONSHORE...CURRENTLY +1.4 MB FROM SAN-DAG.

TONIGHT...A VERY COMPACT AND QUICK MOVING LOW PRESSURE DISTURBANCE
WILL APPROACH THE SOUTHERN CALIFORNIA COAST. IN RESPONSE...THE
MARINE LAYER WILL DEEPEN AND SURFACE PRESSURE GRADIENTS WILL TREND
STRONGER ONSHORE. THE LOCAL 12Z WRF MODEL DEVELOPS A LOW CLOUD DECK
OVER THE COASTAL WATERS AND PUSHES IT AROUND 10 TO 15 MILES INLAND
BY LATE TONIGHT.

FRIDAY AFTERNOON...AHEAD OF THE AFOREMENTIONED FRONT...GUSTY WEST
WINDS WILL DEVELOP OVER THE MOUNTAINS AND DESERTS AND A WIND
ADVISORY MAY BE WARRANTED. PRECIPITATION CHANCES INCREASE FRIDAY
AFTERNOON INTO THE EVENING AND WILL PERSIST INTO SATURDAY MORNING.
ACCORDING TO THE 12Z WRF AND NAM...CAPE VALUES FRIDAY AFTERNOON AND
EVENING WILL RANGE FROM 150 J/KG - 450 J/KG WEST OF THE MOUNTAINS.
THIS...IN COMBINATION WITH A COMPACT VORT MAX...IS ENOUGH TO JUSTIFY
THE SLIGHT CHANCE OF THUNDERSTORMS CURRENTLY IN THE FORECAST. HAVE
UPPED THE CHANCES FOR PRECIP IN NORTHWEST PORTIONS OF OUR CWA...SUCH
AS ORANGE COUNTY AS CONFIDENCE HAS GROWN. LIGHT TO MODERATE SHOWERS
WILL THEN SPREAD QUICKLY EAST OVER THE ENTIRE REGION BY FRIDAY
EVENING. THE SYSTEM WILL EXIT THE REGION AND PRECIPITATION CHANCES
DWINDLE SATURDAY MORNING. THE SNOW LEVEL FRIDAY NIGHT WILL DROP TO
BETWEEN 6000-6500 FEET WITH ONLY A COUPLE INCHES OF SNOW EXPECTED
ABOVE THIS ELEVATION. THE LATEST SMALL SCALE MODELS INDICATE DECENT
MOISTURE AND OROGRAPHIC LIFT...THEREFORE HAVE INCREASED THE AMOUNTS
RAINFALL IN THE MOUNTAINS AND SURROUNDING FOOTHILLS. LATEST FORECAST
PRECIP AMOUNTS...COASTAL AREAS 0.15" TO 0.35" HIGHEST IN ORANGE
COUNTY...0.35" TO 0.50" THE IN THE INLAND VALLEYS...NEAR A QUARTER
INCH IN THE INLAND EMPIRE...0.50" TO 1.00" IN THE MOUNTAINS...0.10"
TO 0.15" IN THE UPPER DESERTS...AND LESS THAN 0.05" IN THE LOWER
DESERTS.

THIS WEEKEND INTO EARLY NEXT WEEK...A MOIST ZONAL FLOW WILL CONTINUE
OVER THE REGION...MAINTAINING ONSHORE FLOW AND COOLER WEATHER.
INLAND HIGH TEMPERATURES WILL MAINLY BE 5 TO 10 DEGREES BELOW
NORMAL. A WEAK TROUGH WILL PASS TO THE NORTH OF REGION SUNDAY
EVENING THROUGH EARLY TUESDAY. MOISTURE AND OROGRAPHIC LIFT OVER
SOUTHERN CALIFORNIA WILL GIVE WAY TO A SLIGHT CHANCE OF LIGHT
SHOWERS DURING THIS TIME FRAME. LONG RANGE MODELS BUILD A LARGE DOME
OF HIGH PRESSURE OVER THE WEST COAST BY MID WEEK...BRINGING A RETURN
TO WARM AND DRY WEATHER.
