AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT THU APR 4 2013

.SYNOPSIS...
A LOW PRESSURE TROUGH WILL APPROACH FROM THE WEST TODAY AND BRING
COOLING...ESPECIALLY WEST OF THE MOUNTAINS. THE TROUGH WILL BRING A
DEEP MARINE LAYER TONIGHT WHICH WILL RESULT IN WIDESPREAD LOW CLOUDS
AND PATCHY DRIZZLE OR LIGHT SHOWERS FROM THE COASTAL MOUNTAIN SLOPES
WEST TO THE COAST. STRONG GUSTY WEST WINDS WILL DEVELOP IN THE
MOUNTAINS AND DESERTS LATE TONIGHT AND CONTINUE AT TIMES THROUGH
SATURDAY. THE MARINE LAYER WILL BECOME MORE SHALLOW OVER THE WEEKEND
FOR LESS EXTENSIVE LOW CLOUDS AND SLIGHT WARMING. UPPER LEVEL LOW
PRESSURE WILL MOVE THROUGH THE GREAT BASIN MONDAY AND TUESDAY AND
BRING WINDY COOL CONDITIONS TO THE REGION...FOLLOWED BY WARMING
AROUND MIDWEEK UNDER BUILDING HIGH PRESSURE.

&&

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

STRATUS COVERED COASTAL AREAS AND MOST VALLEYS THIS MORNING...WITH A
LOT OF HIGH CLOUDS OVER THE REGION. AN UPPER LOW WAS NEAR 40N/130W
AND WAS BRINGING SOME SUBTROPICAL MOISTURE INTO CENTRAL CALIFORNIA
WITH PRECIPITABLE WATER OF AROUND ONE INCH THERE...WITH GREATEST
MOISTURE BETWEEN 800 AND 600 MB. MOISTURE WILL INCREASE IN THE LOW
LEVELS HERE DUE TO A DEEPENING MARINE LAYER WITH A VORT MAX MOVING
THROUGH SO-CAL BY 12Z FRI. MOST OF THE MOISTURE WILL BE BELOW 850
MB...BUT WITH THE NOCTURNAL PASSAGE OF THE VORT MAX...THERE SHOULD
BE A FEW LIGHT SHOWERS...WITH PRECIP AMOUNTS MOSTLY A FEW HUNDREDTHS
OF AN INCH OR LESS...WITH BEST AMOUNTS ON W-FACING SLOPES DUE TO
LOW-LEVEL W-NW FLOW. STRONG WINDS WILL DEVELOP IN THE
MTNS/DESERTS...DUE TO THE INCREASED THERMAL GRADIENT BETWEEN THE
VALLEYS AND DESERTS AND THE STRONGER SURFACE PRESSURE GRADIENTS.
LOCAL WRF SHOWS 850 MB WINDS UP TO 40 KNOTS TONIGHT AND AROUND 45
KNOTS FRIDAY NIGHT...BUT MTN WAVE ACTIVITY WILL NOT BE TOO STRONG
DUE TO AN INSUFFICIENT STABLE LAYER ALOFT.

ANOTHER WEAK SHORT WAVE WILL MOVE QUICKLY THROUGH THE FLOW FROM WNW
TO ESE FRI NIGHT WITH POSSIBLY A WEAKER ONE SATURDAY. OVERALL...THE
WEEKEND SHOULD BE FAIR EXCEPT FOR THE NIGHT/MORNING LOW CLOUDS/FOG W
OF THE MTNS UNDER A SLIGHTLY MORE SHALLOW MARINE LAYER AS THE FLOW
BECOMES MORE NW...AND WINDY CONDITIONS CONTINUING IN THE DESERTS.

STRONG UPPER LOW AND SURFACE LOW WITH ORIGINS FROM THE GULF OF
ALASKA WILL MOVE THROUGH NEVADA/UTAH EARLY NEXT WEEK. THIS WILL MOST
LIKELY BRING WINDY CONDITIONS TO SO-CAL...FIRST FROM W/NW WINDS
MON...THEN POSSIBLY STRONG OFFSHORE FLOW TUE/WED. THIS WILL MOSTLY
BE A DRY SYSTEM HERE VERSUS IN THE INTERIOR WESTERN US...THOUGH
ENOUGH MOISTURE COULD EXIST FOR A FEW SHOWERS HERE. AFTER TEMPS A
LITTLE COOLER THAN NORMAL MONDAY...TEMPS SHOULD INCREASE TUE/WED
WITH LOTS OF 80S POSSIBLE W OF THE MTNS BY WED.
