MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO

ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
1000 AM PDT SAT AUG 2 2014

.SYNOPSIS...
UPPER LEVEL LOW PRESSURE SYSTEM WILL SLOWLY MOVE OVER SOUTHERN
CALIFORNIA TODAY AND SUNDAY...BRINGING COOLER CONDITIONS AS WELL AS
UNSETTLED WEATHER.  SHOWERS AND THUNDERSTORMS WILL INCREASE IN
COVERAGE TODAY...WITH THE THREAT CONTINUING INTO SUNDAY.  THE
GREATEST PRECIPITATION AMOUNTS WILL BE IN THE MOUNTAINS...BUT SOME
PRECIPITATION IS POSSIBLE ALONG THE COAST AS WELL.  THERE IS A ALSO
THREAT FOR FLASH FLOODING IN THE MOUNTAINS AND DESERTS.  DRIER
CONDITIONS WILL DEVELOP FOR THE WORK WEEK...AS A TROUGH DEVELOPS
ALONG THE CALIFORNIA COAST.  THEREFORE...EXPECT ONSHORE FLOW TO
RETURN...WITH TEMPERATURES RUNNING A FEW DEGREES BELOW NORMAL AND A
SLIGHTLY DEEPER MARINE LAYER POSSIBLE.

&&

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

WATER VAPOR IMAGERY SHOWS EAST TO SOUTHEASTERLY FLOW ALOFT OVER
SOUTHERN CALIFORNIA THIS MORNING...WITH A COUPLE OF DISTURBANCES
CLEARLY DEFINED AT THIS TIME.  THE FIRST OF WHICH IS MOVING ACROSS
SOUTHEASTERN CALIFORNIA THIS MORNING...WITH A SECONDARY MORE
IMPRESSIVE CIRCULATIONS OVER NORTHERN BAJA.  THESE TWO DISTURBANCES
ARE STARTING TO INTERACT WITH ONE ANOTHER...AND WILL WRAP INTO ONE
ANOTHER LATER TODAY AND TONIGHT...BEFORE LIFTING OUT OF THE REGION
LATE SUNDAY.  THIS FEATURE WILL BE ARE PRIMARY WEATHER MAKER OVER
THE NEXT 48 HOURS...BRINGING COOLER CONDITIONS TO THE REGION AS WELL
AS SOME MUCH NEEDED RAIN AS WELL AS SOME THUNDERSTORMS.

CURRENT RADAR IMAGERY SHOWS THESE TWO DISTURBANCES QUITE WELL.  THE
NORTHERN DISTURBANCES IS BRINGING SCATTERED THUNDERSTORMS TO EASTERN
SAN BERNARDINO COUNTY.  THESE STORMS ARE DRIFTING TO THE WEST...WITH
THE LEADING EDGE APPROACHING TWENTYNINE PALMS AND THE LANDERS AREA.
MEANWHILE...THE SOUTHERN PORTION...WHICH IS MAINLY OVER IMPERIAL AND
EASTERN SAN DIEGO COUNTIES...IS TURNING INTO A BROAD BAND OF LIGHT
TO MODERATE SHOWERS...AS MOST OF THIS MOISTURE IS STILL QUITE
ELEVATED.  FOR THIS REASON...OUR MOUNTAIN RAIN GAGES ARE ONLY
REPORTING A FEW HUNDREDTH AT BEST ACROSS SAN DIEGO COUNTY AT THIS
TIME.  HOWEVER...THERE ARE STILL SOME EMBEDDED THUNDERSTORMS WITHIN
THIS BAND THAT ARE CAPABLE OF PRODUCING BRIEF HEAVY RAIN.  NEEDLESS
TO SAY...THE THREAT OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
INCREASE THROUGH THE DAY TODAY...AND CONTINUE THROUGH SUNDAY FOR
MOST OF THE AREA.  AT THIS TIME...THINK THE COASTAL AREAS WILL HAVE
THE BEST CHANCE OF SOME RAIN LATER TODAY AND TONIGHT...WITH THE
THREAT DECREASING DURING THE DAY ON SUNDAY.

AS THIS DISTURBANCES LIFTS OFF THE OUR NORTHEAST ON SUNDAY NIGHT AND
MONDAY...DRIER CONDITIONS WILL DEVELOP ACROSS SOUTHERN CALIFORNIA.
MODELS SHOW A TROUGH DEVELOPING ALONG THE CALIFORNIA COAST FOR THE
WORK WEEK.  ONSHORE FLOW WILL PREVAIL...WITH LOCALLY GUSTY WINDS
POSSIBLE EACH AFTERNOON AND EVENING IN THE MOUNTAINS AND DESERTS.
OTHERWISE...EXPECT THE MARINE LAYER TO DEEPEN A BIT...WITH LOW
CLOUDS AND FOG POSSIBLE ALONG THE COAST EACH NIGHT.  TEMPERATURES
WILL ALSO REMAIN A FEW DEGREES BELOW NORMAL DURING THIS TIME.

&&

.AVIATION...
021500Z...MULTIPLE LAYERS OF CLOUDS AT OR ABOVE 8000 FEET WILL
CONTINUE AFTER THE EARLY MORNING LOW CLOUD LAYER OF 1200 FEET
CLEARS. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL MOVE FROM
SOUTHEAST TOWARD THE NORTHWEST TODAY AND CONTINUE THROUGH SUNDAY.
CONFIDENCE IS LOW ON EXACT TIMING AND LOCATION OF TSTORMS...BUT MOST
LIKELY IN SAN DIEGO COUNTY. HIGHER CONFIDENCE ON TSTORMS THIS
AFTERNOON OVER MOUNTAINS AND DESERTS...WHICH COULD CONTAIN HEAVY
RAIN AND STRONG DOWNDRAFTS. LOW CLOUDS WILL RETURN IN RANDOM FASHION
AROUND KSAN AND KCRQ OVERNIGHT WITH SIMILAR BASES AROUND 1000 FEET
MSL AND SCATTER OUT BY 15-16Z SUNDAY.

&&

.MARINE...
800 AM...THERE WILL BE A CHANCE OF SHOWERS AND SLIGHT CHANCE OF
THUNDERSTORMS FOR THE COASTAL WATERS THROUGH SUNDAY. LOW CONFIDENCE
ON TIMING. TSTORMS WILL BE CAPABLE OF PRODUCING BRIEF HEAVY
RAIN...CLOUD TO WATER LIGHTNING...AND BRIEF GUSTY WINDS.
OTHERWISE...NO MARINE HAZARDS ARE EXPECTED THROUGH WEDNESDAY.
