741 PM PDT THU MAY 22 2014

...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 900 PM PDT FOR
SOUTHEASTERN SAN LUIS OBISPO AND NORTH CENTRAL SANTA BARBARA
COUNTIES...

AT 735 PM PDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED 
RAINFALL TAPERING OFF OVER THE WARNED AREA. EARLIER RAINFALL RATES 
EXCEEDED 2 INCHES PER HOUR. DRAINAGES AND WASHES MAY STILL BE 
FLOWING AND FLASH FLOODING IS IMMINENT OR OCCURRING OVER THE WARNED 
AREA. MOTORISTS ARE ADVISED TO USE CAUTION AS WATER MAY BE FLOWING 
ACROSS HIGHWAYS AND AREA ROADWAYS...ESPECIALLY AT LOW WATER 
CROSSINGS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE
DANGERS OF FLOODING. IF FLASH FLOODING IS OBSERVED ACT QUICKLY. MOVE
UP TO HIGHER GROUND TO ESCAPE FLOOD WATERS. DO NOT STAY IN AREAS
SUBJECT TO FLOODING WHEN WATER BEGINS RISING.

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

TO REPORT FLOODING...HAVE THE NEAREST LAW ENFORCEMENT AGENCY RELAY
YOUR REPORT TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN
OXNARD.

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
115 PM PDT THU MAY 22 2014

.SYNOPSIS...

AN UPPER LEVEL LOW PRESSURE SYSTEM WILL BRING A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS TO PARTS OF THE AREA THROUGH THIS EVENING.
AS THE UPPER LOW SLOWLY MOVES EAST AND HIGH PRESSURE RETURNS...A
WARMING TREND IS EXPECTED THROUGH THE WEEKEND FOR INLAND AREAS. THE
WARMING TREND WILL COME TO AN END EARLY NEXT WEEK AS A WEAK TROUGH
APPROACHES FROM THE NORTH.

&&

.SHORT TERM (TODAY-SUN)...AN UPPER LOW DROPPING OVER THE AREA TODAY
IS CAUSING ISOLATED SHOWERS AND THUNDERSTORMS, MAINLY OVER VENTURA
AND LA COUNTIES, THOUGH A FEW SPRINKLES OR LIGHT SHOWERS ARE
POSSIBLE AS FAR WEST AS THE SANTA YNEZ VALLEY. THUNDERSTORMS SO FAR
HAVE BEEN CONFINED TO THE MTNS, THOUGH A 20-25KT NORTHERLY STEERING
FLOW IS CAUSING THOSE TO DRIFT SOUTH TOWARDS THE VALLEYS AND COAST.
THE STEERING FLOW IS MUCH WEAKER CLOSER TO THE LOW CENTER OVER LA
COUNTY SO SHOWERS AND THUNDERSTORMS THERE ARE MUCH SLOWER MOVING AND
WILL LIKELY GENERATE MORE RAINFALL OVER ONE SPOT THAN THE STORMS TO
THE WEST. SO FAR RAIN AMOUNTS HAVE BEEN LESS THAN A TENTH OF AN INCH
TOTAL, BUT A DECREASE IN MID/UPPER LEVEL CLOUD COVERAGE THROUGH THE
AFTERNOON AS WELL AS FURTHER DESTABILIZATION OF THE AIR MASS SHOULD
LEAD TO STRONGER STORMS AND HEAVIER RAIN AMOUNTS. SHOWERS AND STORMS
ARE EXPECTED TO DECREASE LATER IN THE EVENING AS WE LOSE THE HEATING
AND THE UPPER LOW SHIFTS SOUTH AND EAST.

WE SHOULD RETURN TO NORMAL CONDITIONS FRIDAY WITH A STANDARD MARINE
LYR COVERAGE AND TEMPS NEAR NORMAL. MODELS DO SHOW SOME DECENT
INSTABILITY OVER THE VENTURA/LA MTNS IN THE AFTERNOON BUT A
SUBSTANTIAL DECREASE IN MOISTURE AND TEMPS ALOFT WARMING SHOULD PUT
A DAMPER ON ANY TSTORM HOPES. WE LIKELY WILL SEE SOME AFTERNOON
BUILDUPS OVER THE MTNS AND I DID BUMP POPS UP A FEW PERCENT BUT KEPT
PRECIP OUT OF THE OFFICIAL FORECAST.

HIGH PRESSURE WILL BUILD INTO THE AREA OVER THE WEEKEND LEADING TO A
LOWERING, THOUGH STRENGTHENING MARINE INVERSION AND A WARMUP FOR
AREAS AWAY FROM THE BEACHES. SHOULD SEE ABOUT A 3-5 DEGREE INCREASE
IN HIGHS EACH DAY THIS WEEKEND, WITH VALLEYS IN THE MID 80S BY
SUNDAY. LOW CLOUDS WILL REACH THE VALLEYS SATURDAY BUT PROBABLY NOT
SUNDAY AS THE INVERSION LOWERS TO UNDER 1500 FT. A STRONG ONSHORE
PUSH DURING THE AFTERNOON WILL LIKELY KEEP CLOUDS LINGERING NEAR THE
BEACHES MOST OF THE DAY.

.LONG TERM (MON-THU)...WARMEST DAY IN THIS STRETCH EXPECTED TO BE ON
MEMORIAL DAY WITH VALLEYS CLOSE TO 90 AND HOPEFULLY EARLIER MARINE
LYR BURNOFF FOR THE BEACHES. STILL A PRETTY STRONG ONSHORE FLOW SO
AT LEAST SOME CLOUDS EXPECTED FOR COASTAL AREAS INTO THE AFTERNOON.
THE RIDGE WILL START TO FLATTEN OUT TUE WITH WEAK TROFFING
DEVELOPING ALONG THE COAST BY WED AND THU. THE ECMWF CONTINUES TO BE
A LITTLE MORE AGRESSIVE WITH THE HEIGHT FALLS FOR MID WEEK BUT
EITHER WAY WE'RE LOOKING AT A COOLING TREND STARTING TUESDAY WITH A
SLOWLY DEEPENING MARINE LYR.

&&

.AVIATION...22/1800Z.

MID/UPPER LEVEL TROUGH OF LOW PRESSURE CENTERED EAST OF THE AREA
WILL CONTINUE MOVING EAST. UPPER LEVEL STRONG NORTH WINDS WILL
PREVAIL WHILE MID LEVEL LIGHT TO MODERATE EAST NORTHEAST WINDS
BECOME LIGHT TO MODERATE NORTH NORTHWEST AFTER 23/20Z. ISOLATED
THUNDERSTORMS OVER THE HIGHER TERRAIN WITH TOPS 35-40KFT WILL MOVE
SOUTH OR REMAIN NEARLY STATIONARY. INCREASING STABILITY AND
DECREASING MOISTURE AFTER 23/04Z. FREEZING LEVEL WAS APPROXIMATELY
9.5KFT THIS MORNING WILL DIFFER BY PLUS 2KFT AFTER 23/09Z. WEAK TO
MODERATE ONSHORE PRESSURE GRADIENT THROUGH 23/06Z AND AFTER 23/20Z
OTHERWISE WEAK GRADIENT.

.KLAX...CHANCE CIGS 027 THROUGH 22/20Z THEN CHANCE CIGS 021 BETWEEN
23/09-23/20Z.

.KBUR...CHANCE CIGS 023 THROUGH 22/20Z THEN CHANCE CIGS 035 BETWEEN
22/20-23/03Z. CHANCE CIGS 016 AFTER 23/10Z.

VIRTUALLY CERTAIN - 95-100%
VERY LIKELY       - 80-95%
LIKELY            - 60-80%
CHANCE            - 30-60%
VERY UNLIKELY     - 20% OR LESS

&&

.MARINE...22/100 PM.
TROUGH OF LOW PRESSURE NEAR SHORE WILL SHIFT INLAND THIS EVENING.
SMALL CRAFT ADVISORY CONDITIONS ARE POSSIBLE WITH GUSTS TO 25 KT IN
AN AREA SOUTH OF POINT CONCEPTION TO SANTA ROSA ISLAND FOR A FEW
HOURS THIS EVENING AS A RIDGE OF HIGH PRESSURE OVER THE EASTERN
PACIFIC SHIFTS EAST OVER THE AREA. OTHERWISE SMALL CRAFT ADVISORY
CONDITIONS ARE EXPECTED SATURDAY THROUGH SATURDAY NIGHT NORTH OF
POINT CONCEPTION AND SATURDAY NIGHT IN THE VICINITY OF THE NORTHERN
CHANNEL ISLANDS. THE NORTHWEST WINDS WILLL LIKELY INCREASE AGAIN
SUNDAY AFTERNOON. LOCALLY GENERATED SHORT PERIOD SEAS FROM THE
NORTHWEST AND SMALL LONG PERIOD SWELL FROM THE SOUTH WILL PERSIST.
