SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1250 PM PDT SUN APR 13 2014

.SYNOPSIS...

ONE MORE DAY OF COOL TEMPERATURES WEST OF THE MOUNTAINS FOR TODAY
BEFORE HIGH PRESSURE COMBINES WITH OFFSHORE FLOW FOR MUCH WARMER
TEMPERATURES MONDAY INTO TUESDAY. TEMPERATURES WILL GRADUALLY COOL
FOR THE REMAINDER OF THE WEEK AS ONSHORE FLOW AND MORNING COASTAL
CLOUDS RETURN WEST OF THE MOUNTAINS.

&&

.SHORT TERM (TODAY-WED)...WE ARE TRANSITIONING TO A ONE DAY WEAK TO
MODERATE OFFSHORE FLOW PATTERN TONIGHT INTO MONDAY. NAM HAS DIALED
BACK THE WINDS A NOTCH OR TWO FROM ITS INITIAL SWING AT IT ON FRIDAY
AND NOW LOOKS SIMILAR TO THE WEAKER GFS/ECMWF SOLUTIONS. STILL, EVEN
THOUGH THE MODEL SOLUTIONS HAVE TRENDED LIGHTER THE WINDS STILL
SHOULD BE AT LEAST LOW END ADVISORY LEVEL IN THE MTNS AND SOME OF
THE VALLEYS OF VENTURA/LA COUNTIES. AND ALONG WITH THOSE WINDS WILL
COME A SIGNIFICANT JUMP IN TEMPS WITH HUMIDITIES DROPPING INTO THE
TEENS AND LOCALLY SINGLE DIGITS. IF IT WEREN'T FOR THE BIG INCREASE
RECENTLY IN FUEL MOISTURES THIS WOULD DEFINITELY BE A RED FLAG
SITUATION, BUT THE WETTER FUELS PRECLUDES THE ISSUANCE OF ANY
HIGHLIGHTS AT THIS TIME. THE OTHER FACTOR IS THAT THIS IS EXPECTED
TO BE A ONE-OFF EVENT AS WE TRANSITION TO ONSHORE FLOW TUESDAY.
STILL EXPECTING A PRETTY WARM AND DRY DAY TUESDAY, ESPECIALLY
INLAND, BUT WITHOUT THE WIND. THE ONSHORE TRENDS MAY ACTUALLY
PRESENT AN ELEVATED FIRE RISK IN AND AROUND THE ANTELOPE VALLEY
TUESDAY AFTERNOON AS A PRETTY STRONG ONSHORE PUSH DEVELOPS, BUT
AGAIN THE HIGHER FUEL MOISTURE LIKELY WILL KEEP RISK MINIMAL.

COASTAL AREAS EXPECTED TO GET IN ON THE WARM/BREEZY CONDITIONS AS
WELL MONDAY, THOUGH IT REMAINS TO BE SEEN HOW QUICKLY THIS DEEP
MARINE INVERION LINGERS. THE NAM HAS BEEN PRETTY CONSISTENT SHOWING
A RAPIDLY LOWERING INVERSION THIS EVENING AS THE SANTA ANA WINDS
START TO SURFACE IN THE MTNS AND HIGHER VALLEYS. THE GFS AND ECMWF,
HOWEVER, HAVE BEEN MUCH MORE CONSERVATIVE WITH THEIR FORECASTS. FOR
NOW AM LEANING TOWARDS THE WARMER/BREEZIER NAM SOLUTION BUT
CONFIDENCE NOT 100%.

NOT EXPECTING ANY TEMPERATURE RECORDS NEXT COUPLE DAYS AS THE
RECORDS ARE ALL WELL UP INTO THE 90S. EVEN THE WARMEST ESTIMATES FOR
TOMORROW KEEP HIGHS AT LEAST A FEW DEGREES BELOW RECORD LEVELS. AND
RECORDS FOR TUESDAY ARE EVEN WARMER, WHILE MOST COAST/VALLEY
LOCATIONS SHOULD BE AT LEAST A FEW DEGREES COOLER WITH THE ONSHORE
TRENDS.

HIGHS EXPECTED TO DROP BACK TO NEAR NORMAL LEVELS BY WEDNESDAY WITH
SOME MARINE LYR RETURNING TO COASTAL AREAS.

.LONG TERM (THU-SUN)...A PRETTY BLAND WEATHER PATTERN THROUGH THE
WEEKEND. A WEAK TROF THU WILL LIKELY YIELD A SOMEWHAT DEEPER MARINE
LYR THROUGH SATURDAY. ON SUNDAY THE ECMWF IS QUITE A BIT STRONGER
WITH A POSITIVELY TILTED UPPER RIDGE MOVING OVERHEAD ON SUNDAY. THE
GFS HAS SOME INCREASE IN HEIGHTS BUT MUCH LESS SO THAN THE EC. SO
SOME WARM UP IS EXPECTED BY SUNDAY BUT STILL TOO EARLY TO SAY HOW
MUCH.

&&

.AVIATION...13/1735Z...

OVERALL...LOW TO MODERATE CONFIDENCE IN 18Z TAF PACKAGE. DEEP AND
WEAK INVERSION IN PLACE ACROSS THE AREA. CURRENT MVFR CIGS NORTH OF
POINT CONCEPTION WILL CLEAR OUT BY 20Z...WHILE SOUTH OF POINT
CONCEPTION A COMBO OF MVFR/VFR CIGS WILL LIKELY CONTINUE THRU MID
AFTERNOON BEFORE DISSIPATING.

FOR TONIGHT...FORECAST IS LOW CONFIDENCE FOR COASTAL TAF. THE MARINE
INVERSION IS EXPECTED TO BECOME MORE SHALLOW THIS EVENING/OVERNIGHT
WHILE OFFSHORE FLOW DEVELOPS. SO...EXPECT INLAND AREAS TO REMAIN
CLEAR. HOWEVER...COASTAL TAF SITES WILL POTENTIALLY SEE A RETURN OF
SOME MVFR CIGS...BUT CONFIDENCE IN RETURN/TIMING/HEIGHT OF CIGS IS
LOW.

KLAX...LOW CONFIDENCE IN 18Z TAF. CURRENT MVFR/VFR CIGS COULD LINGER
BEYOND CURRENT 20Z CLEARING FORECAST. FOR TONIGHT...LOW CONFIDENCE IN
RETURN OF STRATUS AS WELL AS ITS HEIGHT (IF IT DOES RETURN).

KBUR...MODERATE CONFIDENCE IN 18Z TAF. THERE IS A 35% CHANCE OF MVFR
CIGS BETWEEN 18Z AND 23Z THIS AFTERNOON. FOR TONIGHT...THE
DEVELOPING OFFSHORE FLOW SHOULD KEEP THE AIRFIELD CLEAR AND PRODUCE
SOME LLWS/TURBULENCE AFTER 10Z.
