High Wind in California, April 14, 2009

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
125 PM PDT TUE APR 14 2009

.SHORT TERM (TODAY-FRI)...WINDY CONDITIONS THE NEXT COUPLE OF DAYS
WITH ADVISORIES AND WARNINGS CURRENTLY IN EFFECT. REALLY NO CHANGES
TO THAT ASPECT OF THE FORECAST. THE UPPER LOW RESPONSIBLE FOR THESE
WINDS IS MOVING THROUGH CENTRAL CALIFORNIA THIS AFTERNOON WITH THE
HIGH CLOUD SHIELD FINALLY MOVING EAST ALLOWING MORE SUNSHINE TO
REACH THE SURFACE. GETTING A FEW CU CLOUDS DEVELOPING NEAR THE LOW
ACROSS SLO COUNTY BUT NOT ENOUGH MOISTURE TO GENERATE ANY SHOWERS.
THE COLD AIR BEHIND THE DRY COLD FRONT WILL MAKE FOR SOME CHILLY
CONDITIONS TONIGHT, ESPECIALLY IN AREAS THAT ARE SHELTERED FROM THE
WINDS LIKE THE OJAI VALLEY AND SOME OF THE HIGHER MOUNTAIN VALLEYS.
PATCHY FROST IS POSSIBLE ACROSS THE INTERIOR, THOUGH WINDS SHOULD
KEEP THE BOUNDARY LAYER WELL MIXED ENOUGH TO PREVENT ANY WIDESPREAD
FROST FROM DEVELOPING.

WINDS WILL KICK UP AGAIN WED AND AREAS WHERE THE WINDS DROP OFF
TONIGHT SHOULD PICK UP TO NEAR OR ABOVE ADVISORY LEVELS BY
AFTERNOON. HIGHS WED WILL BE SEVERAL DEGREES BELOW NORMAL DESPITE
THE AMPLE SUNSHINE.

WINDS WILL BE DROPPING OFF WEDNESDAY NIGHT AND THURSDAY, ALLOWING
MORE WIDESPREAD COLD TEMPERATURES TO DEVELOP. PERHAPS ENOUGH AREAL
COVERAGE TO WARRANT FROST ADVISORIES ACROSS SLO/SBA COUNTIES AND
PATCHY FROST ACROSS THE VALLEYS OF LA/VENTURA COUNTIES. LOWS MAY
EVEN APPROACH RECORD LEVELS IN A FEW AREAS SUCH AS PASO ROBLES WHERE
THE RECORD LOW IS 30.

AIRMASS FINALLY STARTS TO RECOVER THURSDAY AFTERNOON THROUGH FRIDAY
AS THIS UPPER LOW SLOWLY TREKS TO THE EAST. MOST AREAS SHOULD SEE
5-10 DEGREES OF WARMING THURSDAY AND ANOTHER 5-10 FRIDAY, PUSHING
HIGHS IN THE VALLEYS INTO THE LOW TO MID 80S. GRADIENTS WILL BE
WEAKLY OFFSHORE BUT NOT ENOUGH TO GENERATE ANY SIGNIFICANT WINDS.

.LONG TERM (SAT-TUE)...JUST A SPECTACULAR SET OF DAYS ON TAP FROM
THE WEEKEND INTO THE MIDDLE PART OF NEXT WEEK. WEAK OFFSHORE FLOW
AND A BUILDING RIDGE ALOFT WILL PUSH INLAND HIGHS WELL INTO THE 80S
AND EVEN POSSIBLY LOWER 90S BY SUNDAY. BEACHES WILL BE COOLER BUT
WITH THE WEAK OFFSHORE FLOW IN PLACE EVEN MOST COASTAL AREAS WILL
REACH THE 70S, WITH EVEN A FEW LOWER 80S SPRINKLED IN. SKIES SHOULD
REMAIN CLEAR THROUGH THE PERIOD WITH LITTLE CHANCE THAT ANY MARINE
LYR WILL REFORM.

&&

.AVIATION...14/2000Z.
POOR CONFIDENCE IN CLOUD COVERAGE FOR COASTAL TAFS AS THE DEVELOPING
TROUGH ALOFT IS CAUSING DISRUPTIONS IN THE MARINE CLOUD DECK. THE
CEILINGS WILL CONTINUE TO WAVER FROM SCT TO BKN WITH BKN CONDITIONS
CAUSING MVFR TO OCCASIONAL IFR CEILINGS. EVENTUALLY...THE
ANTICIPATED STRONG WINDS AND COOLING ASSOCIATED WITH THE TROUGH WILL
SHRED THE MARINE DECK ONCE AND FOR ALL...PROBABLY BY THIS EVENING.
THE OTHER HAZARD TODAY WILL BE VERY STRONG WINDS AT ALL
ALTITUDES...AS A NORTHERLY JET STREAM DESCENDS OVER THE FORECAST
AREA. THE VERY STRONG WINDS WILL LIKELY CAUSE AREAS OF STRONG
TURBULENCE AND LOW LEVEL WIND SHEAR AT MANY LOCATIONS.

KLAX AND KBUR...VERY LOW CONFIDENCE IN MARINE CLOUD
COVERAGE...MAINLY NEAR THE COAST. GOOD CONFIDENCE IN INCREASING
WINDS AT ALL LEVELS THIS AFTERNOON THROUGH EARLY WEDNESDAY CAUSING
STRONG TURBULENCE AND LOW LEVEL WIND SHEAR.
