SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
422 PM PST TUE NOV 10 2015

UPDATED AVIATION SECTION

.SYNOPSIS...

HIGH PRESSURE AND OFFSHORE FLOW WILL BRING CLEAR SKIES AND A WARMING
TREND TO THE REGION WEDNESDAY THROUGH FRIDAY ALONG WITH LOCALLY
GUSTY NORTHEAST WINDS AND VERY LOW HUMIDITIES. AN UPPER LOW WILL
BRING COOLING SUNDAY AND MONDAY...WITH A SLIGHT CHANCE OF RAIN TO
NORTHERN AREAS.

&&

.SHORT TERM (TODAY-FRI)...TYPICAL POST-FRONTAL WIND ISSUES TODAY AND
TONIGHT WITH AREAS EXPOSED TO WEST/NORTHWEST FLOW SEEING THE
STRONGEST WINDS. ADVISORIES ARE UP FOR SRN SBA COUNTY, I5 CORRIDOR,
AND THE ANTELOPE VALLEY WHICH HAS SEEN SOME LOW VSBYS AT TIMES DUE
TO BLOWING DUST AND SAND. FLOW QUICKLY SHIFTS TO NORTHEAST OVERNIGHT
TONIGHT AND WEAKENS CONSIDERABLY. AS THE WINDS DROP OFF SO WILL THE
TEMPS. DRY AIR IN PLACE WILL ALLOW LOWS TO DROP INTO THE 30S IN WIND
PROTECTED INLAND LOCATIONS AND IN THE 20S IN THE ANTELOPE VALLEY. A
HARD FREEZE WARNING WILL BE IN EFFECT THERE THOUGH IT'S A LITTLE
TRICKY THERE WITH THE WIND TONIGHT AND WHETHER IT DECREASES SOON
ENOUGH TO ALLOW TEMPS TO DROP BELOW 28.

AFTER A COOL START TO THE MORNING VETERANS DAY SHOULD BE QUITE
PLEASANT WITH HIGHS IN THE LOW TO MID 70S, THOUGH IT WON'T LIKELY
EVEN FEEL THAT WARM GIVEN THE LOW HUMIDITIES NORTHERLY BREEZES. WITH
LESS WIND TOMORROW AND STILL A COLD AIR MASS IN PLACE LOOK FOR LOWS
WEDNESDAY NIGHT TO BE EVEN COLDER ACROSS INTERIOR AREAS SO A BETTER
CHANCE FOR MORE WIDESPREAD HARD FREEZE CONDITIONS ACROSS THE
ANTELOPE VALLEY THAN TONIGHT.

INCREASING SANTA ANA CONDITIONS ON TAP THU/FRI WITH TEMPS WARMING UP
TO THE HIGH 70S OR LOW 80S FOR LOWER ELEVATIONS. VERY SIMILAR TO
LAST FRIDAY, THOUGH UPPER SUPPORT FOR OFFSHORE WINDS IS 5-10 KT
WEAKER SO NORTHEAST WINDS LIKELY WILL NOT BE QUITE AS STRONG AS THEY
WERE LAST WEEK.

.LONG TERM (SAT-TUE)...GRADIENTS WILL START TRENDING ONSHORE
SATURDAY SO FRIDAY LIKELY TO BE THE WARMEST DAY FOR COAST/VALLEYS,
BUT PROBABLY ONLY BY A DEGREE OR TWO. STILL SEVERAL DEGREES ABOVE
NORMAL FOR MID NOVEMBER. THE NEXT TROUGH HAS VERY SIMILAR
CHARACTERISTICS AS THIS LAST STORM DID, THOUGH PERHAPS EVEN A BIT
FURTHER NORTH AND MORE INSIDE THAN THIS ONE. TIMING IS EVEN SIMILAR
WITH THE INITIAL FRONT COMING THROUGH LATE SUNDAY, FOLLOWED BY
INCREASING NORTHWEST FLOW MONDAY, THEN ANOTHER SANTA ANA WIND EVENT
NEXT TUE/WED. THE SUNDAY FRONT MAY HOLD TOGETHER JUST LONG ENOUGH TO
BRING SOME LIGHT PRECIP TO AREAS NORTH OF PT CONCEPTION AND THE
MOUNTAINS BUT THAT'S ABOUT IT. LONGER RANGE MODELS SHOW THIS PATTERN
HOLDING THROUGH THE 20TH OF NOV SO ESSENTIALLY VERY LITTLE OR NO
RAIN WITH PERIODS OF VERY DRY AND GUSTY SANTA ANA WINDS.

&&
