ASR

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
353 PM PST MON FEB 22 2016

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...
THE WARMING TREND WILL CONTINUE THROUGH WEDNESDAY AS OFFSHORE FLOW
COMBINES WITH BUILDING HIGH PRESSURE ALOFT. AN APPROACHING LOW
PRESSURE SYSTEM WILL ALLOW ONSHORE FLOW AND A COOLING TREND TO
DEVELOP LATER THIS WEEK INTO THE WEEKEND.

&&

.SHORT TERM...(TDY-THU)

STRONG NORTHERLY FLOW STARTING TO SHIFT TO THE NORTHEAST AS
SURFACE HIGH PRESSURE STRENGTHENS OVER NEVADA. AREAS THAT ARE MORE
SUSCEPTABLE TO NORTH WINDS WILL SEE WINDS DECREASE TODAY WHILE THE
TYPICAL SANTA ANA WIND (EAST AND NORTHEAST) LOCATIONS WILL PICK
UP TONIGHT AND TUESDAY. SO A MIXED BAG OF WIND TRENDS THE NEXT 24
HOURS OR SO. WHILE THE LAX-DAG GRADIENT IS EXPECTED TO TOP OUT AT
A RATHER ROBUST -6MB, THE UPPER SUPPORT IS MARGINAL AT BEST AND AT
THIS TIME I'M INCLINED TO HOLD OFF WITH ANY ADDITIONAL ADVISORIES.
IT MIGHT ULTIMATELY BE A LOW END ADVISORY EVENT FOR SOME OF THE
MTNS, VALLEYS, AND POSSIBLY EVEN VENTURA COAST BUT IT'S DEFINITELY
ON THE FENCE RIGHT NOW BASED ON CURRENT PROJECTIONS. EITHER WAY,
HIGHS EXPECTED TO CLIMB ANOTHER FEW DEGREES WITH MID 80S FAIRLY
WIDESPREAD IN THE VALLEYS AND SOME 80S FOR THE COASTAL AREAS AS
WELL.

NOT A WHOLE LOT OF CHANGE IN THE PATTERN THROUGH THURSDAY. WED
GRADIENTS ACTUALLY A TOUCH STRONGER BUT AGAIN MARGINAL UPPER
SUPPORT. IF ADVISORIES END UP NEEDED TUE THEN THEY LIKELY WILL
AGAIN FOR WED. THEN DEFINITELY WEAKER THU AND ACTUALLY TURNING
ONSHORE BY AFTERNOON. SO LOOK FOR SIMILAR TO SLIGHTLY WARMER TEMPS
WED OVER TUE, THEN LIKELY SOME COOLING FOR COASTAL AREAS THU WHILE
FATHER INLAND AREAS ARE ABOUT THE SAME.

.LONG TERM...(FRI-MON)

THE RIDGE WILL BREAK DOWN AND SHIFT EAST FRI AND SAT AS A WEAK
TROUGH PUSHED ONSHORE ALONG THE WEST COAST. AT ONE TIME THE MODELS
HAD SHOWN SOME PRECIP FOR AT LEAST NORTHERN AREAS WITH THIS ONE
BUT THE LAST SEVERAL RUNS HAVE BACKED OFF THIS IDEA AND NOW
ABOUT THE BEST WE CAN EXPECT IS COOLER TEMPS AND POSSIBLY SOME
MARINE LYR CLOUDS RETURNING TO COAST/VALLEYS. THEN WEAK RIDGING
RETURNS SUNDAY THROUGH EARLY NEXT WEEK FOR A SLIGHT WARMING TREND.
STILL NO SIGNS OF ANY SIGNIFICANT PATTERN CHANGES THROUGH THE
FIRST WEEK IN MARCH OR SO.

&&
