SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
325 AM PDT WED MAR 25 2015

UPDATED AVIATION DISCUSSION

.SYNOPSIS...

GUSTY WINDS WILL CONTINUE THROUGH FRIDAY WITH BRIEF LULLS DURING THE
AFTERNOON AND EARLY EVENING HOURS. A WARMING TREND WILL START TODAY
AND CONTINUE THROUGH FRIDAY WITH POSSIBLE RECORD BREAKING HEAT ON
FRIDAY. A SLIGHT COOLING TREND WILL BEGIN OVER THE WEEKEND.

&&

.SHORT TERM (TODAY-FRI)...
WINDS CONTINUE EARLY THIS MORNING WITH SOME SURPRISINGLY STRONG
GUSTS REPORTED AT THE MONTECITO SENSOR (63 MPH) AND WHITAKER PEAK
(83 MPH) LAST NIGHTS WINDS CAME IN A LITTLE STRONGER THAN ADVERTISED
DUE TO SOME COLD AIR ADVECTION THAT WAS NOT PICKED UP ON. A SMALL
MTN WAVE BROKE OVER THE BEVERLY HILLS AREA AND KNOCKED OVER A FEW
TREES CREATING POWER OUTAGES. WIND ADVISORIES COVER ALMOST ALL OF
THE AREA SOUTH OF POINT CONCEPTION EXCEPT FOR THE AV...THE VTA CST
AND THE SGV. ASIDE FROM THE WINDS THE BIG NEWS TODAY WILL BE THE MAX
TEMPS WHICH WILL RISE INTO THE 80S ACROSS ALMOST ALL OF THE CST AND
VLY LOCATIONS.

NORTHEAST OFFSHORE FLOW SETS UP TONIGHT AND WINDS WILL SLOWLY
INCREASE THROUGH THE NIGHT BUT WILL MOST LIKELY REMAIN BLO ADVISORY
LEVELS.

A WINDY AND WARM DAY ON TAP FOR THURSDAY WITH A 583 DM RIDGE
OVERHEAD AND ABOUT 5 MB OF OFFSHORE FLOW FROM BOTH THE NORTH AND THE
EAST. ANOTHER ROUND OF ADVISORIES IS LIKELY FOR MOST OF THE WINDY
SPOTS THROUGHOUT THE LA AND VTA COAST AND VLYS. MAX TEMPS WILL WARM
FURTHER WITH MORE THAN A FEW MAX TEMPS REACHING INTO THE LOWER 90S.
RECORDS ARE FAIRLY HIGH SO EVEN THOUGH IT WILL BE WARM IT LOOKS LIKE
IT WILL NOT BREAK ANY RECORDS.

MORE OF THE SAME FRIDAY BUT THE GRADIENTS WILL BE JUST A LITTLE
WEAKER SO THERE WILL LIKELY BE A LITTLE COOLING NEAR THE BEACHES BUT
THATS ABOUT IT. RECORDS ARE LOWER FRIDAY SO DESPITE THE TEMPS WILL
BE NEARLY THE SAME AS THURSDAY RECORDS ARE LIKELY TO FALL.

.LONG TERM (SAT-TUE)...
EC AND GFS NOW AGREE ON SATURDAYS FORECAST AND BOTH BRING A WEAK
TROF INTO THE AREA WHICH WILL LOWER HEIGHTS AND KNOCK THE OFFSHORE
FLOW DOWN. THERE WILL BE 4 TO 8 DEGREES OF COOLING BUT DESPITE THIS
COOLING MAX TEMPS WILL BE WELL ABOVE NORMAL.

FURTHER COOLING SUNDAY AS A LITTLE CUT OFF LOW SETS UP WEST OF THE
AREA. IT WILL MOVE TO THE SOUTH OF THE AREA AND THUS WILL NOT BRING
MUCH IN THE WAY OF HGT FALLS TO THE AREA.

AND THEN ITS TWO MORE DAYS OF RIDGING AS HIGH PRESSURE BUILDS IN
FROM THE WEST. WEAK OFFSHORE SETS UP MONDAY AND THEN STRONGER NW SFC
FLOW MOVES INTO THE AREA FOR TUESDAY.
