STRONG N-S GRADIENTS WERE THE STORY OVERNIGHT...WITH SBA-SMX GRADIENT
NEAR -5.0 MB AND SBA-BFL GRADIENT RUNNING CLOSE TO -8.0 MB NEAR
MIDNIGHT. GUSTY WINDS SURFACED AT A COUPLE OF LOCATIONS ACROSS THE
SANTA BARBARA COUNTY SOUTH COAST...48 GUSTING TO 57 MPH AT MONTECITO
HILLS AND NORTH WINDS GUSTING TO 45 MPH THROUGH THE SAN MARCOS PASS
VIA A NWS SPOTTER. GOLETA PROFILER DATA ALSO INDICATED A SHARP
INCREASE IN NORTHEAST WINDS ALOFT NEAR MIDNIGHT. AT 3 AM...N-S
GRADIENTS HAVE STARTED TO RELAX IN FAVOR OF NE-SW GRADIENTS AND WINDS
ACROSS SOUTHERN SANTA BARBARA COUNTY HAVE CORRESPONDINGLY WEAKENED.
WILL CANCEL THE WIND ADVISORY FOR SBA COUNTY SOUTH COAST AND
MOUNTAINS. WITH THE SHIFT IN GRADIENT ALIGNMENT..FOCUS NOW TURNS TO
NORTHEAST WINDS ACROSS VTU/LA COUNTIES.

FURTHER NORTH...EXTENSIVE STRATUS FORMATION IN THE CENTRAL VALLEY HAS
STACKED UP AGAINST THE NORTHERN MOUNTAIN SLOPES OF SLO/SBA
COUNTIES...EVEN SPILLING OVER THE LOWER ELEVATION SLO MOUNTAINS AND
OUT ONTO THE CENTRAL COAST. EXPECT STRATUS TO BURN OFF BY LATE
MORNING.

06Z MESOETA RUN INITIALIZED THE STRONGER WINDS OVER SBA COUNTY
WELL...BUT MAY HAVE UNDERESTIMATED WINDS ACROSS VTU AND LA COUNTY. AT
THIS TIME HOWEVER...ONLY SIMI VALLEY PROFILER INDICATING NEAR ADVISORY
LEVEL WINDS. ACROSS THE VTU/LA COUNTY MOUNTAINS...SUSTAINED WIND
SPEEDS NOT THAT HIGH...BUT WIND GUSTS ARE TOPPING 40 MPH...
DISCOUNTING WHITAKER PEAK. MODELS NOW INDICATING STRONGER UPPER LEVEL
SUPPORT ACROSS VTU/LA COUNTY LATER THIS MORNING...WITH 850MB WINDS
INCREASING AND TURNING EASTERLY. WILL KEEP WINDS JUST BELOW ADVISORY
LEVEL TODAY...BUT WILL ADJUST WORDING TO MAINTAIN WIND SPEEDS THROUGH
THE AFTERNOON.

AFTER AN IMPRESSIVE JUMP IN TEMPS YESTERDAY...EXPECT WARMUP TO
CONTINUE TODAY...WITH TEMPS IN THE LOW 80S POSSIBLE ACROSS THE LA
BASIN. TEMPS ON SATURDAY SHOULD DROP A FEW DEGREES AS OFFSHORE
GRADIENTS START TO RELAX...BUT REMAIN ABOVE NORMAL.

SUNDAY SEES A GRADIENT REVERSAL AS AN UPPER LOW DROPS SOUTHWARD AND
OVER SOCAL. FORECAST TRACK DRIVES THE LOW SOUTHWARD ALONG THE
COAST...AS OPPOSED TO STORMS EARLIER THIS SEASON WHICH APPROACHED
CALIFORNIA FROM THE EAST OVER WATER. THAT SAID...SYSTEM PROGGED TO
DROP IN ON SUNDAY WILL NOT HAVE THE CHANCE TO DRAW UP AS MUCH
SUBTROPICAL MOISTURE AS ITS PREDECESSORS HAD DONE. WITH 500 MB HEIGHTS
AND TEMPS EXPECTED TO DROP NEAR 550 DAM AND -22 DEGREES C
RESPECTIVELY...ANY PRECIP ON SUNDAY LOOKS TO BE MORE CONVECTIVE IN
NATURE. LOW POPS CHANCE ON SUNDAY BEST BET AT THIS TIME. TEMPS WILL
TAKE A DIVE REGARDLESS OF PRECIP SUNDAY AND MONDAY...AS HEIGHTS FALL
AND A COOL NORTH TO NORTHEASTERLY FLOW PATTERN SETS UP. OUTSIDE SHOT
AT SOME SNOW TO OUR MOUNTAINS ON MONDAY...AIR MASS WILL BE COOL ENOUGH
BUT WILDCARD IS THE AMOUNT OF MOISTURE PRESENT. MODELS HAVE BACKED OFF
ON THE TROUGH EARLIER PROGGED TO AFFECT THE AREA TUESDAY...SO CURRENT
DRY FORECAST IN THE EXTENDED WILL DO.
