STORM STILL GENERATING SOME CLOUDS ACROSS INTERIOR SLO/SBA COUNTIES
AND IN THE MTNS BUT OTHERWISE GENERALLY CLEAR SKIES ACROSS THE AREA.
TEMPS WARMED JUST ABOUT EVERYWHERE TODAY AND EXPECT THAT TREND TO
CONTINUE AT LEAST THROUGH WED AS HIGH PRESSURE ALOFT AND OFFSHORE
FLOW STRENGTHENS. MODELS HAVE CHANGED VERY LITTLE IN THE LAST FEW
DAYS WITH REGARD TO THE STRENGTH OF BOTH OF THOSE FEATURES, THUS
WE'RE STILL LOOKING AT A SUB-ADVISORY LEVEL OFFSHORE WIND EVENT,
PEAKING WEDNESDAY MORNING. SKIES EXPECTED TO REMAIN CLEAR (AFTER
TODAY'S CLOUDS DISSIPATE), THOUGH WE WILL SEE SOME HIGH CLOUDS
MONDAY FROM A SYSTEM MOVING OVER THE RIDGE INTO THE PAC NW. HIGHS
EXPECTED TO WARM 5-8 DEGREES EACH DAY THROUGH WEDNESDAY, BRINGING
MOST COAST/VALLEY AREAS WELL INTO THE 80S AND EVEN SOME ISOLATED
LOWER 90S POSSIBLE.

.LONG TERM (THU-SUN)...WARM PATTERN TO CONTINUE RIGHT INTO THE
WEEKEND, THOUGH WEAKING OFFSHORE GRADIENTS SHOULD LEAD TO AT LEAST A
FEW DEGREES OF COOLING FOR LOWER ELEVATIONS. STILL WELL ABOVE NORMAL
THROUGH SUNDAY.

&&

.FIRE WEATHER...02/330 PM
A PROLONGED PERIOD OF WEAK TO MODERATE OFFSHORE WINDS AND LOW
HUMIDITIES WILL BRING AN EXTENDED PERIOD OF ELEVATED FIRE DANGER TO
SOUTHERN CALIFORNIA THIS WEEK. WINDS GUSTS WILL GENERALLY RANGE
BETWEEN 30 AND 40 MPH THIS WEEK ACROSS WIND PRONE PASSES AND CANYONS
OF LOS ANGELES AND VENTURA COUNTIES...BUT COULD REACH AS HIGH AS 45
MPH ACROSS FAVORED MOUNTAIN LOCATIONS ON WEDNESDAY (PEAK OF EVENT).
MEANWHILE A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE AREA FROM THE
WEST...BRINGING A WARMING TREND ALONG WITH DRYING CONDITIONS. THE
WARMEST DAYS ARE EXPECTED TO BE WEDNESDAY THROUGH THURSDAY WITH
HOTTEST LOCATIONS CLIMBING TO AROUND 90 DEGREES. HUMIDITIES WILL
GENERALLY LOWER INTO THE TEENS EACH DAY WITH AREAS OF SINGLE DIGIT
READINGS TUESDAY THROUGH FRIDAY. THERE WILL LIKELY BE BRIEF CRITICAL
