DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
THIS MORNING...SHOWERS HAVE ENDED BUT WE REMAIN UNDER THE INFLUENCE
OF BROAD TROUGHING ALOFT. A WEAK SHORTWAVE TROUGH EMBEDDED IN THE
MEAN CYCLONIC FLOW ALOFT WILL BRING WIDESPREAD MID AND HIGH
CLOUDS OVER A SCATTERED LAYER OF LOW CLOUDS THAT IS MOSTLY PUSHED
UP AGAINST THE COASTAL FOOTHILLS. THE WESTERLY WINDS CONTINUE TO
WEAKEN AND THE WINDIEST LOCATIONS HAVE REPORTED STRONGEST GUSTS OF
35-45 MPH.
TEMPERATURES WILL BE ABOUT 5-15 DEGREES LOWER THAN NORMAL TODAY;
ONLY A FEW PLACES AT LOWER ELEVATIONS MAY ACHIEVE 60+ DEGREES,
WEAK HIGH PRESSURE ALOFT DEVELOPS FOR THIS WEEKEND, AND THERE IS
ALSO AN OFFSHORE PRESSURE GRADIENT THAT DEVELOPS TONIGHT AND LASTS
THROUGH SATURDAY. THAT WILL PRODUCE AREAS OF GUSTY EASTERLY WINDS
THROUGH THE PENINSULAR MOUNTAINS LOCALLY INTO INLAND VALLEYS.
THAT WILL BOOST THE WARMING TREND WEST OF THE MOUNTAINS. THE
OFFSHORE FLOW WEAKENS A LITTLE ON SUNDAY, BUT THE WARMING TREND
CONTINUES INTO MONDAY. HIGH TEMPERATURES WILL BE IN THE 60S
SATURDAY, 70S SUNDAY, AND A FEW SPOTS SHOULD HIT 80 DEGREES
MONDAY. SKIES WILL HAVE PERIODS OF HIGH CLOUDS, BUT THE SUN WILL
SHINE THROUGH MOST OF THE TIME. OUR UPPER RIDGE OF HIGH PRESSURE
OVER CALIFORNIA WILL AMPLIFY SOME NEXT WEEK. A PLUME OF MOISTURE
TRIES TO APPROACH SOCAL NEXT WEDNESDAY, BUT NOW NEARLY ALL MODEL
GUIDANCE STEERS THAT MOISTURE INTO NORTHERN AND CENTRAL
CALIFORNIA. CONFIDENCE IS NEARLY 100% THAT SOCAL WILL STAY DRY
THROUGH AT LEAST FRIDAY. IT WILL BE A LITTLE COOLER TUESDAY
THROUGH THURSDAY AS WEAK ONSHORE FLOW RETURNS, BUT STILL WELL
ABOVE NORMAL. THE RIDGE APPEARS TO AMPLIFY LATER NEXT WEEK, WHICH
IF IT DOES, COULD PRODUCE WIDESPREAD TEMPERATURES IN THE 80S IN
THE VALLEYS, AND LOWER 90S IN THE LOW DESERT ON FRIDAY.
AVIATION
201800Z...ANY LINGERING RAIN SHOWERS HAVE FULLY MOVED OUT OF THE
AREA, AND VFR CONDITIONS WILL PREVAIL THROUGH THE TAF PERIOD. ASIDE
FROM FEW-SCT CU BASED AROUND 4000-6000FT MSL AND SCT-BKN HIGH CLOUDS
NEAR 20,000FT, MOSTLY CLEAR CONDITIONS EXPECTED. WINDS HAVE LARGELY
DECREASED AS WELL, WITH WEAK OFFSHORE WINDS EXPECTED IN MAJOR
MOUNTAIN PASSES SATURDAY AFTERNOON.
MARINE
WINDS OVER THE WATERS CONTINUE TO WANE TODAY, WITH GUSTS GENERALLY
15 KTS OR LESS EXPECTED THIS AFTERNOON. SEAS ARE DECREASING AS WELL,
WITH THE SMALL CRAFT ADVISORY ALLOWED TO EXPIRE. NO MARINE HAZARDS
ARE EXPECTED THROUGH TUESDAY.
BEACHES
ELEVATED SWELL CONTINUES TO WANE TODAY, WITH SURF EXPECTED TO REMAIN
BELOW 7 FEET. THUS, THE HIGH SURF ADVISORY THAT PREVIOUSLY EXTENDED
INTO THIS EVENING HAS BEEN CANCELLED. HIGH SURF OF 3 TO 5 FEET
REMAINS POSSIBLE TODAY, WHICH CAN STILL LEAD TO AREAS OF STRONG RIP
CURRENTS.
