SHORT TERM...STRONG OFFSHORE GRADIENTS CONTINUE THIS MORNING, BUT UPPER SUPPORT IS WEAKER. HARD TO FIND ADVISORY LEVEL WINDS IN THE OBS THIS MORNING BUT THERE WAS JUST ENOUGH TO KEEP THE ADVISORIES GOING IN ALL AREAS EXCEPT THE SBA MOUNTAINS. WE MAY STILL GET A LATE MORNING
SURGE IN THE WINDS SO I WASN'T CONFIDENT ENOUGH TO DROP THE ADVISORIES EVERYWHERE. WINDS SHOULD DROP BELOW ADVISORY LEVELS LATER THIS AFTERNOON WITH JUST A MINOR PICK UP IN THE WINDS AGAIN MONDAY MORNING. AS A RESULT, I DO NOT EXPECT ADVISORIES TO BE EXTENDED BEYOND 230 THIS AFTERNOON.

SOUNDINGS SHOW A LITTLE WARMING, ESPECIALLY AT HIGHER ELEVATIONS. THIS IS REFLECTED NICELY IN THE TEMPERATURE TRENDS THIS MORNING WITH ALL MOUNTAIN AREAS 5 TO 10 DEGREES WARMER THAN AT THE SAME TIME SAT. WEST OF THE MOUNTAINS, TEMPERATURES SHOULD GET A LITTLE BOOST FROM THE OFFSHORE FLOW SO HIGHS SHOULD BE ABOUT 5 DEGREES WARMER THAN SAT. ON THE FLIP SIDE OF THIS, OVERNIGHT LOWS WILL STILL BE QUITE CHILLY TONIGHT WITH INLAND SLO COUNTY AND THE ANTELOPE VALLEY DIPPING INTO THE LOWER 20S AGAIN. SINCE WE'VE HAD A FEW SUB-FREEZING MORNINGS IN THOSE AREAS THIS SEASON ALREADY WE WON'T BE ISSUING MORE ADVISORIES OR WARNINGS. THE COASTAL AREAS OF SLO/SBA COUNTIES, INCLUDING THE CITY OF SANTA BARBARA WILL DROP TO AROUND FREEZING AGAIN MONDAY MORNING.

SHORT TERM...WINDS CONTINUE IN THE MOUNTAINS THIS EVENING...WITH SOME VALLEY LOCATIONS ALSO HAVING GUSTY WINDS. WITH THE NORTHEAST FLOW INCREASING OVERNIGHT MORE WIDESPREAD GUSTY WINDS BELOW PASSES AND CANYONS CAN BE EXPECTED OVER THE MOUNTAINS AND L.A./VTU VALLEYS. WIND ADVISORIES WILL CONTINUE IN THESE AREAS THRU EARLY SUN AFTERNOON. IN ADDITION...A COOL AND VERY DRY AIRMASS OVER THE REGION WILL ALLOW FOR EXCELLENT RADIATIONAL COOLING WITH INTERIOR SLO/SBA COUNTIES AND ANTELOPE VALLEY EXPECTED TO HAVE WIDESPREAD LOW TEMPS WELL DOWN INTO THE 20S. FROSTY CONDITIONS ARE ALSO EXPECTED LATE TONIGHT ALONG THE CENTRAL COAST. FREEZE WARNINGS AND FROST ADVISORIES ARE IN EFFECT FOR THESE AREAS. FOR DETAILS ON ALL THE WIND AND COLD TEMPERATURE ADVISORIES PLEASE SEE THE PRODUCT LAXNPWLOX.

WEAK UPPER RIDGE WILL BUILD OVER SOCAL ON SUN...THEN A WEAK UPPER TROF WILL MOVE THRU CA ON MON. A BROAD NW FLOW ALOFT WILL PREVAIL FOR TUE. THE OFFSHORE FLOW WILL PERSIST BUT BE WEAKER SUN NITE INTO MON. DRY BUT GENERALLY COOL WEATHER CAN BE EXPECTED ACROSS THE DISTRICT THRU TUE.
