HIGH PRESSURE WILL THEN BRING A WARMING TREND LATE IN THE WEEK...FOLLOWED BY A COOLING TREND INTO EARLY NEXT WEEK. && .SHORT TERM (TODAY-FRI)...WILL ISSUE AN UPDATE THIS EVENING. THE GUSTY NORTHWEST WINDS ALONG THE CENTRAL COAST WERE DIMINISHING AND WILL DIMINISH BELOW ADVISORY THRESHOLDS BY 9PM. OTHERWISE THE GUSTY NORTHWEST WINDS ALONG THE FOOTHILLS OF THE SOUTH COAST AND HIGH COUNTRY IN SANTA BARBARA COUNTY WILL SHIFT TO NORTH AND LIKELY REMAIN ABOVE ADVISORY THRESHOLDS OVERNIGHT. A SIMILAR SCENARIO IS EXPECTED OVER VENTURA AND LOS ANGELES COUNTIES WHERE THE WINDS DIMINISH IN THE LOWER ELEVATIONS AS WELL AS THE DESERT AND REMAIN RELATIVELY STRONG OVER THE HIGHER ELEVATIONS.
