UPPER RIDGE OFF THE COAST WILL STRENGTHEN OVER REGION DURING THE
NEXT 2 DAYS...WITH HEIGHTS OF 590 DM EXPECTED DURING PERIOD. THE
UNUSUALLY STRONG HIGH PRESSURE CENTER COMBINED WITH INCREASING
OFFSHORE FLOW WILL BRING SOME VERY WARM AND DRY CONDITIONS TO 
LOW ELEVATION LOCATIONS. NORTHEAST WINDS ARE EXPECTED TO INCREASE
LATER TONIGHT AND TUESDAY BELOW PASSES AND CANYONS...AND PERHAPS
BE A LITTLE STRONGER TUESDAY NIGHT INTO WEDNESDAY.

MODERATE OFFSHORE GRADIENTS ALREADY IN PLACE THIS EVENING...AS
EVIDENT BY -4.8 MB OFFSHORE GRADIENT BETWEEN LAX AND DAGGETT. 
THIS OFFSHORE GRADIENT EXPECTED TO PEAK BETWEEN -6 AND -7 MB
BOTH TUESDAY AND WEDNESDAY MORNINGS. UPPER LEVEL SUPPORT RATHER
MINIMAL AT THE MOMENT...BUT LOW LEVEL WINDS UP TO 850 MB EXPECTED
TO INCREASE LATER TONIGHT AND TUESDAY. LOW LEVEL WINDS AND SUBSIDENCE
INCREASE EVEN FURTHER TUESDAY NIGHT INTO WEDNESDAY. 

WIND ADVISORIES ALREADY POSTED FOR VTU COUNTY VALLEYS AND SANTA
CLARITA VALLEY...AND WILL ADD VENTURA/LOS ANGELES COUNTY MOUNTAINS
(INCLUDING SANTA MONICA RANGE) TO ADVISORY AREA...SINCE FREQUENT GUSTS
OVER 45 MPH ARE EXPECTED LATER TONIGHT THROUGH WEDNESDAY. WINDS MAY
DIMINISH SOME LATE TUESDAY AFTERNOON AND EVENING...BUT WILL KEEP
ADVISORY GOING THROUGH WEDNESDAY...RATHER THAN REISSUING ANOTHER
ADVISORY TOMORROW EVENING. 

OTHER BIG STORY OVER NEXT COUPLE OF DAYS WILL BE VERY WARM
TEMPERATURES. HIGH TEMPERATURES SOARED INTO THE LOWER TO MID
80S IN MANY LOCATIONS TODAY. WITH OFFSHORE GRADIENTS AND BOUNDARY
LAYER TEMPERATURES INCREASING THROUGH WEDNESDAY...LOOK FOR WARMING
TREND TO CONTINUE. WOULD NOT BE SURPRISED TO SEE A FEW LOCATIONS
EVEN BREAK 90 DEGREES (EVEN NEAR THE COAST) NEXT COUPLE OF DAYS.
AS A RESULT...MAY SEE A FEW RECORDS BROKEN EACH DAY...AND WILL HEADLINE
ZONES FOR NEAR RECORD HIGHS IN EVENING UPDATE. 

WARM CONDITIONS EXPECTED TO CONTINUE INTO THURSDAY...THEN A GRADUAL
COOLING TREND INTO THE WEEKEND...ESPECIALLY ALONG THE COAST.
