SYNOPSIS
08/831 PM.
MUCH COOLER CONDITIONS ARE EXPECTED ON MONDAY AS A COASTAL EDDY
BRINGS SOUTHEAST FLOW TO THE AREA ALONG WITH COASTAL LOW CLOUDS
AND FOG. THE COOLING TREND WILL CONTINUE INTO TUESDAY, WITH
ANOTHER WARM AND EXPECTED TO START ON WEDNESDAY, LASTING THROUGH
AT LEAST FRIDAY AND POSSIBLY INTO NEXT WEEK.
SHORT TERM (SUN-WED)
08/155 PM.
OFFSHORE WINDS HAVE BEGUN TO SUBSIDE THIS AFTERNOON AND WILL ALLOW
THE WIND ADVISORY TO EXPIRE ON TIME AT 3 PM. BREEZY EAST WINDS
WILL TRANSITION SOUTH TO SOUTHEAST INTO MONDAY MORNING WITH A
SOUTHERLY SURGE EXPECTED TO BRING MORNING LOW CLOUDS AND FOG TO
THE COAST AND SIGNIFICANT COOLING TO ALL BUT THE FAR INTERIOR
AREAS. THE SAME LOW PRESSURE SYSTEM THAT HAS SUPPORTED THE
PROLONGED MODERATE TO STRONG SANTA ANA WINDS WILL SPIN BACK NORTH
INTO MONDAY AND MAY BRING MID TO HIGH LEVEL CLOUDS TO EASTERN LA
COUNTY WITH ANY RAIN LIKELY WELL TO OUR EAST.
AFTER DAYTIME HIGHS TODAY WELL INTO THE 80S AND LOW 90S IN WARMER
SPOTS, WE'LL SEE HIGHS ONLY IN THE 70S INTO MONDAY. AS SUCH, THE
HEAT ADVISORY WILL VERY LIKELY BE ALLOWED TO EXPIRE ON TIME THIS
EVENING. HOWEVER, WE ARE FAR FROM DONE WITH THE HEAT AS A
PROLONGED PERIOD OF WIDESPREAD MID 80S TO 90S WILL LIKELY BEGIN
THURSDAY AND MAY CONTINUE INTO NEXT WEEK. WE'LL SEE THE VERY FRONT
END OF THE TRENDS WEDNESDAY AS MODERATE OFFSHORE FLOW COMBINED
WITH A RAPIDLY BUILDING RIDGE NOSING IN FROM THE EAST TO BUMP
TEMPERATURES BACK INTO THE 80S IN WARMER COASTAL VALLEYS TO
INTERIOR. BREEZY NORTHWEST TO NORTHEAST WINDS ARE LIKELY BEGINNING
TUESDAY, POSSIBLY APPROACHING ADVISORY LEVELS BY WEDNESDAY
EVENING.
LONG TERM (THU-SUN)
08/157 PM.
MAX TEMPS WILL BE THE MAIN TALKING POINT OF THE THREE DAY STRETCH.
LOOK FOR 5 TO 10 DEGREES OF WARMING (ACROSS THE CSTS/VLYS) BOTH
WED AND THU WITH LITTLE CHANGE SLATED FOR FRIDAY. THU/FRI'S MAX
TEMPS WILL BE IN THE MID AND UPPER 70S AT THE BEACHES, THE 80S
ACROSS THE REST OF THE CSTS, AND 90S FOR THE VLYS. THESE MAX
TEMPS ARE 15 TO 25 DEGREES OVER NORMAL.
THE RIDGE WILL BREAK DOWN ON SATURDAY AND OFFSHORE FLOW FROM THE
NORTH WILL WEAKEN WHILE THE ONSHORE PUSH TO THE EAST WILL
INCREASE. LOOK FOR 3 TO 6 DEGREES OF COOLING WITH MAX TEMPS
REMAINING WELL ABOVE NORMAL WITH MODERATE HEAT IMPACTS POTENTIALLY
CONTINUING THROUGH THE WEEKEND AND EVEN INTO NEXT WEEK AWAY FROM
THE COAST.
BOTH AI-EC AND AI-GFS ARE DRY THROUGH THE 23RD OF THE MONTH.
