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

INTERIOR. BREEZY NORTHWEST TO NORTHEAST WINDS ARE LIKELY BEGINNING
TUESDAY, POSSIBLY APPROACHING ADVISORY LEVELS BY WEDNESDAY
EVENING.

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
