***FROM PREVIOUS DISCUSSION***
YESTERDAY'S RIDGE WILL FLATTEN OUT TODAY. HGTS WILL FALL TO ABOUT
590 DAM. ONSHORE FLOW WILL INCREASE AS WELL. THE EDDY, HOWEVER, IS
ABSENT AND THIS WILL LIMIT THE AMOUNT OF LOW CLOUDS INTO THE
VALLEYS. MAX TEMPS WILL BE SIMILAR TO YDY'S EXCEPT FOR SOME
WARMING IN THE VLYS DUE TO THE LACK OF MARINE LAYER. IT WILL BE A
LITTLE DRIER AS DRIER AIR MOVES IN FROM THE WEST. A LOW LEVEL HEAT
ADVISORY REMAINS IN EFFECT FOR THE LA VLYS AND THE LA INTERIOR
CSTL AREAS.
WEAK CYCLONIC FLOW MOVES INTO THE STATE ON THURSDAY AND WILL BE
ACCOMPANIED BY AN INCREASE IN ONSHORE FLOW BOTH TO THE NORTH AND
EAST. LOOK FOR AND INCREASE IN THE MORNING LOW CLOUDS AND FOR THE
VLYS. THE LOW CLOUDS WILL CLEAR SLOWLY AND SOME BEACHES MAY REMAIN
CLOUDY FOR MOST OF THE AFTERNOON. THE STRONG ONSHORE PUSH TO THE
EAST WILL GENERATE GUSTY AFTERNOON WINDS IN THE ANTELOPE VLY IN
THE AFTERNOON. MAX TEMPS WILL BE SIMILAR TO TODAY'S, PERHAPS A
LITTLE COOLER IN THE VLYS.
FRIDAY WILL SEE A SUBSTANTIAL INCREASE IN CYCLONIC FLOW AND THERE
WILL BE STRONG ONSHORE FLOW. LOOK FOR PLENTY OF LOW CLOUDS ACROSS
THE CSTS/VLYS WITH SLOW CLEARING AND NO CLEARING FOR MANY BEACH
AREAS. THE ONSHORE PUSH MAY WELL BRING ADVISORY LEVEL WINDS TO THE
WESTERN ANTELOPE VLY AND ITS FOOTHILLS IN THE AFTERNOON AND EARLY
EVENING.
SUNDOWNER POTENTIAL INCREASES ON FRIDAY, WITH LIKELY ADVISORY
LEVEL WINDS ESPECIALLY ON SATURDAY. MOST MAX TEMPS WILL COOL 2 TO
4 DEGREES AND MAX TEMPS WILL END UP A FEW DEGREES BLO NORMAL.
GUSTY WINDS WILL DEVELOP ACROSS SW SBA COUNTY IN THE EVENING AND
ADVISORY LEVEL GUSTS LOOK LIKELY FOR THE WESTERN PORTION OF THE
SBA SOUTH COAST.
LONG TERM (SAT-TUE)
24/236 AM.
JUNE GLOOM WILL BE BACK WITH A VENGEANCE DURING THE XTND PERIOD.
AN UNSEASONABLY COLD UPPER LOW WILL MOVE INTO THE THE PACNW AND
SLOWLY MOVE THROUGH. A TROF ASSOCIATED WITH THE UPPER LOW WILL BE
DRAPED OVER CA FOR THE 4 DAY PERIOD. HGTS WILL FALL TO AROUND 584
DAM. STRONG ONSHORE FLOW WILL CONTINUE TO THE EAST. WHILE THERE
WILL BE MODERATE ONSHORE FLOW TO THE NORTH IN THE AFTERNOON IT
WILL BE MUCH WEAKER IN THE MORNINGS. LOOK FOR PLENTY OF NIGHT
THROUGH MORNING LOW CLOUDS ACROSS THE CSTS/VLYS EVERY DAY.
CLEARING WILL BE ON THE SLOW SIDE AND A FEW BEACHES WILL REMAIN
CLOUDY IN THE AFTERNOON. PORTIONS OF THE SBA SOUTH CST MAY BE THE
EXCEPTION AS LOCAL NORTH FLOW MAY KEEP THE LOW CLOUDS AWAY.
LOOK FOR A BIG COOL DOWN ON SATURDAY FOLLOWED BY MINIMAL CHANGES
SUN THRU TUE. MAX TEMPS WILL MOSTLY BE IN THE 70S ACROSS THE
CSTS/VLYS (MID TO UPPER 60S AT THE BEACHES) AND ONLY LOWER TO MID
80S FOR THE INLAND AREAS. THESE MAX TEMPS ARE 3 TO 5 DEGREES
COOLER THAN NORMAL AT THE CSTS AND 5 TO 10 LOCALLY 12 BELOW NORMAL
ACROSS THE VLYS AND INLAND AREAS.
