SYNOPSIS
09/252 PM.
COOL CONDITIONS WILL CONTINUE THROUGH TUESDAY. ANOTHER WARM UP
EXPECTED TO START ON WEDNESDAY, LIKELY LASTING WELL INTO NEXT WEEK.
SHORT TERM (MON-THU)
09/249 PM.
AFTER A HUGE COOL DOWN TODAY SOME AREAS WILL SEE A BIT MORE
COOLING THANKS TO STRONG ONSHORE TRENDS AND A LIKELY RETURN OF
WIDESPREAD NIGHT TO MORNING LOW CLOUDS AND FOG TO COASTS AND MOST
COASTAL VALLEYS THIS EVENING THROUGH WEDNESDAY MORNING.
MODERATE OFFSHORE TRENDS TUESDAY EVENING THROUGH THURSDAY MORNING
WILL SUPPORT GUSTY NORTHWEST TO NORTHWEST WINDS THROUGH WEDNESDAY,
LIKELY BECOMING NORTHEAST INTO THURSDAY. ADVISORY LEVEL WINDS ARE
EXPECTED TO MAINLY BE FOCUSED ACROSS INTERIOR MOUNTAINS TUESDAY
EVENING THROUGH WEDNESDAY MORNING AND WE HAVE ISSUED A WIND
ADVISORY ACCORDINGLY. THERE IS A 30-50 PERCENT CHANCE OF ADVISORY
LEVEL WINDS CONTINUING INTO THURSDAY EXTENDING INTO COASTAL AND
COASTAL VALLEY AREAS PRONE TO SANTA ANA WINDS.
THE OFFSHORE TRENDS AND A SIGNIFICANT RIDGE BUILDING OVERHEAD WILL
SUPPORT 5-15 DEGREES OF WARMING WEDNESDAY AND INTO THURSDAY WITH A
50-70 PERCENT CHANCE OF MODERATE, ADVISORY LEVEL HEAT. THURSDAY
MAY ALSO MARK A PROLONGED PERIOD OF DAYTIME HIGHS IN THE 90S AWAY
FROM THE COAST AND ESPECIALLY FOR THE COASTAL VALLEYS.
LONG TERM (FRI-MON)
09/249 PM.
THE OFFSHORE FLOW WEAKENS SOME ON FRIDAY - ENOUGH TO LOWER THE
MORNING OFFSHORE WINDS SOME, BUT NOT ENOUGH TO AFFECT TEMPS, WHICH
WILL END UP VERY CLOSE TO THURSDAY'S VERY WARM VALUES.
OVER THE WEEKEND THE RIDGE WILL BREAK DOWN WHILE THE OFFSHORE
FLOW FROM THE NORTH WILL WEAKEN AND THE ONSHORE PUSH TO THE EAST
WILL INCREASE. LOOK FOR A COUPLE OF DEGREES OF COOLING EACH DAY WITH
MAX TEMPS REMAINING WELL ABOVE NORMAL WITH MODERATE HEAT IMPACTS
POTENTIALLY CONTINUING THROUGH THE WEEKEND AND EVEN WELL INTO
NEXT WEEK AWAY FROM THE COAST. IN FACT ANOTHER MORE SIGNIFICANT
ROUND OF HEAT IS POSSIBLE BY THE MIDDLE PART OF NEXT WEEK.
NO RAIN ON THE HORIZON THROUGH AT LEAST 10 DAYS.
