830 PM HST SAT JUN 30 2007

.SYNOPSIS...MODERATE TRADES WILL PERSIST INTO THE FIRST HALF OF THE
COMING WEEK. RAINFALL WILL BE LIGHT...AND LIMITED MAINLY TO WINDWARD
AND MOUNTAIN AREAS...THOUGH SOME STILL WILL FALL OVER LEE SLOPES IN
THE AFTERNOON.

&&

.DISCUSSION...MODERATE TRADE WINDS PERSISTED OVER THE MAIN HAWAIIAN
ISLANDS...AND THOUGH THEY HAD DIMINISHED FROM EARLIER IN THE WEEK...
GUIDANCE SUGGESTED THAT THEY HAD BOTTOMED OUT FOR THE TIME BEING.
RAIN ACCUMULATION HAD DROPPED OFF CONSIDERABLY DURING THE DAY...
DESPITE HIGH PRECIPITABLE WATER VALUES NEAR THE BIG ISLAND. THE
RELATIVELY LOW INVERSION HEIGHTS EVIDENT IN BOTH LOCAL SOUNDINGS NO
DOUBT PLAYED A PART...THOUGH GIVEN THE WEAK RIDGING ALOFT THE SOURCE
OF THE RESPONSIBLE SUBSIDENCE WAS NOT ENTIRELY CLEAR.

GUIDANCE AGREES FAIRLY WELL THAT THE WEAK RIDGE ALOFT WILL ERODE
FURTHER...LEAVING A COL IN ITS PLACE BY MONDAY. MUCH LOWER HEIGHTS
TO THE NORTH OF THE ISLANDS WILL WEAKEN THE SUBTROPICAL RIDGE AT THE
SURFACE TOO...SO THE TRADES ARE EXPECTED TO REMAIN ON THE SLOW SIDE
OF AVERAGE...LEADING TO DIMINISHED OROGRAPHIC FORCING...AND THUS
CONTINUED MODERATELY DRY CONDITIONS.

PAST THE MIDDLE OF NEXT WEEK...THE SOLUTIONS PREDICT THAT RIDGING
ALOFT WILL RETURN ONLY SLOWLY. MOST MODELS MAINTAIN A SHALLOW BUT
PERSISTENT UPPER TROUGH OVER THE ISLANDS UNTIL THURSDAY OR FRIDAY...
WHEN HEIGHTS WILL REBOUND AGAIN...ALLOWING THE SUBTROPICAL RIDGE TO
REBUILD AT THE SURFACE TOO. STRONGER TRADES WILL PRODUCE MORE
WIDESPREAD TRADE-WIND SHOWERS...AND THE MOIST AIRMASS UPWIND FINALLY
MAY CONTRIBUTE AS WELL. THUS...CONDITIONS WILL TREND CLOSER TO
CLIMATOLOGY OVER THE SECOND HALF OF THE COMING WEEK.

&&

.MARINE...A SOUTH SWELL IS FORECAST TO CONTINUE PRODUCING SURF JUST
OVER THE ADVISORY LEVEL ALONG SOUTH-FACING SHORES THROUGH SUNDAY
AFTERNOON.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...

THE HIGH SURF ADVISORY CONTINUES FOR SOUTH-FACING SHORES OF ALL
ISLANDS THROUGH 6 PM HST SUNDAY.
