945 AM HST MON SEP 6 2010

.SYNOPSIS...
LIGHT TO MODERATE TRADE WINDS WILL CONTINUE ACROSS HAWAII THROUGH
THE WEEK...AS A HIGH PRESSURE SYSTEM REMAINS LOCATED FAR NORTH OF
THE STATE. SHOWERS WILL FAVOR WINDWARD AND MOUNTAIN AREAS.

&&

.DISCUSSION...
SHOWERY CONDITIONS CONTINUED EARLY THIS MORNING ON WINDWARD AND
MOUNTAIN AREAS.  ISOLATED SHOWERS DRIFTED LEEWARD...BUT MOST OF THE
RAINFALL WAS MEASURED IN THE WINDWARD RAIN GAGES. ON KAUAI...80
PERCENT OF WINDWARD GAGES HAD MEASURABLE RAIN IN THE PAST 12 HOURS
WITH MOUNT WAIALEALE THE WINNER AT 0.46 OF AN INCH. ON LEEWARD
KAUAI...60 PERCENT OF GAGES HAD MEASURABLE RAINFALL WITH 0.19 AT
OMAO FOR THE MOST. FOR OAHU...70 PERCENT WINDWARD AND MAUKA GAGES
HAD MEASURABLE RAINFALL IN THE PAST 12 HOURS WITH 0.25 AT WILSON
TUNNEL THE WINNER...AND ONLY 4 LEEWARD STATIONS HAD MEASURABLE WITH
0.28 THE MOST AT HONOULIULI. MAUI HAD MUCH LESS RAIN ACCUMULATION
AT 40 PERCENT OF WINDWARD GAGES AND NONE MEASURED LEEWARD.  THE BIG
ISLAND HAD 100 PERCENT OF WINDWARD GAGES AND A HANDFUL OF LEEWARD
GAGES REPORTING MEASURABLE RAINFALL. THE HIGHEST 12 HOUR TOTAL WAS
.30 OF AN INCH AT UPCOUNTRY HILO GAGES...PIIHONUA AND WAIAKEA UKA.

THE SHORT TERM OUTLOOK FOR THE REST OF THE MORNING AND EARLY
AFTERNOON LOOKS A BIT DRIER FOR MOST AREAS AS THE NEXT BATCH OF
UPSTREAM MOISTURE IS STILL FAR TO THE EAST...STILL MAY BEGIN TO SEE
THE SHOWERS START TO INCREASE AS EARLY AS LATE THIS AFTERNOON AND
EVENING ON WINDWARD AND MOUNTAIN AREAS.  EXPECT THE SHOWERS TO FILL
BACK IN OVERNIGHT TONIGHT ALONG MOST WINDWARD AND MAUKA AREAS AS THE
CLOUD TOPS COOL AND THE INVERSION DEEPENS AS DEPICTED BY THE LATEST
MODEL DATA.

FOR THE REST OF THE WEEK...ON THE LARGE SCALE...THE SURFACE RIDGE
FAR NORTH OF THE STATE REMAINS IN ITS WEAKENED STATE MUCH OF THE
WEEK. AT UPPER LEVELS THE ISLANDS STAY UNDER THE INFLUENCE OF A
RIDGE AS AN UPPER LEVEL TROUGH RIDES WELL NORTH OF THE STATE. MODELS
SUGGEST DRIER AND MORE STABLE AIR FILTERING INTO THE STATE FROM THE
EAST LATE TUESDAY THROUGH THURSDAY. THIS WILL LEAD TO LESS IN THE
WAY OF SHOWER ACTIVITY IN GENERAL. THEN ANOTHER BATCH OF MOISTURE
MAY WORK ITS WAY IN FRIDAY AND SATURDAY. THE TRADES WILL REMAIN
LIGHT TO MODERATE THROUGH THE PERIOD.

&&

.MARINE...
WINDS AND SEAS OVER THE SURROUNDING COASTAL WATERS WILL REMAIN BELOW
SMALL CRAFT ADVISORY THRESHOLDS THROUGH THE WEEK. THE SURF WILL
REMAIN SMALL AS WELL.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
NONE.
