AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST SAT NOV 11 2006

.SYNOPSIS...A RIDGE NEAR THE ISLANDS WILL PRODUCE MUGGY WEATHER
THROUGH SUNDAY. STARTING SUNDAY NIGHT...A TROUGH WEST OF KAUAI WILL
DIG CLOSER TO THE ISLANDS. WINDS OVER KAUAI AND OAHU WILL SHIFT TO
SOUTH AND THE CHANCE OF SHOWERS WILL INCREASE OVER THE WESTERN
ISLANDS. A FRONT WILL MOVE OVER KAUAI ON TUESDAY AND STALL AS TRADE
WINDS BUILD BACK OVER THE ISLANDS. THE STALLED FRONT WILL KEEP KAUAI
RATHER SHOWERY MOST OF NEXT WEEK.

&&

.DISCUSSION...WINDS OVER MAUNA KEA AND MAUNA LOA MAY APPROACH THE
ADVISORY THRESHOLD BY MORNING SO WE WILL BE WATCHING CLOSELY TO SEE
IF AN ADVISORY IS NEEDED OVERNIGHT. OTHERWISE...THE CURRENT FORECAST
PACKAGE LOOKS GOOD.

&&

.PREV DISCUSSION 400 PM...SOUTHEASTERLY WINDS OVER THE WESTERN END
OF THE STATE WILL CONTINUE TO SLOWLY SHIFT SOUTHERLY ON SUNDAY...
WHILE A WEAK UPPER LOW MAY ENHANCE SHOWERS ON THE BIG ISLAND. WITH
THE BIG ISLAND ACTING AS A PARTIAL BLOCK TO THE SOUTHEASTERLY
FLOW...THE SMALLER ISLANDS WILL EXPERIENCE LIGHT WINDS...LEADING TO
LOCAL LAND AND SEA BREEZES...AND INCREASINGLY HUMID CONDITIONS ON
SUNDAY. SEA BREEZES OVER THE SMALLER ISLANDS WILL RESULT IN CLOUDS
AND SHOWERS OVER INTERIOR SECTIONS ON SUNDAY AFTERNOON...BUT WEAK
RIDGING ALOFT WILL KEEP RAINFALL RATHER LIGHT THROUGH TOMORROW FOR
THE WESTERN ISLANDS.

RAINFALL WILL BE POTENTIALLY HEAVIER ON THE BIG ISLAND LATE TONIGHT
AND SUNDAY AS A WEAK UPPER LOW MOVES OVER FROM THE SOUTHEAST. SO
FAR...THIS FEATURE IS ENHANCING SHOWERS WITHIN THE TRADE WIND FLOW
JUST SOUTH OF THE BIG ISLAND...BUT AS IT MOVES OVERHEAD ON
SUNDAY...THE COMBINATION OF INSTABILITY AND DAYTIME HEATING MAY
TRIGGER LOCALLY HEAVY SHOWERS. WITH 500 MB TEMPS OF -9C EXPECTED...A
SLIGHT CHANCE OF THUNDERSTORMS WAS ADDED FOR THE BIG ISLAND SLOPES
FOR TOMORROW AFTERNOON.

THE TROUGH SEVERAL HUNDRED MILES WEST OF KAUAI WILL BRING WET AND
UNSETTLED WEATHER TO THE WESTERN END OF THE STATE EARLY NEXT WEEK.
AN UPPER TROUGH NOW APPROACHING THE DATELINE WILL DIVE SOUTHEASTWARD
TOMORROW AND DEVELOP A FRONT ALONG THE TROUGH. THE FRONT AND ITS
ASSOCIATED SHOWERS WILL REACH KAUAI LATE MONDAY NIGHT OR TUESDAY...
BUT CONVERGENCE BANDS IN THE SOUTHERLY AND SOUTHWESTERLY FLOW AHEAD
OF THE FRONT COULD BRING SHOWERS TO THE SMALLER ISLANDS AS EARLY AS
SUNDAY NIGHT. FORECAST MODELS STALL THE FRONT AND MOST OF ITS
ASSOCIATED RAINFALL NEAR OR OVER KAUAI ON TUESDAY...THEN BEGIN TO
LIFT THE FRONT BACK TO THE NORTH LATE WEDNESDAY.

THE LONG RANGE PICTURE IS STILL A BIT UNCERTAIN. LIGHT EAST WINDS
AND DRIER CONDITIONS LOOK TO MAKE A RETURN ON THURSDAY. FORECAST
MODELS HINT AT LOW LEVEL TROUGHING IN SOME FORM REDEVELOPING TO THE
WEST OF THE STATE...WHICH MAY CAUSE WINDS TO VEER OUT OF THE
SOUTHEAST AGAIN TO END THE WORK WEEK.

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