AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST FRI FEB 2 2007

.SYNOPSIS...CLOUD COVER ACROSS MAUI COUNTY AND THE BIG ISLAND
ASSOCIATED WITH A COLD FRONT WILL MOVE EAST OF THE STATE LATER
TODAY. THE NEXT FEW NIGHTS WILL BE A BIT CHILLY AS DRIER AND COOLER
AIR MOVES IN WITH THE CLEARER SKIES. ANOTHER FRONT WILL REACH THE
ISLANDS WEDNESDAY OR THURSDAY.

&&

.DISCUSSION...THE LEADING EDGE OF THE WIND SHIFT LINE ASSOCIATED
WITH THE COLD FRONT HAS MOVED SOUTHEAST OF THE BIG ISLAND THIS
MORNING...BUT A RESIDUAL BAND OF CLOUDS AND SHOWERS REMAINS.
PORTIONS OF THE BIG ISLAND AND MUCH OF MAUI COUNTY REMAIN AFFECTED
BY BROKEN TO OVERCAST LOW CLOUDS...BUT THESE WILL PASS SOUTHEAST OF
THE STATE THROUGH TODAY AND TONIGHT AS COOLER AND DRIER AIR MOVES IN
FROM THE NORTHWEST. LOWS THIS MORNING IN THE UPPER 50S AND LOW 60S
ACROSS THE SMALLER ISLANDS CONTRAST WITH THE 70S REPORTED ON THE
BIG ISLAND...WHERE CLEARING AND COOLING HAVE YET TO OCCUR. AS
CLEARING CONTINUES TODAY AND BREEZY NORTHERLIES MOVE IN LATER TODAY
AND TONIGHT...ADDITIONAL COOLING IS EXPECTED AND WE MAY APPROACH A
RECORD LOW OR TWO.

THE SURFACE FRONT MAY BE ABOUT TO LEAVE THE STATE...BUT THE
SUPPORTING UPPER TROUGH PERSISTS TO OUR NORTH. UPPER LEVEL WINDS
ALONG THE SOUTHEASTERN FLANK OF THIS TROUGH ARE QUITE
STRONG...KEEPING WIND SPEEDS ABOVE WARNING LEVEL ACROSS HALEAKALA ON
MAUI AND THE HIGHEST SUMMITS ON THE BIG ISLAND. WINDS SHOULD EASE
LATER TODAY OR TONIGHT AS THE UPPER TROUGH SLIDES TO THE EAST.
SURFACE NORTHERLIES WILL BE BREEZY THROUGH SATURDAY...BUT WEAKEN
SATURDAY NIGHT AND SUNDAY AS A HIGH PASSES EASTWARD JUST NORTH OF
THE MAIN ISLAND CHAIN. WINDS WILL BECOME LIGHT FROM SUNDAY INTO
EARLY NEXT WEEK AS RIDGING LINGERS BEHIND THE HIGH. SOUTHWESTERLIES
WILL BECOME DOMINANT AFTER MIDWEEK AS ANOTHER COLD FRONT APPROACHES
THE MAIN ISLANDS FROM THE NORTHWEST.

DRY AIR AND SUBSIDENCE ASSOCIATED WITH THE RIDGE WILL KEEP RAINFALL
MINIMAL TO NON-EXISTENT AFTER THE FRONTAL CLOUD BAND PASSES BY. IN
FACT...LITTLE RAINFALL IS EXPECTED ANYWHERE ACROSS THE ISLANDS FROM
SATURDAY THROUGH MIDWEEK...WHEN ANOTHER COLD FRONT IS EXPECTED.
MODELS SHOW THE SECOND FRONT WILL BE WEAKER THAN THIS PAST ONE AND
NOT LIKELY TO PASS MUCH FARTHER SOUTHEAST THAN OAHU. ASSOCIATED
CLOUDS AND SHOWERS WILL FAVOR THE WESTERN END OF THE MAIN ISLAND
CHAIN LATE WEDNESDAY ONWARD THROUGH THE FORECAST PERIOD.

&&

.MARINE...SURF HEIGHTS ARE JUST GRAZING ADVISORY LEVELS ALONG NORTH
FACING SHORES THIS MORNING...ACCORDING TO THE WAIMEA BAY BUOY. WE
EXPECT AN APPROACHING NORTHWEST SWELL TO RAISE SURF HEIGHTS FURTHER
LATER TODAY AND SATURDAY...SO WE ISSUED HIGH SURF ADVISORIES FOR
NORTH AND WEST FACING SHORES OF THE SMALLER ISLANDS. THESE EXPOSURES
ON THE BIG ISLAND MAY BE ADDED LATER. SURF HEIGHTS ARE EXPECTED TO
BEGIN DECLINING SATURDAY NIGHT...FALLING BELOW ADVISORY LEVELS EARLY
MONDAY.

WE WILL ALSO EXPAND AND EXTEND THE SMALL CRAFT ADVISORY TO
ACCOUNT FOR RISING SEAS.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH WIND WARNING THROUGH 6 PM FRIDAY FOR HALEAKALA...MAUNA LOA AND
MAUNA KEA SUMMITS.

SMALL CRAFT ADVISORY THROUGH 6 PM SUNDAY FOR ALL WATERS EXCEPT
