AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST SAT DEC 1 2007

.SYNOPSIS...
A WEAKENING COLD FRONT NORTH OF THE STATE WILL BRING SCATTERED
SHOWERS TO THE SMALLER ISLANDS TONIGHT...WITH KAUAI EXPECTED TO SEE
THE MOST RAIN. SOUTHWEST WINDS WILL INCREASE TONIGHT AND SUNDAY
AHEAD OF A STRONGER COLD FRONT...WHICH WILL MOVE ACROSS KAUAI AND
OAHU ON SUNDAY BEFORE STALLING OVER MAUI COUNTY MONDAY. THIS FRONT
WILL BRING WIDESPREAD SHOWERS AND THE POTENTIAL FOR HEAVY RAINFALL
TO THE SMALLER ISLANDS.

&&

.DISCUSSION...
A DISSIPATING COLD FRONT IS LOCATED NORTH OF THE STATE...WITH
SHOWERS CONTINUING TO DEVELOP IN THE MOIST AIRMASS SOUTH OF THE OLD
BOUNDARY. 04Z POES AMSU TOTAL PRECIPITABLE WATER SENSOR SHOWS 1.8
INCHES NEAR KAUAI...WHICH IS SUPPORTED BY THE 00Z PHLI SOUNDING.
EXPECT SHOWERS WILL INCREASE IN COVERAGE OVERNIGHT ACROSS THE
COASTAL WATERS...WITH THE KONA WINDS BRINGING THE GREATEST RAINFALL
TO THE TRADITIONAL LEEWARD AREAS.

THE STRONGER COLD FRONT THAT WILL AFFECT THE STATE EARLY NEXT WEEK
IS CURRENTLY ABOUT 500 MILES NORTHWEST OF HONOLULU. 00Z GFS IS
PRETTY CONSISTENT WITH ITS EARLIER RUNS AS FAR AS TIMING...BRINGING
THE FRONT ACROSS KAUAI AND OAHU ON SUNDAY AND STALLING IT OVER MAUI
COUNTY SUNDAY NIGHT/MONDAY. THE EXISTING AIRMASS IS ALREADY QUITE
MOIST...AND SHOWERS WILL INCREASE IN COVERAGE ALONG AND AHEAD OF THE
BOUNDARY. THE MAIN UPPER-LEVEL JET/SHORTWAVE REMAIN NORTH OF THE
STATE...CARVING OUT A BROAD TROUGH OVER THE REGION. CONSEQUENTLY...
MID-LEVEL COLD ADVECTION IS PRETTY WEAK THROUGH THE FIRST PART OF
THE WEEK. HOWEVER...ENOUGH MOISTURE POOLS ALONG THE SURFACE TROUGH
TO WARRANT MENTION OF HEAVY RAINS POSSIBLE.

DEEP SOUTHWESTERLY FLOW HAS ALREADY STARTED TO PICK UP AHEAD OF THE
NEXT FRONT...WITH GUSTY DOWNSLOPE WINDS OCCURRING AT TRADITIONAL
WINDWARD LOCATIONS. WINDS AT HALEAKALA HAVE SLOWLY INCREASED DURING
THE EVENING...AND BEAR FURTHER WATCHING FOR A POTENTIAL WIND
ADVISORY. THE LOCAL HIGH RESOLUTION WRF-NMM FROM 00Z/01 SHOWS SUMMIT
LEVEL WINDS INCREASING ABOVE ADVISORY LEVELS SUNDAY MORNING. THIS IS
SOMEWHAT IN LINE WITH THE 00Z/02 RUNS OF THE NAM AND GFS. A 04Z
DESCENT SOUNDING INTO PHLI AND THE PHKI VWP SHOW WINDS HAVE
INCREASED A FEW KNOTS SINCE THE 00Z PHLI RAOB...WITH WIND SPEEDS
THAT WOULD BE INDICATIVE OF AN ADVISORY AT SUMMIT LEVEL. WILL ISSUE
A WIND ADVISORY THIS EVENING FOR LEAD TIME AS WINDS ARE EXPECTED TO
INCREASE NEAR THE START OF THE SUNDAY PERIOD. THERE ARE A COUPLE
WIND SENSORS ON MAUNA KEA THAT ARE REPORTING WINDS NEAR 30 MPH AS
WELL. HOWEVER...THE DIRECTIONS OF THE WINDS LEAD ME TO BELIEVE THAT
THEY ARE UNREPRESENTATIVE. THE BULK OF THE SENSORS REMAIN MUCH
LIGHTER...WHICH IS MORE IN LINE WITH THE OVERALL SYNOPTIC AND
MESOSCALE PATTERNS. THEREFORE WILL ONLY INCLUDE HALEAKALA IN THE
ADVISORY FOR NOW.

THE 00Z GFS CONTINUES TO STICK WITH A WETTER SOLUTION THROUGH THE
BULK OF THE WORK WEEK...WITH A CUTOFF LOW DEVELOPING NORTHWEST OF
THE STATE IN TUESDAY/WEDNESDAY AND LINGERING THROUGH THE END OF THE
WORK WEEK. THE COLD FRONT THAT STALLS NEAR MAUI COUNTY WOULD LIFT
NORTHWARD AND GET ABSORBED INTO THE DEVELOPING SYSTEM. THE 12Z/01
ECMWF IS ACTUALLY RATHER SIMILAR TO THE GFS...BUT WITH DIFFERENCES
IN THE EXACT PLACEMENT AND TIMING. INSTABILITY WILL INCREASE
QUICKLY BY MID-WEEK WITH COLD MID-LEVEL TEMPERATURES AND ABUNDANT
ANTECEDENT MOISTURE. IF THIS SCENARIO PANS OUT...WE COULD SEE HEAVY
RAIN AND POSSIBLE THUNDERSTORMS OVER PORTIONS OF THE STATE IN THE
WEDNESDAY THROUGH FRIDAY TIME FRAME.

&&

.MARINE...
THE NORTHWEST SWELL PEAKED AT 13 FT/15 SEC AT THE WAIMEA BUOY EARLY
THIS AFTERNOON AND HAD SLOWLY SUBSIDED TO 10 FT THIS EVENING. WILL
LET THE HIGH SURF WARNING EXPIRE AT 10 PM THIS EVENING...TO BE
REPLACED BY THE HIGH SURF ADVISORY.

SMALL CRAFT REMAINS FOR MOST HAWAIIAN COASTAL WATERS DUE TO
HAZARDOUS SEAS PRODUCED BY THE LARGE NORTHWEST SWELL.
