AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
355 PM HST SAT DEC 27 2008

.SYNOPSIS...AN UPPER LEVEL LOW OVER THE HAWAIIAN ISLANDS IS
MAINTAINING UNSTABLE ATMOSPHERIC CONDITIONS ACROSS THE STATE.
NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED TO
CONTINUE OVER MOST OF THE ISLAND CHAIN THROUGH THIS EVENING. EXPECT
THE WET TRADE WIND PATTERN TO PERSIST THROUGH THE REMAINDER OF THE
WEEKEND.

&&

.DISCUSSION...
AS OF 345 PM...THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN
HONOLULU HAWAII...ON THE CAMPUS OF THE UNIVERSITY OF HAWAII AT
MANOA...IS BACK ON COMMERCIAL POWER. POWER WAS RESTORED AT THE
OFFICE AROUND 1130 AM THIS MORNING. HOWEVER...DUE TO COMMUNICATION
PROBLEMS THAT RESULTED FROM THE POWER OUTAGE LAST NIGHT...WFO
HONOLULU REMAINS IN DIAL-UP MODE AS A MEANS OF TRANSMITTING
PRODUCTS. DATA FROM MOST SOURCES CONTINUES TO ARRIVE AT THE OFFICE
WITHOUT SIGNIFICANT INTERRUPTION.

WHILE HIGH PRESSURE SITTING NORTHEAST OF THE STATE IS MAINTAINING
MODERATE TO LOCALLY FRESH TRADE WINDS ACROSS THE STATE...THE
ATMOSPHERE HAS BEEN DESTABILIZED BY AN UPPER LEVEL LOW PRESSURE
SYSTEM. WATER VAPOR IMAGERY SHOWS THE UPPER LEVEL LOW HOVERING OVER
THE MAIN HAWAIIAN ISLANDS THIS AFTERNOON ALTHOUGH ITS AXIS APPEARS
TO HAVE SHIFTED EAST OVER THE PAST FEW HOURS...TO A POSITION
SOUTHEAST OF OAHU. THE LOW CONTINUES TO KEEP WEATHER CONDITIONS
ACTIVE AND UNSETTLED ACROSS THE STATE. A COLD POOL OF AIR ASSOCIATED
WITH THE LOW ALOFT IS ONE OF THE INGREDIENTS FOR THE ACTIVE WEATHER.
THE UNSTABLE CONDITIONS IS BEING CREATED BY TEMPERATURES OF -12 TO
-13 DEGREES CELSIUS IN THE MID LEVELS OF THE ATMOSPHERE...TRIGGERING
THE DEVELOPMENT OF HEAVY SHOWERS AND THUNDERSTORMS.

AN AREA OF CONVECTIVE ACTIVITY WAS OVER THE COASTAL WATERS NORTH OF
MAUI COUNTY THIS AFTERNOON. THE UPPER LOW IS PROVIDING ENOUGH
INSTABILITY AND SUPPORT TO MAINTAIN CONVECTION THERE. WESTWARD
PROGRESSION OF THIS AREA HAS BEEN VERY SLOW OVER PAST FEW HOURS. AS
THIS AREA HAS REMAINED NEARLY STATIONARY. THE BROAD AREA MAY BE
SLOW TO REACH OAHU...IF AT ALL. HOWEVER...WITH THE UPPER LOW ALOFT
THE POSSIBILITY OF HEAVY SHOWERS AND THUNDERSTORMS REMAINS AT LEAST
FOR THESE ISLANDS THROUGH THIS EVENING.

FORECAST MODELS ARE SHOWING THE UPPER LEVEL LOW TO WEAKEN INTO A
TROUGH THIS EVENING AND OVERNIGHT. AS THIS FEATURE WEAKENS...THE
THREAT OF THUNDERSTORMS AND HEAVY SHOWERS WILL TAPER OFF. THERE IS
GOOD MODEL AGREEMENT WITH THE TROUGH LINGERING OVER THE ISLANDS
THROUGH THE REMAINDER OF THIS WEEKEND. THIS TROUGH IS FORECAST TO
LIFT TO THE EAST NORTHEAST BY THE START OF THE NEW WORK WEEK.
EXPECT WET TRADE WIND WEATHER TO CONTINUE THROUGH THE WEEKEND WITH
THE GREATEST RAINFALL TOTALS OCCURRING OVER WINDWARD FACING SLOPES.

ANOTHER UPPER LEVEL TROUGH IS EXPECTED TO PUSH IN TOWARD THE STATE
FROM THE NORTHWEST NEXT WEEK...REINFORCING THE TROUGHY PATTERN WEST
OF THE STATE. WEATHER ACROSS THE STATE WILL DEPEND ON HOW THIS
PATTERN SETS UP AND IT PROXIMITY TO THE ISLANDS. THIS SYSTEM WILL
LIKELY HAVE A SURFACE REFLECTION AND MAY CAUSE THE WINDS TO TURN
SOUTHEASTERLY OVER THE WESTERN PART OF THE STATE BY THE MIDDLE OF
NEXT WEEK.

&&

.MARINE...
MODERATE TO LOCALLY FRESH TRADE WINDS HAVE GENERATED A FRESH SWELL
WHICH CONTINUES TO PRODUCE SURF HEIGHTS ABOVE THE HIGH SURF ADVISORY
THRESHOLD ALONG EAST FACING SHORES OF MOST ISLANDS THROUGH TONIGHT.
WAVE HEIGHTS ARE EXPECTED TO GRADUALLY DIMINISH BELOW THIS THRESHOLD
TOMORROW. THE SMALL CRAFT ADVISORY REMAINS IN EFFECT OVER MOST
COASTAL WATERS ZONES DUE TO SEAS OF 10 FEET OR GREATER AND FOR AREAS
OF 25 KNOT WINDS IN THE TYPICALLY WINDY MARINE ZONES.

A NEW WEST NORTHWEST SWELL WILL ARRIVE ON TUESDAY AND BUILD INTO
WEDNESDAY PRODUCING SURF APPROACHING THE HIGH SURF ADVISORY
THRESHOLDS ALONG NORTH AND WEST FACING SHORES OF MANY ISLANDS.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY UNTIL 600 AM HST SUNDAY FOR EAST FACING SHORES
OF KAUAI OAHU MOLOKAI MAUI AND THE BIG ISLAND.

SMALL CRAFT ADVISORY UNTIL 600 AM HST SUNDAY FOR ALL HAWAIIAN
WATERS...EXCEPT THE MAUI COUNTY LEEWARD WATERS.
