HAWAIIAN ISLANDS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
900 PM HST WED DEC 21 2005

.SYNOPSIS...
A RIDGE OVER THE ISLANDS WILL CONTINUE THE LIGHT WINDS...HAZE AND
DRY CONDITIONS. A COLD FRONT WILL MOVE RAPIDLY OVER THE ISLAND
CHAIN THURSDAY NIGHT THROUGH FRIDAY. THE FRONT WILL BRING A BRIEF
PERIOD OF STRONG WINDS...LIGHT RAIN AND AID IN REDUCING THE HAZE
OVER THE ISLANDS. LIGHT TRADES WILL RETURN FRIDAY AFTERNOON AND
CONTINUE INTO NEXT WEEK.

&&

.DISCUSSION...
A STRONG JET CONTINUES ACROSS THE NORTH PACIFIC THIS
EVENING...OVERNIGHT THE JET BEGINS TO BUCKLE INTO THE MERIDIONAL
DIRECTION. THIS WILL HELP INTO PUSH THE FRONT LOCATED OFF TO THE
NORTHWEST OF KAUAI THROUGH THE ISLAND CHAIN STARTING THURSDAY NIGHT
THROUGH FRIDAY. THEN ANOTHER RIDGE BUILDS DOWN TO JUST NORTH OF THE
STATE FOR LIGHT TRADES THIS WEEKEND.

TONIGHT BIGGEST ISSUE HAS BEEN THE HAZE AROUND THE ISLANDS.
VISIBILITIES HAVE BEEN ABOVE THE AVIATION REPORTING CRITERIA OF
LESS THAN 7 MILES...HOWEVER MANY OF THE MOUNTAIN VIEWS AND SKY HAS A
NOTICEABLE HAZE.

THE FRONT REACHES KAUAI BY 06Z FRIDAY OR THURSDAY EVENING...AND THEN
BY FRIDAY MORNING OR 18Z FRIDAY LIES OVER MAUI COUNTY. THE FRONT
BECOMES WEAK AND PASSES THROUGH THE BIG ISLAND BY FRIDAY EVENING OR
06Z SATURDAY. IT IS GOING TO BE HARD TO GET A GOOD HANDLE ON THE
POTENTIAL IMPACTS. FOR PRECIPITATION... NOT MUCH WITH THIS FRONT.
BOUNDARY LAYER DOES MOISTEN UP WITH THE PRE-FRONTAL SURGE. HOWEVER
IT IS BONE DRY ABOVE 750 MB AND THAT SHOULD KEEP THE SHOWERS
ISOLATED ACROSS THE REGION. BOTH THE NAM AND GFS AGREE ON THIS AND
KEEPS WITH THE CURRENT THINKING. THIS FRONT DOES APPROACH IN SIMILAR
FASHION AS LAST WEEK/S KONA WIND EVENT...HOWEVER THE DIFFERENCE WITH
THIS SYSTEM THE DEVELOPING LOW IS MUCH FURTHER OFF TO THE NORTHEAST
OF THE ISLANDS. ANOTHER DIFFERENCE IS THAT THE JET STREAM IS MUCH
STRONGER AT UPPER LEVELS. THE ISLAND CHAIN REMAINS UNDER THE
CONVERGENT RIGHT EXIT QUADRANT OF JET MAXIMUM AS IT PASSES JUST OFF
TO THE NORTHEAST. FOR SEVERAL RUNS NOW TIME HEIGHT DIAGRAMS FROM THE
ISLANDS SHOW SUSTAINED WINDS FROM THE LAYER OF 500 TO 700 MB IN THE
RANGE OF 25 TO 45 KNOTS. THIS CORRESPONDS WELL WITH THE UPPER
ELEVATIONS OF THE BIG ISLAND AND HALEAKALA SUMMIT ON MAUI WIND
REGIME. NAM SHOWS GOOD DOWNWARD MOTION BEHIND THE UPPER FRONT OF -4
TO -5 MICROBARS IN THE LAYER FROM 350 TO 450 MB WHICH SHOULD PROVIDE
GUSTS IN EXCESS OF 60 MPH FOR THE SUMMITS. IN THE LOWER LEVELS...IN
THE PRE-FRONTAL SOUTHWESTERLIES OR /KONA DIRECTION/ WINDS IF THE
LAYER BECOMES WELL MIXED TO 600 TO 700 MB 25 TO 40 KNOTS WINDS COULD
COME DOWN TO THE SURFACE IN THE FORM OF GUSTS. SINCE THE FRONT IS
EXPECTED TO PASS DURING THE NIGHTTIME HOURS THE MIXING MAY NOT GET
ALL THE WAY UP TO TAP THE STRONGEST WINDS FOR NOW WILL NOT PUSH
GUSTS INTO THE ADVISORY LEVEL FOR SEA LEVEL AREAS BASED ON THAT.
STAY TUNED SINCE FURTHER MODEL RUNS AND METEOROLOGICAL DEBATE COULD
CHANGE BY THE MORNING PRESS TIME.

AFTER FRIDAY...LIGHT TRADES WILL MOVE INTO THE REGION FOR THE
WEEKEND. NEXT FRONT COULD PASS BY ON TUESDAY...HOWEVER THE GFS IS
BACKING OFF PUSHING THE FRONT THROUGH THE ISLANDS.

&&

.MARINE...
SURF WILL RISE RAPIDLY ALONG NORTH AND WEST FACING SHORES OF
KAUAI THURSDAY AFTERNOON...THEN SPREAD DOWN TO THE BIG ISLAND
THURSDAY NIGHT. SURF WILL LIKELY RISE TO WARNING LEVELS
FRIDAY...THEN DECREASE SATURDAY. GOING TO LEAVE THE ADVISORY AS IS
UNTIL THE MORNING SURF FORECAST...THEN DO EXPECT AN UPGRADE TO A
WARNING FOR THURSDAY NIGHT THROUGH SATURDAY UP AND DOWN THE ISLAND
CHAIN IN THE NORMAL NORTH AND WEST FACING AREAS.

THE HIGH SURF ADVISORY CURRENTLY IN EFFECT FOR WEST FACING SHORES OF
THE BIG ISLAND HAS BEEN EXTENDED INTO SATURDAY. SURF THERE WILL BE
BELOW THE 8 FOOT ADVISORY LEVEL THURSDAY...BUT THE EXTENSION TAKES
INTO ACCOUNT THE ARRIVAL OF THE NEXT NORTHWEST SWELL THURSDAY NIGHT.

ANOTHER EVEN LARGER NORTHWEST SWELL IS FORECAST TO ARRIVE SUNDAY
WITH SURF LIKELY RISING WELL ABOVE THE WARNING LEVELS SUNDAY NIGHT
AND MONDAY.

&&

.FIRE WEATHER...
THE FRONTAL PASSAGE WILL BRING EXTREME FIRE DANGER TO THE USUAL
SPOTS ON THE ISLAND CHAIN WITH THE LACK OF SIGNIFICANT RAINFALL IN
THE PAST WEEK.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...

HIGH WIND WATCH FOR THE SUMMIT OF HALEAKALA FROM THURSDAY EVENING
THROUGH FRIDAY AFTERNOON...AND THE SUMMITS OF MAUNA KEA AND MAUNA
LOA ON THE BIG ISLAND FROM THURSDAY EVENING THROUGH EARLY SATURDAY
MORNING.
