AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 AM HST SUN OCT 8 2006

.SYNOPSIS...LIGHT WINDS WILL CONTINUE FOR THE NEXT WEEK...WITH
DAYTIME SEA BREEZES AND NIGHTTIME LAND BREEZES OVER THE ISLANDS.
THE LACK OF TRADE WINDS MEANS THAT THE RATHER MUGGY CONDITIONS WILL
CONTINUE. THE SEA BREEZES WILL BRING AFTERNOON AND EVENING CLOUDS
OVER ISLAND SLOPES...AND A CHANCE OF SHOWERS...WITH SKIES CLEARING
OVERNIGHT. OVERALL...THE WEATHER PATTERN WILL BE MOSTLY DRY...EXCEPT
FOR INCREASED RAIN CHANCES OVER THE BIG ISLAND SLOPES IN THE
AFTERNOONS...AND NEAR KAUAI AND OAHU MONDAY AND TUESDAY AS AN
APPROACHING FRONT STALLS TO OUR NORTHWEST.

&&

.DISCUSSION...THE CURRENT SURFACE ANALYSES OF THE CENTRAL NORTH
PACIFIC REVEALS A COMPLEX DEVELOPING STORM TO THE NORTHWEST OF THE
MAIN HAWAIIAN ISLANDS...WITH IT/S MAIN CENTER NEAR 43N 165W...AND A
1031MB HIGH FAR NORTHEAST OF THE ISLANDS NEAR 40N 135W. A RIDGE
EXTENDING SOUTHWESTWARD FROM THIS HIGH IS NEAR KAUAI THIS
MORNING...WITH WINDS AT BUOY 51001 OUT OF THE SOUTH...WHILE THE
OTHER BUOYS SOUTH OF THE ISLANDS ARE REPORTING WINDS GENERALLY FROM
THE EAST AND SOUTHEAST. LIGHT TO NIL WINDS PREVAIL OVER LAND
AREAS...WITH MOST STATIONS REPORTING LAND BREEZES. HIGH CLOUDS HAVE
THINNED OVER THE ISLANDS OVERNIGHT...AS THE AXIS OF A CIRRUS-
PRODUCING UPPER TROUGH HAS BEGUN TO SHIFT EAST OF THE ISLANDS.
SHOWERS DEVELOPED OVERNIGHT WITHIN A CYCLONIC ROTOR WEST OF THE BIG
ISLAND...AND BROUGHT A BRIEF PERIOD OF MODERATE TO HEAVY SHOWERS TO
KAILUA-KONA AND SURROUNDING AREAS. A FEW OF THOSE SHOWERS ARE STILL
SEEN ON RADAR OVER LEEWARD BIG ISLAND WATERS...NEAR KEAHOLE
POINT...WITH ADDITIONAL SHOWERS SEEN WITHIN THE BIG ISLAND PLUME
WELL SOUTH OF THE SMALLER ISLANDS. OVERNIGHT SOUNDINGS REVEAL A
DRYING TREND IN THE COLUMN ABOVE HILO...AND A WEAK INVERSION NEAR
7000 FEET...WHILE A SIMILARLY WEAK INVERSION IS SEEN IN LIHUE/S
SOUNDING...NEAR 5500 FEET.

THE SURFACE WIND PATTERN THROUGH THE NEXT 7 DAYS IS EXPECTED TO
CHANGE LITTLE...WITH THE RIDGE REMAINING NEAR THE ISLANDS. NEAR
KAUAI...THE WINDS WILL FAVOR A LIGHT SOUTH TO SOUTHWEST
DIRECTION...WITH LIGHT EAST WINDS PREVAILING NEAR AND SOUTH OF THE
BIG ISLAND. LIGHT SOUTH TO SOUTHEAST WINDS WILL EXIST OVER THE
ISLANDS IN-BETWEEN...INCREASING THE POTENTIAL FOR VOLCANIC HAZE...OR
VOG...BEING CARRIED OVER THE SMALLER ISLANDS FROM THE SOUTH...BUT
WILL REFRAIN FROM INCLUDING HAZE IN THE GRIDS FOR NOW.

AS WOULD BE EXPECTED WITH A SURFACE RIDGE NEAR/OVER THE ISLANDS...
WEATHER IS EXPECTED TO BE ON THE DRY SIDE THROUGH THE UPCOMING
WEEK...WITH A COUPLE OF CAVEATS. THESE INCLUDE THE BIG ISLAND SLOPES
INDUCING SHOWER DEVELOPMENT AS SEA BREEZES CONVERGE IN THE
AFTERNOON...AND THE PRESENCE OF A FRONT TO OUR NORTHWEST. ALTHOUGH
OVERNIGHT SOUNDING DATA INDICATE A SLIGHT STABILIZING TREND NEAR THE
BIG ISLAND...DAYTIME HEATING IS STILL EXPECTED TO PROVIDE ENOUGH
LIFT TO DRIVE SHOWERS...SOME POSSIBLY BRIEFLY HEAVY...OVER THE BIG
ISLAND SLOPES TODAY...AND THIS IS NOT EXPECTED TO CHANGE MUCH THIS
WEEK. THE AFOREMENTIONED FRONT IS ASSOCIATED WITH THE STORM LOW TO
OUR NORTHWEST...AND IT WILL MOVE TOWARD THE ISLANDS OVER THE NEXT
SEVERAL DAYS...BEFORE SLOWING DOWN AND DISSIPATING NORTH OF THE
ISLANDS WEDNESDAY AND THURSDAY. WHILE THE FRONT ITSELF IS NOT
EXPECTED TO AFFECT THE ISLANDS DIRECTLY...WEAKLY CONVERGENT FLOW
SOUTHEAST OF THE FRONT IS PORTRAYED BY GLOBAL MODELS AS BRINGING
INCREASED RAIN CHANCES TO THE ISLANDS AS THE NEW WORK WEEK BEGINS.
INITIALLY THIS PRE-FRONTAL CONVERGENCE WOULD BE NEAR KAUAI LATE
TONIGHT AND MONDAY...THEN SPREADING TO NEAR OAHU AND MOLOKAI MONDAY
NIGHT AND TUESDAY. UPPER AIR SUPPORT FOR BOTH THE FRONT AND
PRE-FRONTAL CONVERGENCE WILL BE MINIMAL AT OUR LATITUDE /AS ONE
MIGHT EXPECT WITH A FRONTAL APPROACH IN EARLY OCTOBER/...WITH NORTH
TO NORTHWEST FLOW IN THE UPPER ATMOSPHERE PREVENTING CONVECTION FROM
BECOMING EXTREMELY DEEP.

AFTER THE FRONT DISSIPATES AROUND MID-WEEK...THE WEAKLY CONVERGENT
FLOW WILL DISSIPATE...AND THE SURFACE RIDGE WILL REMAIN OVER THE
ISLANDS...WITH THE GENERALLY DRY WEATHER PATTERN CONTINUING INTO
NEXT WEEKEND.

&&

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