AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST MON AUG 28 2006

.SYNOPSIS...
AS A LOW PRESSURE SYSTEM NORTHWEST OF THE ISLANDS MOVES AWAY...TRADE
WINDS WILL RETURN TO THE ISLANDS. HOWEVER...THERE REMAINS A CHANCE
FOR LOCALLY HEAVY SHOWERS ON KAUAI THROUGH THE DAY TODAY...AND OVER
LEEWARD PORTIONS OF THE BIG ISLAND THIS AFTERNOON. STABLE TRADE WIND
WEATHER WILL RETURN TO ALL ISLANDS TUESDAY...WITH LIGHT SHOWERS
FAVORING WINDWARD AND MAUKA AREAS FOR THE REMAINDER OF THE WEEK.

&&

.DISCUSSION...
CURRENTLY...A COMPLEX LOW ALOFT IS CENTERED NORTH-NORTHWEST /NNW/ OF
THE ISLANDS NEAR 29N 165W...WITH A WEAK SURFACE REFLECTION ANALYZED
IN ROUGHLY THE SAME LOCATION. AN ANTICYCLONE ALOFT IS NORTHEAST OF
THE STATE NEAR 27N 142W...WITH SOUTHWEST FLOW ALOFT OVER THE ISLANDS
BETWEEN THESE TWO FEATURES. AT THE SURFACE...A 1030 MB HIGH IS
CENTERED FAR NORTH OF THE ISLANDS...BUT THE LOW LEVEL FLOW NEAR THE
WESTERN END OF THE CHAIN IS BLOCKED FROM FEELING THE EFFECTS OF THIS
HIGH...DUE TO THE WEAK PRESSURE GRADIENT ASSOCIATED WITH THE
VERTICALLY STACKED LOW TO THE NNW. AN AREA OF LOW LEVEL MOISTURE
CONVERGENCE...BETWEEN THE TRADES BUILDING IN FROM THE EAST AND THE
SOUTHERLIES FEEDING INTO THE SURFACE LOW...IS OVER KAUAI AND
SURROUNDING WATERS THIS MORNING...PRODUCING CLOUDS AND A FEW HEAVY
SHOWERS ALONG A NORTHEAST TO SOUTHWEST ORIENTED BAND...WITH A FEW
HEAVY SHOWERS SOUTHEAST OF KAUAI MOVING NORTHWEST.

LIGHT TO MODERATE TRADE WINDS WILL BRING A FEW CLOUDS AND SHOWERS TO
WINDWARD AREAS OF THE BIG ISLAND...MAUI AND MOLOKAI THIS
MORNING...WHILE A LIGHT WIND REGIME WILL PREVAIL OVER KAUAI AND
OAHU. LIGHT SEA BREEZES HAVE ALREADY BEGUN TO BLOW OVER OAHU AND
KAUAI THIS MORNING...AND ONE OF THE SHORT-TERM FORECAST PROBLEMS/
QUESTIONS IS WHETHER OR NOT CLOUDS AND SHOWERS WILL DEVELOP OVER
OAHU/S INTERIOR LEEWARD SLOPES THIS AFTERNOON. CURRENT THINKING IS
THAT AFTERNOON CLOUDS WILL FAVOR THE WAIANAE SLOPES TODAY...BUT
THEIR EXTENT WILL BE LIMITED DUE TO BOTH THE INCREASING STABILITY
AND LOW LEVEL WINDS...WITH PRESSURE READINGS UP 2 TO 3 MB OVER THE
PAST 24 HOURS. DUE TO THE PRESENCE OF THE CONVERGENCE BAND...KAUAI
WILL BE CLOUDY AND SOMEWHAT SHOWERY TODAY AND INTO TONIGHT...WITH A
CHANCE FOR A LOCALLY HEAVY DOWNPOUR. WILL BE UPDATING GRIDS/
FORECASTS SHORTLY TO REFLECT THIS THINKING.

THE FORECAST FOR THE REMAINDER OF THE WORK WEEK IS A LITTLE MORE
CLEAR- CUT. THE DEEP LAYERED LOW TO THE NORTHWEST WILL LIFT
OUT...AND RIDGING ALOFT WILL BUILD IN FROM THE EAST...RESULTING IN
INCREASED STABILITY AND EASTERLY WINDS...AND A MORE COMFORTABLE AIR
MASS. WATER VAPOR IMAGERY SHOWS AN AREA OF DRIER AIR ALOFT JUST EAST
OF THE ISLANDS...POISED TO MOVE IN ONCE THE LOW LIFTS OUT TO THE
NORTHWEST. SO A RETURN TO A MORE TYPICAL TRADE WIND PATTERN IS IN
THE WORKS...BUT NOT BEFORE ONE MORE DAY OF SOMEWHAT UNSETTLED
WEATHER...ESPECIALLY NEAR KAUAI.

LONGER RANGE OUTLOOK BRINGS A MID LEVEL CUT-OFF LOW OVER THE
ISLANDS FROM THE EAST BY NEXT WEEKEND...BUT CONFIDENCE IS LOW.

&&

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