AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE HONOLULU HI
145 PM HST WED MAR 22 2006

.SYNOPSIS...
A KONA LOW WILL REMAIN NORTHWEST OF KAUAI THROUGH EARLY NEXT WEEK.
THE LOW WILL KEEP THE ATMOSPHERE UNSTABLE AND DRAW TROPICAL MOISTURE
UP FROM THE SOUTH. THE THREAT OF HEAVY SHOWERS WILL CONTINUE THROUGH
AT LEAST FRIDAY MORNING. MORE HEAVY SHOWERS COULD COME STARTING
SUNDAY NIGHT.

&&

.UPDATE...
WE HAVE UPDATED THE GRIDS AND TEXT FORECASTS AGAIN TO REDUCE SHOWERS
THIS AFTERNOON AND REMOVE THE FORECAST OF THUNDERSTORMS. THIS
RESPITE FROM HEAVY RAIN IS LIKELY TO BE SHORT-LIVED. SATELLITE AND
RADAR DATA SHOW HEAVY SHOWERS SOUTHWEST OF KAUAI MOVING TOWARDS THE
EAST NORTHEAST. THESE SHOWERS WILL SPREAD OVER THE ISLANDS STARTING
THIS EVENING.

.DISCUSSION...
MOST AREAS ARE GETTING A BREAK FROM HEAVY PRECIPITATION THIS
AFTERNOON. SATELLITE LOOPS SHOW EXTENSIVE CLOUD COVER ACROSS THE
ISLANDS BUT ONLY LIGHT RAIN HAS BEEN FALLING OVER MOST AREAS. RADARS
SHOW SPOTTY SHOWERS OVER THE BIG ISLAND OF HAWAII WITH ISOLATED
HEAVY SHOWERS.

A DEEP TROUGH REMAINS NORTHWEST OF KAUAI WITH A KONA LOW CENTERED
850 MILES WEST NORTHWEST OF KAUAI AT 29N 171W. SOUTHWEST FLOW ALOFT
CONTINUES TO PULL VERY MOIST TROPICAL AIR UP OVER THE ISLANDS. FOR
NOW...THE MOST ACTIVE WEATHER AROUND THE TROUGH IS ABOUT 300 MILES
WEST SOUTHWEST OF KAUAI WHERE SATELLITE IMAGERY SHOWS A SOUTH
SOUTHWEST TO NORTH NORTHEAST BAND OF EMBEDDED THUNDERSTORMS. THE GFS
MODEL SUGGESTS THAT THE HEAVIER RAIN SOUTHWEST OF KAUAI WILL SPREAD
BACK OVER THE MAIN HAWAIIAN ISLANDS OVER THE NEXT 24 HOURS AS AN
IMPULSE ALOFT AND AN ASSOCIATED SURFACE LOW MOVE EAST NORTHEAST.

THE TROUGH WEST OF THE ISLANDS IS FORECAST TO WEAKEN ENOUGH FRIDAY
TO DRY OUT THE WEATHER...AT LEAST TEMPORARILY. THE MODELS STILL
SUGGEST THAT THE TROUGH WILL REMAIN NORTHWEST OF KAUAI THROUGH EARLY
NEXT WEEK. AS LONG AS THE TROUGH PERSISTS WE WILL NOT SEE TRADE
WINDS RETURN AND WE WILL HAVE A CHANCE OF MORE HEAVY SHOWERS. THE
GFS 150 SUGGESTS WE MAY SEE ANOTHER ROUND OF HEAVY SHOWERS SUNDAY
NIGHT THROUGH TUESDAY MORNING AS THE KONA LOW KICKS OUT EAST
NORTHEAST TO THE NORTH OF THE MAIN HAWAIIAN ISLANDS. THE GFS 150
SHOWS MUCH DRIER WEATHER STARTING NEXT TUESDAY AS THE WINDS ALOFT
SHIFT TO NORTHWEST. THE GFS 150 STILL SHOWS NO RETURN OF TRADE WINDS
THROUGH THE END OF THE MONTH.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
FLASH FLOOD WATCH THROUGH LATE THURSDAY NIGHT FOR ALL HAWAIIAN
ISLANDS.
