AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST WED FEB 15 2006

.SYNOPSIS...
LIGHT TRADE WINDS WILL CARRY SHOWERS...SOME HEAVY...TO ALL ISLANDS.
ADDITIONAL HEAVY SHOWERS AND THUNDERSTORMS ARE POSSIBLE FRIDAY AND
SATURDAY...THANKS TO AN UPPER LEVEL LOW THAT WILL FORM NORTHWEST OF
KAUAI.

&&

.DISCUSSION...
IN THE NEAR TERM...SHOWERS ALONG THE WINDWARD SIDE OF OAHU SHOULD
TAPPER OFF IN AN HOUR OR TWO. UNTIL THEN...MINOR FLOODING WILL OCCUR
IN LOW LAYING AREAS. SHOWERS OVER THE REST OF THE STATE ARE ISOLATED
AND DISORGANIZED...AND POSE NO THREAT OF FLOODING. SHOULD BE A QUIET
NIGHT ONCE WINDWARD OAHU CLEARS OUT.

AS AN ASIDE...THE EAST/WEST ORIENTED RETURNS DETECTED BY NEXRAD
NORTH OF OAHU ARE NOT RAIN...BUT RATHER MILITARY CHAFF.

FARTHER OUT IN TIME...MODEL GUIDANCE APPEARS TO BE ZEROING IN ON A
COMMON SOLUTION REGARDING THE SOMEWHAT COMPLEX WEATHER PATTERN
EXPECTED THE REST OF THIS WEEK. HERE IS WHAT THEY AGREE ON. A CLOSED
UPPER LEVEL LOW WILL FORM THURSDAY NIGHT...AND LINGER JUST NORTHWEST
OF KAUAI THROUGH SATURDAY. TEMPERATURES ALOFT ASSOCIATED WITH THE
LOW WILL BE QUITE COLD...MAKING FOR AN UNSTABLE ATMOSPHERE AND
ENHANCED CONVECTION...ESPECIALLY OVER THE KAUAI END OF THE ISLAND
CHAIN. THE LOW WILL DRIFT WESTWARD SUNDAY AND MONDAY...AND ANY
INFLUENCE ON ISLAND WEATHER WILL LEAVE WITH IT. A SURFACE TROUGH TO
THE EAST WILL MOVE WESTWARD ACROSS THE STATE...RESULTING IN LIGHT
AND WET TRADES. THE TROUGH IS FORECAST TO BE WEST OF US BY
SATURDAY...PUTTING WET SOUTHEAST FLOW OVER THE STATE. AS WITH THE
UPPER LOW...THE SURFACE TROUGH WILL MOVE AWAY TO THE WEST AND
MODERATE TRADE WINDS WILL RETURN BY MONDAY.

MODELS STILL DIFFER ON SPECIFICS...BUT CONSIDERING ALL OF THE LARGE
SCALE STUFF ABOVE...HEAVY SHOWERS AND MAYBE THUNDERSTORMS WILL BE
INSERTED IN THE FORECAST PACKAGE DUE OUT AT 4 AM THURSDAY. BEST SHOT
FOR HEAVY RAIN...FRIDAY AND SATURDAY. AS ALWAYS...WHEN DEALING WITH
SUCH A COMPLEX SCENARIO...FORECASTS WILL BE SUBJECT TO CHANGE.

&&

.MARINE...THE HIGH SURF ALONG NORTH FACING SHORES WILL PROBABLY
LOWER BELOW ADVISORY LEVELS LATE THURSDAY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
 HIGH SURF ADVISORY...NORTH FACING SHORES.
