AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST MON MAR 5 2012

.SYNOPSIS...
A TROUGH ALOFT WEST OF THE STATE WILL INDUCE AN ACTIVE WEATHER
PATTERN THROUGH TUESDAY NIGHT ACROSS THE SMALLER HAWAIIAN ISLANDS.
A NEARLY STATIONARY SURFACE TROUGH IS LOCATED ACROSS THE KAUAI
CHANNEL...WITH STRONG NORTHEAST WINDS BLOWING OVER KAUAI AND LIGHT
WINDS EXPECTED OVER THE OTHER ISLANDS. THE TROUGH WILL WEAKEN ON
TUESDAY AND SO WILL THE WINDS. TRADE WINDS WILL STRENGTHEN DURING
THE LATER PART OF THE WEEK AS A STRONG SURFACE HIGH MOVES TO FAR
NORTH-NORTHWEST OF THE ISLANDS.

&&

.DISCUSSION...
A VERY ACTIVE WEATHER PATTERN REMAINS OVER THE STATE THIS EVENING.
ONLY THE BIG ISLAND HAS FAIRLY QUIET CONDITIONS...EXCEPT FOR STRONG
WESTERLY WINDS BUFFETING THE SUMMITS. WINDS ARE INCREASING AND A
HIGH WIND WARNING MAYBE NEEDED SHORTLY...WILL ASSESS INCOMING DATA.

FOR THE SMALLER ISLANDS...A VIGOROUS UPPER LEVEL TROUGH IS LOCATED
WEST OF THE ISLANDS AND IS INDUCING SURFACE CYCLOGENESIS OVER THE
KAUAI CHANNEL. THE RESULTING PRESSURE DROPS ALONG THE SURFACE
TROUGH IS RESULTING IN STRONG NORTHEAST WINDS OVER KAUAI...AND
STRONG LOW LEVEL CONVERGENCE IN CONCERT WITH MID AND UPPER LEVEL
LIFT. HEAVY SHOWERS AND EMBEDDED THUNDERSTORMS WILL CONTINUE TONIGHT
WITH ENOUGH DYNAMICS AND INSTABILITY TO PRODUCE ISOLATED SEVERE
THUNDERSTORMS CONTAINING STRONG WIND GUSTS FROM MAUI WEST TO OAHU
AND KAUAI. AT THIS TIME...EXPECT THE SURFACE TROUGH TO REMAIN OVER
THE KAUAI CHANNEL AS THE MID AND UPPER LEVEL FORCING IS BEGINNING TO
LIFT NORTHEASTWARD WHICH SHOULD END THE EASTWARD PUSH OF THE TROUGH.
THIS WILL KEEP WINDS LIGHT OVER OAHU AND POINTS EASTWARD TONIGHT
INTO TUESDAY.

AFTER THE TROUGH LIFTS NORTHEAST OF THE STATE LATE TUESDAY AND
WEDNESDAY...TRADES WILL FILL BACK IN ACROSS THE STATE. ENOUGH
INSTABILITY WILL REMAIN FOR ENHANCED TRADE SHOWERS WEDNESDAY...BUT
A STABILIZING TREND IS EXPECTED FOR THE END OF THE WEEK...THUS THE
TRADE SHOWERS WILL REDUCE IN COVERAGE AND INTENSITY. THE WEEKEND
PATTERN STILL FEATURES BREEZY TRADES ACROSS THE ISLANDS AS A RIDGE
REMAINS FAR TO THE NORTH. A STABLE AIRMASS ACROSS THE STATE WILL
KEEP SHOWERS TO A MINIMUM.

&&

.MARINE...
THE LARGE NORTH NORTHEAST SWELL CONTINUES TO POUND THE EAST FACING
SHORES WITH WARNING LEVEL SURF HEIGHTS. IN ADDITION...THE NORTH
FACING SHORES ARE HAVING ADVISORY LEVEL SURF FROM THIS SWELL. THE
SWELL WILL REMAIN AT THESE LEVELS TONIGHT THROUGH TUESDAY...THEN
GRADUALLY DECREASE.

GALE FORCE NORTHEAST WINDS WILL CONTINUE TO BUFFET THE WATERS
SURROUNDING KAUAI TONIGHT...THUS A GALE WARNING REMAINS IN EFFECT.
