AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST FRI FEB 24 2012

.SYNOPSIS...
LOW PRESSURE AT THE SURFACE AND ALOFT SETTLING SEVERAL HUNDRED MILES
WEST OF THE STATE WILL PRODUCE OF THREAT OF HEAVY SHOWERS ON KAUAI
AND OAHU LATER TODAY THROUGH THE WEEKEND. THESE FEATURES WILL CAUSE
EASTERLY TRADE WINDS TO VEER OUT OF THE EAST SOUTHEAST NEAR KAUAI
AND POSSIBLY OAHU AND WILL SEND A SHIELD OF HIGH CLOUDS OVER MOST
ISLANDS. INCREASINGLY STABLE WEATHER AND STRONGER TRADE WINDS WILL
RETURN NEXT WEEK AS THE TROUGHS FILL.

&&

.DISCUSSION...
IT/S A QUIET MORNING ACROSS THE STATE...BUT DEVELOPING LOW PRESSURE
TO THE WEST WILL BE A FACTOR FOR ISLAND WEATHER THIS WEEKEND.
DEVELOPING INSTABILITY AHEAD OF THE LOW PRESSURE AREA TRIGGERED SOME
HEAVY SHOWERS ON KAUAI LAST NIGHT AS PART OF THE BIG ISLAND PLUME
DRIFTED UP OVER THE GARDEN ISLE. WE DO NOT EXPECT A REPEAT THIS
MORNING...THOUGH HEAVY SHOWERS MAY FLARE UP AGAIN ON LEEWARD KAUAI
THIS AFTERNOON. ELSEWHERE...A WEAKENING EASTERLY TRADE WIND FLOW
WILL FOCUS CLOUDS AND SHOWERS ACROSS WINDWARD AREAS. HIGH CLOUDS
WILL BE THICKENING FROM WEST TO EAST TODAY AS WELL. A QUICK FORECAST
UPDATE WAS SENT TO BETTER REFLECT MORNING CONDITIONS.

UNSETTLED WEATHER IS POSSIBLE OVER THE WESTERN END OF THE STATE
TONIGHT THROUGH THE WEEKEND. A SURFACE AND UPPER LEVEL TROUGH
CURRENTLY DIGGING 650 MILES NORTHWEST OF KAUAI WILL STALL 150 TO 300
MILES WEST OF THE GARDEN ISLE TONIGHT...BRINGING THE POTENTIAL FOR
HEAVY RAINFALL FOR KAUAI AS WELL AS OAHU. THE TROUGH WILL CAUSE THE
EASTERLY TRADE WIND FLOW TO VEER EAST SOUTHEASTERLY...SETTING UP THE
POTENTIAL FOR CONVERGENCE BANDS WITH HEAVY SHOWERS MOVING OVER KAUAI
IN THE UNSTABLE FLOW. AT THIS TIME...IT LOOKS LIKE THE GREATEST
INSTABILITY WILL REMAIN WEST OF KAUAI...AND CONFIDENCE IS NOT HIGH
ENOUGH TO WARRANT THE ISSUANCE OF A FLASH FLOOD WATCH. HOWEVER...WE
WILL CLOSELY MONITOR THE DEVELOPING SITUATION AS FLOODING RAINS ARE
A POSSIBILITY. ON OAHU...THE GREATEST THREAT WILL BE NARROW PLUMES
OF HEAVY SHOWERS MOVING OFF MOLOKAI AND FOCUSING ALONG WINDWARD
COMMUNITIES. HIGH CLOUDS WILL BLOT OUT MOST OF THE SUNSHINE THROUGH
THE WEEKEND.

OVER THE EASTERN END OF THE STATE...EASTERLY TRADE WINDS PERSIST AND
WEAK RIDGING ALOFT WILL HANG ON. AS A RESULT...MODERATE SHOWERS WILL
BE FOCUSED OVER WINDWARD AREAS...WHILE VARIABLE AMOUNTS OF HIGH
CLOUDS PASS OVERHEAD FROM THE WEST. THAT SAID...THERE MAY BE ENOUGH
INSTABILITY FOR BRIEFLY HEAVY SHOWERS TO POP ON THE KONA SLOPES
DURING THE AFTERNOON HOURS.

HEADING INTO NEXT WEEK...THE SURFACE AND UPPER LEVEL TROUGH TO THE
WEST OF THE STATE LOOK TO WEAKEN AND LOSE INFLUENCE OVER ISLAND
WEATHER. EASTERLY TRADE WINDS WILL STRENGTHEN A NOTCH WHILE A MORE
STABLE PATTERN OF WINDWARD AND MAUKA SHOWERS WILL DEVELOP.

&&

.MARINE...
NO MARINE ADVISORIES ARE IN EFFECT TODAY. TRADE WINDS MAY INCREASE
ENOUGH FOR SMALL CRAFT ADVISORIES TO BE ISSUED FOR THE TYPICALLY
WINDY WATERS AND CHANNELS AROUND THE BIG ISLAND AND MAUI AS EARLY AS
SATURDAY. A NORTHWEST SWELL MAY BRIEFLY PUSH SURF TO HIGH SURF
ADVISORY LEVELS ALONG NORTH AND WEST FACING SHORES OF THE SMALLER
ISLANDS LATE SUNDAY.

&&

.AVIATION...
NO AIRMETS ARE IN PLACE TODAY. ISOL MVFR CIGS WILL BE CONFINED TO
WINDWARD AREAS OF MOST ISLANDS...AS WELL AS THE KONA SLOPES IN THE
AFTERNOON. THE ONE EXCEPTION WILL BE KAUAI...WHERE A GREATER
COVERAGE OF MVFR CIGS ALONG WITH MVFR VIS IN +SHRA MAY DEVELOP THIS
AFTERNOON AND WORSEN TONIGHT.

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