AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE HONOLULU HI
330 AM HST FRI OCT 14 2011

.SYNOPSIS...
A WEAK FRONT WILL REACH THE ISLANDS THIS EVENING...BRINGING AN
INCREASE IN SHOWERS AND GUSTY NORTHEAST WINDS. THE FRONT WILL CLEAR
THE SMALLER ISLANDS SATURDAY MORNING AND LINGER ACROSS THE BIG
ISLAND THROUGH SATURDAY NIGHT. LIGHT TRADES AND DRIER WEATHER WILL
FILL IN BEHIND THE FRONT AND PERSIST THROUGH MONDAY. ANOTHER FRONT
WILL APPROACH THE ISLANDS TOWARD THE MIDDLE TO END OF NEXT WEEK.

&&

.DISCUSSION...
A 1033 MB HIGH HAS MOVED IN NORTH OF THE ISLANDS...BUT A FRONT LIES
BETWEEN THE HIGH AND THE MAIN HAWAIIAN ISLANDS KEEPING LOCAL TRADE
WINDS IN THE MODERATE RANGE THIS MORNING. WE EXPECT MODERATE TRADES
TO CONTINUE THROUGH MOST OF TODAY...WITH EMBEDDED CLOUDS AND SHOWERS
FAVORING WINDWARD AND MAUKA AREAS. SATELLITE LOOP SHOWS SCATTERED
TO PATCHY BROKEN LOW CLOUDS UPWIND FROM THE ISLANDS...WITH EMBEDDED
ISOLATED SHOWERS NOTED ON RADAR. THESE WILL BEGIN TO THIN OUT LATER
THIS MORNING ACROSS THE ISLANDS...FOLLOWING A DIURNAL PATTERN...AND
DRIER WEATHER IS EXPECTED THROUGH MOST OF THE DAY TODAY.

A FRONT 190 MILES NORTH OF THE ISLANDS CONTINUES TO MOVE SOUTHWARD
AND IS EXPECTED TO REACH US THIS EVENING. SATELLITE IMAGERY SHOWS
THAT THE PORTION OF THE FRONT EXPECTED TO AFFECT THE ISLANDS IS
COMPOSED MAINLY OF BROKEN TO OVERCAST LOW CLOUDS. NO STRENGTHENING
IS EXPECTED BETWEEN NOW AND THE TIME IT REACHES THE ISLANDS.
HOWEVER...WE EXPECT AT LEAST SOME RAINFALL WILL OCCUR ALMOST
EVERYWHERE. THE SHOWERS WILL BE LIGHT TO MODERATE AT MOST...SO WHILE
THE POPS ARE HIGH TONIGHT...THE OVERALL RAINFALL AMOUNTS WILL BE
LOW. ALONG WITH THE INCREASE IN SHOWERS TONIGHT...EXPECT GUSTY
NORTHEAST WINDS AND SLIGHTLY COOLER TEMPERATURES. MODELS SHOW THE
FRONT CLEARING THE SMALLER ISLANDS SATURDAY MORNING...BUT LINGERING
A BIT LONGER...THROUGH THE DAY SATURDAY...ON THE BIG ISLAND.

LIGHT TRADES AND DRIER WEATHER WILL FILL IN BEHIND THE FRONT AND
PERSIST THROUGH MONDAY. CURRENT ECMWF AND GFS MODELS SHOW ANOTHER
FRONT APPROACHING THE ISLANDS LATE NEXT WEEK BUT STALLING JUST
NORTHWEST OF KAUAI.

&&

.MARINE...
MODERATE NORTHEASTERLY WINDS WILL CONTINUE ACROSS COASTAL WATERS
WITH THE USUAL INCREASE IN THE CHANNELS THROUGH TODAY. THE FRONTAL
PASSAGE TONIGHT WILL PRODUCE GUSTY WINDS...SHOWERS...AND CHOPPY
SEAS. A SMALL CRAFT ADVISORY WILL LIKELY BE ISSUED FOR THE TYPICAL
WINDY WATERS AROUND MAUI COUNTY AND THE BIG ISLAND LATER TODAY.
WINDS AND SEAS OVER THE NORTHERN COASTAL WATERS MAY ALSO BRIEFLY
REACH ADVISORY LEVELS LATE TODAY AND EARLY SATURDAY. WINDS ARE
EXPECTED TO GRADUALLY DIMINISH AND VEER TO A MORE EASTERLY DIRECTION
LATE SATURDAY NIGHT AND SUNDAY.

&&

.AVIATION...
THE APPROACH AND EVENTUAL PASSAGE OF THE FRONT LATE TODAY/EARLY
SATURDAY WILL LIKELY RESULT IN BRIEF MVFR CEILINGS AND
VISIBILITIES...MAINLY AT THE WINDWARD TERMINALS. INCREASING WINDS
WITH FRONTAL PASSAGE WILL LIKELY NECESSITATE AN AIRMET FOR LOW LEVEL
TURBULENCE...WHILE AN AIRMET FOR MOUNTAIN OBSCURATION IS ALSO
POSSIBLE.

&&

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