AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
835 PM HST TUE MAR 19 2013

.SYNOPSIS...
SOUTHERLY WINDS WILL GRADUALLY STRENGTHEN ACROSS KAUAI AND OAHU
THROUGH WEDNESDAY...THEN SPREADING TO THE OTHER ISLANDS BY
THURSDAY. A WEAKENING COLD FRONT WILL REACH THE ISLAND CHAIN BY
FRIDAY AND BRINGING INCREASING SHOWERS. THE FRONT IS EXPECTED TO
STALL OVER THE CENTRAL PORTIONS OF THE STATE DURING THE WEEKEND.
NORTHEASTERLY WINDS WILL THEN BUILD ACROSS THE AREA BEHIND THE
FRONTAL PASSAGE.

&&

.DISCUSSION...
THE SFC RIDGE NE OF THE MAIN HAWAIIAN ISLANDS REMAINS IN PLACE
TONIGHT WHILE A WEAK COLD FRONT SOME 400 MILES NW OF KAUAI GRADUALLY
MOVES TOWARDS THE ISLANDS. WINDS ARE SLOWLY INCREASING AND BECOMING
SE/S OVER THE WESTERN HALF OF THE ISLAND CHAIN.

LATEST RADAR DATA SHOWS SOME LOCALIZED HEAVY SHOWERS AROUND HANA
AND HAMOA OVER MAUI...NEARLY STATIONARY. A WEAK LINE OF SHOWERS WAS
ALSO MOVING ACROSS NW OAHU. THESE SHOWERS SHOULD CONTINUE THROUGH
THE NEXT HOUR OR SO. ADDITIONAL BRIEF SHOWERS ARE POSSIBLE TONIGHT
WITH SYNOPTIC FORCING FROM THE INCREASING SOUTHERLY FLOW DRIVING
THIS NIGHT TIME ACTIVITY.

AN UPPER LVL TROUGH MOVE TOWARDS THE ISLANDS FROM THE NW ON
THU...AND PASSES N OF THE STATE BY FRI. CONDITIONS WILL BECOME
MORE UNSTABLE ACROSS THE AREA WITH SHOWERS DEVELOPING AHEAD OF THE
APPROACHING COLD FRONT AS EARLY AS WED AFTERNOON. SEA BREEZE
CIRCULATIONS WILL HELP IN ENHANCING SOME OF THE AFTERNOON AND EARLY
EVENING SHOWERS. BY THU...SHOWER ACTIVITY WILL BE INCREASING ACROSS
THE ISLAND CHAIN...THEN THE FRONT MOVES ACROSS KAUAI AND OAHU IN THE
FRI AFTERNOON-EVENING TIME FRAME. KAUAI AND OAHU WILL PROBABLY HAVE
THE BEST CHANCES FOR RAINFALL.

THE FRONT WILL BE DISSIPATING BY THE TIME IT REACHES THE EASTERN
HALF OF THE ISLAND CHAIN. MODELS SHOW BETTER AGREEMENT IN THE
SOLUTION FOR THIS SYSTEM...STALLING THE DECAYING BOUNDARY NEAR MAUI
LATE SAT. THE TRADES WILL BEGIN TO BUILD BACK ACROSS THE ISLANDS IN
THE WAKE OF THE FROPA AND CONTINUE THROUGH THE LONG RANGE PART OF
THE FORECAST.

IN ADDITION...AN UPPER LVL JET WILL PASS OVER THE AREA THU THROUGH
SUN AND BRING STREAMING HIGH CLOUDS ACROSS THE ISLANDS.

&&

.AVIATION...
ISOL MVFR CEILING VIS SHRA CONDITIONS CONTINUE OVER EAST MAUI AND
LOWER SLOPE AND COAST OF BIG ISLAND THIS EVENING AS CONVECTION
LINGER. EXPECT THE CONDITIONS TO PERSIST FOR THOSE AREAS THROUGH THE
REST OF THIS EVENING...THOUGH CONDITIONS SHOULD IMPROVE BY EARLY
WEDNESDAY MORNING. OTHERWISE MAINLY VFR CONDITIONS PREVAIL THROUGH
WEDNESDAY FOR ALL TAF SITES. ANOTHER ROUND OF DAYTIME CONVECTION IS
EXPECTED OVER THE ISLANDS UNDER LIGHT WINDS...BRINGING ISOL MVFR
CEILING VIS SHRA CONDITIONS ONCE AGAIN.

&&

.MARINE...
THE NORTH SWELL WILL DECLINE THROUGH WEDNESDAY...THEN THE
FORERUNNERS OF ANOTHER NW SWELL WILL BEGIN ARRIVING ALSO ON
WEDNESDAY. HOWEVER...THE BULK OF THE ENERGY WILL REACH THE ISLANDS
WEDNESDAY NIGHT. THIS WILL LIKELY BRING ADVISORY SURF HEIGHTS TO
NORTH AND WEST SHORES OF THE SMALLER ISLANDS. MODERATE SOUTH TO
SOUTHEAST WINDS IN CONJUNCTION WITH THIS SWELL WILL BUILD COMBINED
SEAS TO SMALL CRAFT ADVISORY HEIGHTS FOR MOST OF THE COASTAL ZONES.
OTHERWISE...SMALL LONG-PERIOD SOUTH SWELL WILL STICK AROUND THROUGH
THE REST OF THE WEEK.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY FOR THE BIG ISLAND SUMMITS UNTIL WEDNESDAY MORNING.
