AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST WED MAR 12 2014

.SYNOPSIS...
HIGH PRESSURE FAR NORTHEAST OF THE STATE WILL MAINTAIN A TRADE WIND
WEATHER PATTERN INTO FRIDAY. CLOUDS AND BRIEF LIGHT SHOWERS WILL BE
FOCUSED OVER WINDWARD AND MAUKA AREAS. A WEAKENING FRONT IS EXPECTED
TO MOVE ACROSS THE ISLANDS FRIDAY NIGHT THROUGH SATURDAY
NIGHT...WHICH WILL BRING AN INCREASE IN SHOWER ACTIVITY. A STRONG
HIGH BUILDING IN BEHIND THE FRONT WILL BRING STRONG AND GUSTY TRADE
WINDS FOR THE WEEKEND...AND INTO EARLY NEXT WEEK. WHILE CLOUDS AND
SHOWERS WILL BE FOCUSED OVER WINDWARD AND MAUKA AREAS...THE STRONG
WINDS WILL CARRY PASSING SHOWERS OVER LEEWARD AREAS AT TIMES. THE
TRADES ARE EXPECTED TO DIMINISH TO MODERATE LEVELS DURING THE MIDDLE
OF THE WEEK.

&&

.DISCUSSION...
THERE IS LITTLE CHANGE TO THE FORECAST PHILOSOPHY AT THIS TIME. HIGH
PRESSURE FAR NORTHEAST OF THE AREA CONTINUES TO BRING TRADE WINDS TO
THE ISLANDS TONIGHT...AND THESE SHOULD PERSIST INTO FRIDAY. LIMITED
UPSTREAM MOISTURE MEANS LIMITED SHOWERS BEING CARRIED IN ON THE
TRADES. THURSDAY LOOKS TO BE A REPEAT OF WEDNESDAY.

WINDS ON MAUNA KEA CONTINUE TO REMAIN AT ADVISORY LEVELS...AND THESE
WINDS ARE EXPECTED TO CONTINUE THROUGH MUCH OF THURSDAY. THE GFS
INDICATES THAT THE WINDS SHOULD BE PEAKING NOW AT THE BIG ISLAND
SUMMITS...AND GRADUALLY DIMINISHING THURSDAY...DROPPING BELOW
ADVISORY BY THURSDAY EVENING.

MODELS REMAIN IN GOOD AGREEMENT WITH A FRONT APPROACHING THE ISLANDS
FRIDAY FROM THE NORTHWEST. THERE REMAINS NO DEFINITIVE WIND SHIFT
OVER THE ISLANDS...SO BELIEVE THE FRONT WILL WEAKEN TO A SHEARLINE
BY THE TIME IT REACHES THE ISLANDS FRIDAY NIGHT. MOISTURE WILL
REMAIN LIMITED WITH THIS SYSTEM...BUT EXPECT SHOWERS TO EXPAND FROM
WINDWARD AND MAUKA AREAS TO INCLUDE OTHER AREAS OF THE ISLANDS
FRIDAY NIGHT AND SATURDAY.

THE MODELS REMAIN CONSISTENT IN BUILDING A STRONG HIGH PRESSURE
SYSTEM BEHIND THE FRONT. THIS WILL BRING INCREASING NORTH NORTHEAST
TO NORTHEAST WINDS TO THE ISLANDS SATURDAY AND SUNDAY. THE STRONGEST
WINDS ARE EXPECTED SUNDAY...AND A FEW LOCATIONS SUCH AS LEEWARD
KOHALA MAY APPROACH WARNING LEVELS DURING THAT TIME. TRADE WINDS
WILL BEGIN TO WEAKEN A BIT TUESDAY AND WEDNESDAY AS THE HIGH MOVES
TO A POSITION FAR TO OUR NORTHEAST.

&&

.MARINE...
MODERATE TRADES CURRENTLY OVER THE ISLANDS CONTINUE A SMALL CRAFT
ADVISORY /SCA/ FOR THE ALENUIHAHA CHANNEL. WINDS WILL LIKELY DROP
OFF BRIEFLY THURSDAY NIGHT AND EARLY FRIDAY...BUT THEN EXPECT WINDS
TO RAMP UP AGAIN ACROSS ALL THE WATERS LATER FRIDAY AND THROUGH THE
WEEKEND. WINDS...AND SEAS...WILL EXCEED SMALL CRAFT ADVISORY LEVELS
OVER THE WEEKEND ACROSS THE ENTIRE FORECAST AREA WITH GALE FORCE
WINDS LIKELY OVER THE TYPICALLY WINDY ZONES BY SATURDAY EVENING. A
GALE WATCH COULD BE ISSUED AS EARLY AS THURSDAY AFTERNOON FOR THIS
UPCOMING WIND EVENT.

THE CURRENT NORTHWEST SWELL HAS PEAKED AND WILL GRADUALLY LOWER
THROUGH THURSDAY. A SLIGHTLY LARGER NORTHWEST SWELL IS EXPECTED
FOR FRIDAY AND SATURDAY WITH SURF HEIGHTS REACHING ADVISORY LEVELS.
STRONG TRADE WINDS OVER THE WEEKEND WILL CAUSE A SIGNIFICANT
INCREASE IN SHORT PERIOD CHOPPY SURF ALONG EAST FACING SHORES.

&&

AIRMET TANGO IS IN EFFECT FOR LOW LEVEL TURBULENCE...MAINLY
AFFECTING AREAS OVER AND DOWNWIND OF THE MOUNTAINS.
