AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
840 PM HST TUE FEB 28 2006

.SYNOPSIS...
MOIST SOUTHEAST FLOW OVER THE ISLANDS WILL CONTINUE THROUGH
THURSDAY...BRINGING SHOWERS UP FROM SOUTH OF THE ISLANDS. SOME OF
THE SHOWERS COULD BE LOCALLY HEAVY...ESPECIALLY FOR KAUAI. THE AIR
MASS WILL BECOME DRIER BY THE WEEKEND...WITH TRADES RETURNING.

&&

.DISCUSSION...
SOUTHEAST FLOW OVER THE ISLANDS HAS BEEN CARRYING LEE-SIDE
CONVERGENCE PLUME SHOWERS UP OVER KAUAI AND OAHU THIS EVENING. THE
SOUTHEAST FLOW IS NOT EXPECTED TO CHANGE ANYTIME SOON...SO THE DOOR
IS OPEN FOR MORE PLUME SHOWERS TO DEVELOP AND MOVE TOWARD THOSE
ISLANDS OVERNIGHT. THE AFTERNOON SOUNDINGS SHOW THE AIRMASS
CONTINUES TO MOISTEN UP...WITH THE PHLI PRECIPITABLE WATER UP TO
1.63 INCHES.

ADDED LOW POPS FOR SNOW AT THE BIG ISLAND SUMMITS OVERNIGHT...ALONG
WITH AREAS OF FREEZING FOG AS THEY WILL BE IN CLOUD AT TIMES.
OTHERWISE THE GRIDS LOOK PRETTY GOOD AT THIS POINT.

&&

.PREV DISCUSSION...
FROM 340 PM...WIND FLOW FINALLY TURN MORE SOUTHEAST THIS AFTERNOON...
AND CONTINUES TO DO SO AS A FRONT FAR WEST EDGES CLOSER EAST. IT HAS
BEEN RAINING STEADILY OVER KAUAI FOR MOST OF THE DAY...WITH MAJORITY
OF RAIN GAUGES REPORTING LESS THAN A QUARTER OF AN INCH. THE WETTEST
SPOT WAS MT WAIALEALE...WITH OVER 2 INCHES OF RAINFALL IN THE PAST
SIX HOURS. EXPECT THE RAIN TO CONTINUE AS MORE OF RAIN CLOUDS ARE
HEADING THE ISLAND. BELIEVE IT DOES NOT WARRANT A WATCH AT
TIME...THOUGH IT MAY NOT TAKE MUCH TO REACH THAT LEVEL SINCE GROUND
IS ALREADY QUITE SATURATED OVER KAUAI. SHALL KEEP A CLOSE LOOK ON
THIS DEVELOPING SITUATION.

LATEST FORECAST CHARTS FINALLY SHOW SOME CONSISTENCY BETWEEN RUNS.
A GOOD AMOUNT OF MOISTURE WILL PREVAIL OVER THE ISLANDS FOR THE NEXT
FEW DAYS. THERE IS LITTLE DYNAMICS ASSOCIATED WITH THIS EVENT DUE
TO THE LACK OF UPPER LEVEL FEATURES FOR CONVECTION TO DEVELOP. THUS
IT WILL PROBABLY BE THE CONVERGENCE PLUME CLOUDS THAT MAY GIVE
HEAVIER RAIN AT TIMES AND OROGRAPHIC LIFTING ALONG THE MOUNTAINS.
HENCE HAVE CONTINUED THE PREVIOUS FORECAST WITH A SLIGHT CHANCE OF
THUNDERSTORMS FOR KAUAI VICINITY AND PRECIPITATION BECOMING MORE
WIDESPREAD IN THE NEXT TWO DAYS.

IT LOOKS LIKE TRADE WINDS WILL BUILD BACK OVER THE ISLANDS BY THE
WEEKEND...AS A HIGH MOVES TO FAR NORTH OF THE ISLANDS. LOOK FOR MORE
TYPICAL TRADE WIND WEATHER TO PREVAIL THROUGH THE WEEKEND INTO EARLY
NEXT WEEK.

&&

.MARINE...
THE CURRENT NORTH-NORTHEAST SWELL MAY LINGER THROUGH EARLY THURSDAY.
HAVE EXTENDED THE HIGH SURF FOR THE EAST FACING SHORES TILL THEN.
THE SEAS WILL REMAIN HIGH ENOUGH MAINLY FOR THE WINDWARD AND A
COUPLE OF SELECTED LEEWARD WATERS...AS WELL AS THE ALENUIHAHA
CHANNEL TO WARRANT SMALL CRAFT ADVISORY FOR ANOTHER DAY OR SO.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
