HAWAIIAN ISLANDS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 PM HST MON AUG 2 2004

.SYNOPSIS...
LIGHT TO MODERATE TRADE WINDS WILL CONTINUE ACROSS THE ISLANDS
THANKS TO AN AREA OF HIGH PRESSURE TO OUR NORTH. REMNANT MOISTURE
FROM FORMER TROPICAL DEPRESSION DARBY WILL MOVE ACROSS THE ISLANDS
TONIGHT THROUGH TUESDAY. THIS WILL CAUSE AN INCREASE IN SHOWERS OVER
WINDWARD AND MAUKA AREAS WITH LEE AREAS GETTING SOME SHOWERS AT
TIMES. ISOLATED THUNDERSTORMS ARE ALSO A POSSIBILITY THROUGH
TOMORROW AS WELL. SHOWERS MAY INCREASE AGAIN BY THE END OF THE WEEK
AS ANOTHER AREA OF MOISTURE IS EXPECTED TO MOVE THROUGH THE ISLANDS.

&&

.DISCUSSION...
AN AREA OF HIGH PRESSURE FAR TO THE NORTH OF THE ISLANDS WILL KEEP
LIGHT TO MODERATE TRADE WINDS BLOWING ACROSS THE STATE THROUGH THE
FORECAST PERIOD. OUR WINDS WILL DROP OFF A NOTCH TONIGHT THROUGH
TUESDAY AS A WEAK TROUGH IN THE LOW LEVEL EASTERLIES MOVES THROUGH
THE ISLANDS. THIS TROUGH WAS AT ONE TIME HURRICANE DARBY. LAST
NIGHTS QUIKSCAT IMAGE SHOWED LIGHTER WINDS WITH THE SYSTEM BUT THIS
MORNINGS PASS MISSED THE SYSTEM COMPLETELY. WETTER WEATHER IS
EXPECTED OVER THE NEXT 24 TO 36 HOURS AS THE MOISTURE ASSOCIATED
WITH THE REMNANTS OF DARBY PASS THROUGH THE ISLANDS FROM THE EAST.
SHOWERS WILL FAVOR WINDWARD AND MAUKA AREAS BUT LEE AREA MAY ALSO
GET IN ON SOME OF THE SHOWER ACTIVITY AS WELL. WE HAVE RAISED THE
POPS FOR THE TONIGHT THROUGH TOMORROW PERIODS AND HAVE ALSO ADDED
THUNDERSTORMS TO THE FORECAST THROUGH TOMORROW.

ON WEDNESDAY AND THURSDAY OUR WEATHER WILL LIKELY RETURN TO A NORMAL
TRADE WIND PATTERN WITH JUST THE USUAL SHOWER ACTIVITY EXPECTED
MAINLY OVER WINDWARD AND MAUKA AREAS. ANOTHER AREA OF MOISTURE IS
FORECAST TO MOVE INTO THE AREA BEGINNING AROUND FRIDAY AND WILL
LIKELY AFFECT OUR WEATHER THRU SATURDAY. THIS AREA OF MOISTURE IS
ASSOCIATED WITH WHAT IS NOW TROPICAL DEPRESSION SIX E. THIS MOISTURE
AREA MAY PASS FURTHER SOUTH THAN DARBYS MOISTURE BUT WILL STILL UP
THE POPS TO ACCOUNT FOR THE POTENTIAL OF INCREASED RAINFALL.

IN THE UPPER LEVELS OF THE ATMOSPHERE A TROUGH OF LOW PRESSURE IS
EXPECTED TO REMAIN JUST TO OUR NORTHWEST KEEPING CONDITIONS SLIGHTLY
UNSTABLE THROUGH THE FORECAST PERIOD. THIS INSTABILITY IS EVIDENT ON
BOTH THE LIHUE AND HILO SOUNDINGS.
