HAWAIIAN ISLANDS SYNOPTIC DISCUSSION AND GUIDANCE
NATIONAL WEATHER SERVICE HONOLULU HI
10 AM HST SUN MAY 28 2000

SUMMARY...PARTLY CLOUDY WITH A FEW SHOWERS TODAY AS AN UPPER LOW 
LINGERS TO THE SOUTH OF KAUAI. SUNNIER WITH ONLY BRIEF TRADE
SHOWERS MEMORIAL DAY.

DISCUSSION...AN UPPER LOW IS NEARLY STATIONARY 150 MILES SOUTHWEST
OF OAHU. THIS CIRCULATION HAS BEEN PRODUCING HIGH BASED CONVECTION
THAT PRODUCED LIGHTNING AND THUNDER LAST NIGHT BUT LITTLE RAINFALL
OVER THE ISLANDS. THESE CLOUDS ARE NOW MAINLY OVER AND SOUTHWEST
OF OAHU AND ARE MOVING TO THE SOUTH OF KAUAI. DAYTIME HEATING ON
THE CLOUD TOPS MAY CAUSE SOME WEAKENING AND THUNDERSTORMS ARE NOT
THOUGHT TO BE LIKELY THIS AFTERNOON ALTHOUGH SOME COULD DEVELOP
AGAIN TONIGHT ESPECIALLY NEAR KAUAI. THE LOW IS EXPECTED TO MOVE
NORTHEAST AND RAPIDLY WEAKEN OVER THE NEXT 24 HOURS SO THERE WILL
BE LESS OF A CHANCE OF A REPEAT PERFORMANCE TONIGHT. IT IS
INTERESTING THAT THIS MID LEVEL LOW REMAINS UNCOUPLED FROM THE
TRADE WIND LAYER BELOW IT. TRADE CLOUDS OVER THE WINDWARD SLOPES
AND UPWIND TO THE EAST HAVE SO FAR NOT BEEN ENHANCED BY THE POOL
OF COLD AIR ALOFT.

A 1034 MB HIGH PASSING TO THE NORTH OF THE ISLANDS TODAY WILL
SUPPORT MODERATE TO LOCALLY FRESH 10 TO 25 MPH TRADE WINDS TODAY
AND MONDAY. LIGHT TO MODERATE TRADES WILL PREVAIL LATER IN THE
WEEK AS LOW PRESSURE FAR NORTH OF THE ISLANDS WEAKENS THE
SUBTROPICAL RIDGE NEAR THE ISLAoNDS. ONLY THE USUAL BRIEF TRADE
SHOWERS ARE INCLUDED IN THE EXTENDED FORECAST THROUGH THURSDAY.
