THE MAIN SUBTROPICAL SURFACE HIGH OVER THE EASTERN PACIFIC WILL BE
POSITIONED WELL NORTH OF THE ISLANDS THIS WEEK, AND THEN THE HIGH
REDEVELOPS NORTHEAST OF THE STATE BY NEXT WEDNESDAY. THE STATE
WILL BE ON THE SOUTHERN PERIPHERY OF THIS HIGH, AND THIS WILL
KEEP A GENERAL EASTERLY LOW LEVEL FLOW IN PLACE, WITH SOME ENE TO
ESE COMPONENT AT TIMES THROUGH THE PERIOD. THE ENSEMBLE MEANS ARE
IN GOOD SYNOPTIC SCALE AGREEMENT ON THE OVERALL PATTERN.
IN TERMS OF RAINFALL PROSPECTS, THE NORMAL TRADE WIND INDUCED
SHOWERS CAN BE EXPECTED THROUGH THE REMAINDER OF THE WEEK WITH NO
MAJOR RAINFALL EVENTS EXPECTED. HOWEVER, THERE MAY BE A SLIGHT
INCREASE IN SHOWERS ACROSS THE BIG ISLAND OVER THE WEEKEND AS A
WEAK TROPICAL WAVE APPROACHES FROM THE EAST, AND ANOTHER SURGE OF
MOISTURE WILL LIKELY PASS SOUTH OF THE ISLANDS AROUND THE MIDDLE
OF NEXT WEEK.
