ISLAND TRADES WILL GRADUALLY WEAKEN TO MORE MODERATE TO BREEZY

BETTER CLUSTERED, BOLSTERING FORECAST CONFIDENCE. TROPICAL  
MOISTURE WILL BE PULLED NORTH TO THE STATE AS TROUGHING AT THE  
SURFACE AND ALOFT SETTLES OVER/WEST OF THE STATE. RECENT GFS RUNS  
AND GEFS MEMBERS HAVE OVERALL BEEN AGGRESSIVE WITH THE TROUGHING,  
BUT LATEST RUNS ARE MORE IN LINE WITH A MODERATE SOLUTION, ALBEIT  
STILL LEADING TO HIGH MOISTURE LEVELS COMING INTO THE STATE WITH  
ENHANCED RAINFALL CHANCES FOCUS TUESDAY-THURSDAY. TRADES AND  
WINDWARD TERRAIN RAIN PATTERN FOCUS SHOULD UPTICK FOR A FEW DAYS  
MID-LATER NEXT WEEK AS RENEWED HIGH PRESSURE BRIDGES TO THE NORTH  
OF THE STATE BEFORE POSSIBLY WEAKENING AGAIN INTO NEXT WEEKEND.
