POSSIBLE IN THIS PATTERN, ESPECIALLY WEDNESDAY TO FRIDAY ACROSS  
THE BIG ISLAND AND MAUI WITH SOME SLIGHTLY INCREASED INSTABILITY  
WITH A WEAK LOW ALOFT. BY FRIDAY, TRADES ARE FORECAST TO WEAKEN A  
BIT TO MORE MODERATE TO BREEZY LEVELS, LASTING THROUGH THE  
WEEKEND. BY EARLY NEXT WEEK, AMPLE TROPICAL MOISTURE IS LIKELY TO  
GET PULLED NORTH AS TROUGHING AT THE SURFACE AND ALOFT PRODUCES  
SOUTHERLY FLOW. THERE IS A SIGNAL FOR HEAVY RAINFALL BUT WILL
