HAWAII EXTENDED FORECAST DISCUSSION  
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
347 AM EDT MON JUN 03 2024  
 
VALID 00Z TUE JUN 04 2024 - 00Z TUE JUN 11 2024  
 
ON MONDAY, EXPECT A PATTERN FAVORABLE FOR SHOWERS ACROSS THE STATE  
AND PERHAPS EVEN THUNDERSTORMS OVER THE BIG ISLAND, AS A CLOSED  
LOW ALOFT SHOULD ALLOW FOR SOME INSTABILITY TO DEVELOP WHILE ABOVE  
NORMAL MOISTURE (PRECIPITABLE WATER VALUES) COME IN. AN ELONGATED  
SURFACE HIGH PRESSURE SYSTEM IS IN PLACE TO KEEP TRADES BREEZY, SO  
MANY SHOWERS SHOULD FOCUS IN WINDWARD/MAUKA AREAS. MOISTURE LEVELS  
COULD BE SLOW TO DROP INTO TUESDAY, BUT THE INVERSION ALOFT WILL  
NOT ALLOW FOR MUCH SHOWER DEVELOPMENT, PER THE HREF. TRADES MAY  
STAY BREEZY TUESDAY BUT GRADUALLY DROP WEDNESDAY AND ESPECIALLY  
THURSDAY AS THE ELONGATED SURFACE HIGH IS LIKELY TO SPLIT NORTH OF  
HAWAII AND DECREASE THE PRESSURE GRADIENT. MEANWHILE MID-UPPER  
HEIGHTS WILL RISE AS THE PATTERN ALOFT FLIPS TO RIDGING. THUS A  
DRY PATTERN WITH LAND/SEA BREEZES IN SOME AREAS IS FORECAST FOR  
LATE WEEK. TRADES LOOK TO GRADUALLY INCREASE A BIT INTO THE  
WEEKEND AND EARLY NEXT WEEK.
