MODELS AND ENSEMBLES GENERALLY AGREE THAT WEAKENING UPPER RIDGING  
OVER THE REGION WILL SHIFT WESTWARD AND BE REPLACED BY TROUGHING  
THIS WEEKEND INTO NEXT WEEK, NUDGING WESTWARD PAST 150W. THIS  
SUPPORTS A FAIRLY QUIET PATTERN THROUGH THE WEEKEND WITH GENERALLY  
LIGHT WINDWARD/MAUKA SHOWERS VIA MODEST TRADES. PRECIPITABLE WATER  
VALUES ARE FORECAST TO REMAIN NEAR TO BELOW AVERAGE FOR EARLY  
NOVEMBER UNTIL NEXT WEEK WHEN AN INCREASE IS LIKELY. THIS SHOULD  
BRING AN INCREASE TO SHOWER ACTIVITY OVER THE EASTERN ISLANDS (BIG  
ISLAND AND MAUI) AS WELL AS FAVORED WINDWARD AREAS.
