MODELS AND ENSEMBLES REASONABLY AGREE THAT ISLAND TRADES SITUATED
WELL UNDERNEATH HIGHER LATITUDE BLOCKING PERIODICALLY ENHANCES AS
PRESSURE GRAIDENTS TIGHTEN WITH PASSAGE OF A SERIES OF TROPICAL
FEATURES TO THE SOUTH OF THE STATE. A FAVORED GUIDANCE COMPOSITE
INDICATES THAT THIS OCCURS EVEN WITH ANY WEAKENING OF HIGH
PRESSURE BRIDGED TO THE NORTH OF THE STATE IN RESPONSE TO THE
BLOCK. MOISTURE AND SHOWERS MAY ENHANCE OTHERWISE LIMITED WINDWARD
SHOWERS AS THE REMNANTS OF GENEVIEVE NOW NEAR 144W PASS JUST SOUTH
OF THE ISLANDS BY FRIDAY/SATURDAY AS FOLLOWED BY THE CENTRAL
PACIFIC HURRICANE CENTER. ANOTHER TROPICAL DISTURBANCE UPSTREAM
NEAR 134W IS BEING MONITORED BY THE NATIONAL HURRICANE CENTER AND
COULD SPREAD MORE MOISTURE INTO THE STATE BY SUNDAY/MONDAY.
