AS A FRONTAL BOUNDARY TO THE NORTH WEAKENS, THE PRESSURE GRADIENT
ACROSS THE CENTRAL PACIFIC WILL TIGHTEN AND TRADE WINDS WILL
STRENGTHEN TO OPEN THE FIRST HALF OF THE WEEK. THE REVITALIZED
TRADE WIND REGIME WILL ALSO RE-INTRODUCE ELEVATED PW ANOMALIES,
PARTICULARLY THE SECOND HALF OF THE WEEK. LATEST GLOBAL GUIDANCE
SHOWS ONE WEAK TROUGH AXIS APPROACHING THE BIG ISLAND THAT WILL
INTRODUCE ADDED MOISTURE FLUX OVER THE ISLAND CHAIN AND LINGER
INTO THE START OF THE UPCOMING WEEKEND. IT IS NOT UNTIL SUNDAY
AND INTO EARLY NEXT WEEK THAT THE ELEVATED PW ANOMALIES HEAD EAST
AND THE RESULTING CHANCES FOR SHOWERS FOR THE ISLANDS DECREASE.
