GUIDANCE CONTINUES TO AGREE THAT BROAD SURFACE HIGH PRESSURE WILL
REMAIN IN PLACE TO THE NORTH OF THE STATE WITH PERSISTENT
MODERATE TRADE WINDS EXPECTED THIS WEEK. THIS WILL FAVOR
UPSLOPE/MAUKA SHOWERS EACH DAY. A PLUME OF HIGHER MOISTURE
ASSOCIATED WITH A TROPICAL WAVE WILL REACH THE ISLANDS BY LATE
WEEK/EARLY THIS WEEKEND BRINGING A BRIEF INCREASE IN SHOWER
CHANCES/RAINFALL BEFORE DRIER CONDITIONS RETURN INTO EARLY NEXT
WEEK. SOME GUSTIER TRADE WINDS MAY ACCOMPANY THE WAVE AS WELL. THE
GUIDANCE HAS BEGUN TO SIGNAL THAT THE SURFACE HIGH MAY DRIFT
NORTHWARD EARLY TO MID-NEXT WEEK WITH A WEAKER PRESSURE GRADIENT
LEADING TO LIGHTER TRADE WINDS.
