HAWAII EXTENDED FORECAST DISCUSSION  
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
359 AM EDT FRI APR 26 2024  
 
VALID 00Z SAT APR 27 2024 - 00Z SAT MAY 04 2024  
 
BREEZY TRADES MAY HOLD THROUGH FRIDAY WITH UPPER/SURFACE HIGHS  
CENTERED NORTHEAST OF HAWAII, BUT THESE FEATURES WEAKENING WILL  
CAUSE WINDS TO WEAKEN AS WELL BY SATURDAY. MEANWHILE TO THE  
NORTHWEST OF THE STATE, UPPER/SURFACE LOWS WILL TRACK SLOWLY  
EASTWARD INTO THIS WEEKEND AND EARLY NEXT WEEK. IN RESPONSE TO  
THESE FEATURES, WINDS ARE LIKELY TO VEER A BIT AND MAY BECOME  
EAST-SOUTHEAST. WINDS ARE FORECAST TO STAY AT WEAK TO MODERATE  
LEVELS AND PERHAPS BECOME A HYBRID TRADE AND LAND/SEA BREEZE  
PATTERN. MINOR MOISTURE PLUMES MAY ALSO BE DRAWN INTO THE STATE AT  
TIMES, WITH THE FIRST FRIDAY NIGHT INTO SATURDAY INCREASING  
SHOWERS PARTICULARLY OVER WINDWARD AREAS OF THE BIG ISLAND  
ACCORDING TO THE HREF. GENERALLY WINDWARD SHOWERS WILL BE THE MAIN  
CHANCE FOR PRECIPITATION, SINCE THE UPPER RIDGE EAST OF HAWAII IS  
LIKELY TO BLOCK THE WESTERN LOWS/ASSOCIATED FRONTAL SYSTEM AND ANY  
HEAVIER PRECIPITATION FROM REACHING EVEN THE NORTHWESTERN ISLANDS  
THROUGH EARLY NEXT WEEK. WHAT IS LEFT OF THE WEAKENING TROUGH MAY  
MOVE ACROSS HAWAII AROUND MIDWEEK OR SO. BY THE LATER PART OF NEXT  
WEEK, SURFACE HIGH PRESSURE IS FORECAST TO MOVE NORTH OF THE STATE  
AND PROMOTE STRENGTHENING EASTERLY TRADES.
