HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
418 AM EDT FRI MAY 1 2026
VALID 00Z SAT 02 MAY 2026 - 00Z SAT 09 MAY 2026
THE BIG ISLAND OF HAWAII IN PARTICULAR WILL BE UNDER THE INFLUENCE
OF AN UPPER LOW TO THE EAST OF THE STATE TODAY (FRIDAY), YIELDING
SOME ENHANCED RAINFALL IN WINDWARD AND MAUKA AREAS AS BREEZY
TRADES PERSIST. THE UPPER LOW IS FORECAST TO PULL AWAY OVER THE
WEEKEND, LESSENING SUPPORT ALOFT FOR CONVECTION, BUT SOME SHOWERS
SHOULD STILL OCCUR IN WINDWARD AND MAUKA LOCATIONS. THE MODERATE
TO BREEZY TRADES SHOULD CONTINUE INTO EARLY NEXT WEEK GIVEN
PACIFIC SURFACE HIGHS WELL NORTH OF THE ISLANDS. BY AROUND TUESDAY
OR WEDNESDAY, WINDS MAY LESSEN IN RESPONSE TO A WEAK FRONT
APPROACHING FROM THE NORTH, AND PERHAPS ALLOW FOR LAND/SEA
BREEZES. THIS FRONT OR BOUNDARY DOES NOT APPEAR TO BE VERY
MOISTURE-RICH, BUT MOISTURE (PWS) MAY TICK UP SLIGHTLY BY MID TO
LATE WEEK, ESPECIALLY ACCORDING TO THE ECMWF. QPF LOOKS TO STAY
GENERALLY LIGHT THOUGH, WITH DIURNALLY DRIVEN SHOWERS.
