HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
445 AM EDT MON JUN 1 2026
VALID 00Z TUE 02 JUN 2026 - 00Z TUE 09 JUN 2026
THE PERIOD BEGINS WITH A SERIES OF LOW PRESSURE SYSTEMS LINED UP
FROM JUST SOUTH OF THE ALEUTIANS SOUTHWESTWARD OF NEAR JAPAN.
MID- LEVEL HEIGHT RISES AND INCREASING SURFACE PRESSURE BETWEEN
THE LOWS AND THE ISLANDS WILL GENERALLY KEEP A NORTHEASTERLY FLOW
ACROSS THE STATE FOR MUCH OF THE PERIOD ALTHOUGH WIND SPEEDS
SHOULD GRADUALLY STRENGTHEN BY EARLY NEXT WEEK. THE MODELS STILL
DEPICT AN EAST TO WEST PASSAGE OF A WAVE EARLY IN THE PERIOD THAT
LOOKS TO BOLSTER THE CHANCE OF RAIN WITH MODEST TO PERHAPS LOCALLY
HEAVIER RAINFALL...OVER AT LEAST THE BIG ISLAND (POTENTIALLY INTO
MAUI AND MOLOKAI/LANAI). THEREAFTER, WINDWARD/MAUKA SHOWERS ARE
LIKELY INTO EARLY NEXT WEEK WITH SOME LEEWARD SPILLAGE AMID BREEZY
TRADES.
