HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
322 AM EDT SUN MAR 30 2025
VALID 00Z MON 31 MAR 2025 - 00Z MON 07 APR 2025
AN UPPER RIDGE OVER HAWAII SHOULD LINGER INTO SUNDAY BRINGING
WEAKER TRADES AND LIGHTER RAINFALL. BY MONDAY THOUGH, THE RIDGE
SHOULD SLOWLY SHIFT EASTWARD AS A DEEP UPPER LOW DEVELOPS NORTH OF
THE STATE WITHIN AN OVERALL BLOCKY PATTERN. THE GUIDANCE HAS COME
INTO MUCH BETTER AGREEMENT REGARDING THE EVOLUTION OF THIS UPPER
LOW COMPARED TO YESTERDAY. THE COLD FRONT FOR THIS SYSTEM MAY
EVENTUALLY REACH CLOSE TO THE ISLANDS ALLOWING FOR STRENGTHENING
SOUTHERLY WINDS AND SOME INCREASED PRECIPITATION CHANCES FOR
MAINLY THE WESTERN ISLANDS. GUIDANCE SHOWS THE HEAVIEST
PRECIPITATION SHOULD REMAIN WEST OF THE ISLAND CHAIN THOUGH. AS
THE UPPER LOW LIFTS NORTHWARD LATE NEXT WEEK, SURFACE HIGH
PRESSURE MAY AGAIN MOVE IN NORTH OF THE STATE ALLOWING FOR A MORE
TYPICAL TRADE WIND PATTERN.
