HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
339 AM EDT MON APR 28 2025
VALID 00Z TUE 29 APR 2025 - 00Z TUE 06 MAY 2025
THROUGH TUESDAY EXPECT A SURFACE TROUGH TO BE ALIGNED OVER THE
STATE, KEEPING WINDS LIGHT AND FAVORING A LAND/SEA BREEZE FOCUS
FOR RAINFALL. SOME OF THIS RAINFALL MAY BE LOCALLY HEAVY AND
POSSIBLY ACCOMPANIED BY THUNDER, AIDED BY THE COMBINATION OF ABOVE
NORMAL MOISTURE PLUS A CLOSING UPPER LOW NORTH OF THE STATE
TRACKING BARELY NORTHEAST OF THE MAIN ISLANDS ON TUESDAY.
WEDNESDAY WILL OFFER A TREND BACK TO A TYPICAL TRADE REGIME AS
THE UPPER LOW CONTINUES EASTWARD AND OPENS UP. TRADES SHOULD
STRENGTHEN BY FRIDAY AND THE WEEKEND AS SURFACE HIGH PRESSURE
PASSES BY TO THE NORTH AND NORTHEAST. THE COMBINATION OF THIS HIGH
SETTLING OVER THE EASTERN PACIFIC AND ANOTHER HIGH REACHING THE
CENTRAL PACIFIC WILL LIKELY MAINTAIN FAIRLY BRISK TRADES INTO
MONDAY. SHOWERS SHOULD TREND LIGHTER AS PRECIPITABLE WATER VALUES
REACH NEAR TO BELOW NORMAL VALUES LATE WEEK ONWARD.
