HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
258 AM EDT MON APR 7 2025
VALID 00Z TUE 8 APR 2025 - 00Z TUE 15 APR 2025
SURFACE HIGH PRESSURE REBUILDS NORTHWEST OF THE STATE NEAR 30-35
DEGREES NORTH THROUGH EARLY IN THE WEEK, WITH MAINLY ENE TRADE
WIND FLOW EXPECTED, AND THEN THE HIGH BECOMES CENTERED NORTH OF
THE STATE BY THURSDAY INTO FRIDAY AND MORE EASTERLY FLOW, WITH
GOOD OVERALL MODEL AGREEMENT ACROSS THE HAWAII DOMAIN. A WEAKNESS
LIKELY DEVELOPS IN THE SUBTROPICAL RIDGE AXIS BY SUNDAY NORTH OF
THE STATE, WITH SOME REDUCTION IN THE TRADES POSSIBLE.
IN TERMS OF RAINFALL PROSPECTS, MAINLY TRADE WIND INDUCED SHOWERS
CAN BE EXPECTED MOST DAYS ACROSS THE WINDWARD TERRAIN. THE
ENSEMBLE MEANS SUGGEST AN UPPER TROUGH COULD DEVELOP NEAR 150
DEGREES WEST BY MIDWEEK, AND THIS MAY RESULT IN A SLIGHTLY GREATER
COVERAGE OF SHOWERS DURING THIS TIME, BUT NOTHING MAJOR EXPECTED.
