HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
342 AM EDT MON APR 29 2024
VALID 00Z TUE APR 30 2024 - 00Z TUE MAY 07 2024
GENERALLY EAST-SOUTHEAST TO EAST WINDS ARE PRESENT ACROSS HAWAII,
WITH THE SLIGHT VEERING OF THE WINDS DUE TO UPPER AND SURFACE LOWS
TO THE NORTHWEST OF THE STATE. THESE WINDS SHOULD STAY LIGHT TO
MODERATE OVER THE EASTERN ISLANDS OVER THE NEXT COUPLE OF DAYS,
WITH LIMITED SHOWERS. MEANWHILE WINDS SHOULD BE WEAK ENOUGH OVER
THE NORTHWESTERN ISLANDS TO ALLOW FOR A HYBRID TRADE AND LAND/SEA
BREEZE PATTERN, WHILE A TONGUE OF MOISTURE COMES INTO KAUAI AND
PRODUCES SHOWERS. THE HREF ALSO SHOWS SOME ENHANCEMENT OF SHOWERS
FARTHER EAST ACROSS MAUI LATE MONDAY.
FOR MIDWEEK AND BEYOND, SURFACE HIGHS DEVELOPING NORTH OF THE
STATE WILL LEAD TO GRADUALLY INCREASING EASTERLY TRADES, REACHING
MODERATE TO BREEZY LEVELS BY FRIDAY AND LASTING INTO EARLY NEXT
WEEK. MEANWHILE MODEL GUIDANCE IS IN FAIRLY GOOD AGREEMENT WITH
SHOWING A MID-UPPER TROUGH/LOW CENTERED WEST OF HAWAII FRIDAY AND
THEN COMING OVERHEAD OVER THE WEEKEND. THIS SHOULD PROVIDE SOME
INSTABILITY FOR INCREASED SHOWERS, WHICH WOULD FAVOR WINDWARD
AREAS GIVEN THE INCREASING TRADES.
