HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
320 AM EST SAT NOV 29 2025
VALID 00Z SUN 30 NOV 2025 - 00Z SUN 07 DEC 2025
GUIDANCE CONTINUES TO DEPICT A PAIR OF RELATIVELY STRONG FRONTS
TRAILING SOUTH FROM CYCLONES IN THE MID-LATITUDES TO APPROACH OR
REACH THE ISLANDS DURING THE FORECAST PERIOD. THE FIRST FRONT
SHOULD MAKE ITS CLOSEST APPROACH THIS WEEKEND BUT STAYING NORTH OF
THE ISLANDS BEFORE IT WEAKENS. A SECOND, AND POSSIBLY THIRD,
FRONT APPEARS TO APPROACH THE REGION BY MIDWEEK NEXT WEEK, AND
POSSIBLY STALL OVER OR NEAR KAUAI LATE NEXT WEEK. THIS LOOKS TO
BRING A PERIOD OF INCREASED, POSSIBLY HEAVY, PRECIPITATION TO
MAINLY KAUAI AS A POSSIBLE CUT OFF LOW DRIFTS SOUTHWARD TO THE
WEST OF HAWAII. WIND SPEEDS ACROSS MUCH OF HAWAII, BUT ESPECIALLY
THE WESTERN ISLANDS, LOOK QUITE GUSTY BY NEXT FRIDAY AND SATURDAY.
