HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
242 AM EST THU JAN 29 2026
VALID 00Z FRI 30 JAN 2026 - 00Z FRI 06 FEB 2026
A WEAKENING FRONT WILL APPROACH THE HAWAIIAN ISLANDS STARTING WITH
KAUAI ON FRIDAY MORNING. IT WILL LIKELY MAKE IT AS FAR SOUTHEAST
AS MAUI AND MOLOKAI BEFORE IT SHEARS APART ENTIRELY. THUS, THE
NORTHWESTERN ISLANDS WILL LIKELY SEE SOME PERIOD OF SHOWER
ACTIVITY FRIDAY AND FRIDAY NIGHT. ONCE THE FRONT DISSIPATES, HIGH
PRESSURE CENTERED WELL NORTHEAST OF THE ISLANDS WILL KEEP THE
CHAIN RELATIVELY QUIET THROUGH THE WEEKEND, WITH FLOW GENERALLY
OUT OF THE SOUTHEAST.
ON MONDAY, A MUCH STRONGER FRONT WILL APPROACH THE ISLANDS FROM
THE NORTHWEST. AHEAD OF THE FRONT, THE FLOW WILL TURN OUT OF THE
SOUTHWEST, ALLOWING THE TYPICALLY DRIER SOUTHWEST SIDES OF THE
ISLANDS TO GET A SOAKING RAIN, WHICH COULD INCLUDE ISOLATED
THUNDERSTORMS. THE RAIN WITH THE FRONT IMPACTS THE MIDDLE OF THE
CHAIN LATE MONDAY NIGHT INTO TUESDAY MORNING, THEN FINALLY LARGELY
DISSIPATES AS IT APPROACHES THE BIG ISLAND TUESDAY NIGHT. HIGH
PRESSURE RETURNS TO CONTROL THE WEATHER WEDNESDAY INTO THURSDAY,
WITH LITTLE RAIN EXPECTED.
