HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
315 AM EST SUN JAN 25 2026
VALID 00Z MON 26 JAN 2026 - 00Z MON 02 FEB 2026
A RATHER QUIET WEATHER PATTERN IS EXPECTED TO SET UP ACROSS
HAWAII AND THE SURROUNDING WATERS FOR THE LAST WEEK OF JANUARY AND
TO START FEBRUARY. A FRONT WILL START OUT THE PERIOD SUNDAY
AFTERNOON TO THE NORTH OF THE CHAIN. THIS WILL LIKELY BE THE
STRONGEST FEATURE TO IMPACT THE ISLANDS FOR THE REST OF THE WEEK.
THAT IS NOT SAYING MUCH, AS THE FRONT WILL BE WEAKENING AND
SHEARING APART AS IT MOVES INTO KAUAI, OAHU, AND POSSIBLY AS FAR
SOUTH AS MOLOKAI AND MAUI BEFORE DISSIPATING ENTIRELY. AS THE
FRONT MOVES ACROSS THE NORTHWESTERN ISLANDS, SHOWERS CONSISTING OF
LIGHT TO BRIEFLY MODERATE RAIN WILL IMPACT ALL SIDES OF THE
ISLANDS, PARTICULARLY THE NORTH-FACING SIDES. THESE ARE MOST
LIKELY INTO MONDAY MORNING. ONCE THE FRONT DISSIPATES BY MONDAY
AFTERNOON, THAT WILL BE LARGELY THE END OF ANY LARGER SCALE
FRONTS/FEATURES FOR THE REMAINDER OF THE WEEK.
A LARGE AREA OF HIGH PRESSURE BEHIND MONDAY'S FRONT WILL BUILD
NORTH OF THE ISLANDS AND SET UP WELL NORTHEAST OF THE CHAIN.
HOWEVER, ASSOCIATED SURFACE RIDGING WILL REMAIN OVER THE STATE
THROUGH THE REST OF THE WEEK. ANY ADDITIONAL FRONTS THAT ATTEMPT
TO APPROACH THE ISLANDS FROM THE NORTH ARE IN GOOD AGREEMENT IN
MOST OF THE GUIDANCE TO BE DEFLECTED EAST AND NOT IMPACT THE
CHAIN, ALLOWING THE SURFACE RIDGING TO CONTINUE TO DOMINATE THE
WEATHER PATTERN. AS USUAL, AFTERNOON INSTABILITY COULD KICK UP
LOCAL SHOWER ACTIVITY, BUT THESE WILL BE ISOLATED, FEW, AND FAR
BETWEEN. THUS, THE DRY PERIOD WILL PERSIST INTO THE START OF
FEBRUARY, WITH NO BIG CHANGES TO THE PREDOMINANT WIND PATTERN OUT
OF THE NORTHEAST AS WELL.
