HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
401 AM EST SAT JAN 31 2026
VALID 00Z SUN 01 FEB 2026 - 00Z SUN 08 FEB 2026
RELATIVELY SOLID CONTINUITY ACROSS GUIDANCE, BOTH DETERMINISTIC
AND ENSEMBLE BASED FOR THE MEDIUM RANGE ACROSS HAWAII. BY SUNDAY,
THE FOCUS SHIFTS TO A MORE ROBUST MID- LATITUDE TROUGH DIGGING
SOUTHWARD TOWARD THE ISLANDS. THE TIGHTENING SURFACE PRESSURE
GRADIENT WILL LEAD TO BREEZY SOUTHWESTERLY (KONA) WINDS AHEAD OF
THE NEXT SYSTEM, WHICH WILL DRAW IN DEEPER TROPICAL MOISTURE LATE
SUNDAY INTO MONDAY. THE SECOND, STRONGER FRONT IS EXPECTED TO
SWEEP ACROSS THE ARCHIPELAGO MONDAY NIGHT AND TUESDAY, BRINGING A
MORE ORGANIZED AREA OF HEAVIER SHOWERS APPROACHING FROM THE
NORTHWEST. THIS IS STILL WELL FORECAST VIA THE MULTITUDE OF
DETERMINISTIC OUTPUTS WITH A WELL- DEVELOPED AXIS OF ENHANCED PWAT
ANOMALIES ALONG AND JUST AHEAD OF THE PRIMARY FRONT.
DURING THE MIDDLE TO LATTER HALF OF NEXT WEEK (FEB 4-6), THE
ISLANDS WILL SETTLE INTO A POST-FRONTAL REGIME DOMINATED BY A
STRONG SURFACE HIGH BUILDING IN FROM THE NORTHWEST. THIS AS
BREEZY NORTHERLY WINDS ON WEDNESDAY GRADUALLY VEER TOWARD THE MORE
TYPICAL NORTHEASTERLY TRADE WIND PATTERN BY LATE IN THE WEEK.
EXPECT NOTICEABLY COOLER AND DRIER CONDITIONS WITH LOWERING
DEWPOINTS AND OVERNIGHT MINIMUM TEMPS DROPPING INTO THE 60S, EVEN 50S
IN HIGHER ELEVATIONS.
