HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
359 AM EDT SUN MAR 09 2025
VALID 00Z MON MAR 10 2025 - 00Z MON MAR 17 2025
THE GENERAL PATTERN ACROSS HAWAII THROUGH EARLY TO MIDWEEK WILL
CONSIST OF BREEZY TO WINDY TRADES AND SHOWERS FAVORING
WINDWARD/MAUKA AREAS. SURFACE HIGH PRESSURE WILL SET UP NORTH OF
THE STATE (ON AVERAGE AROUND 35N) TO PROMOTE THESE EASTERLY WINDS.
A WEAK FRONTAL REMNANT IS FORECAST TO PUSH THROUGH SUNDAY INTO
MONDAY, AND THE HREF SHOWS A LINE OF SHOWERS PUSHING SOUTH FROM
KAUAI AND OAHU SUNDAY INTO MAUI SUNDAY NIGHT AND INTO THE BIG
ISLAND BY MONDAY. SOME SHOWERS COULD SPILL OVER INTO LEEWARD
AREAS. A REASONABLY MOIST PATTERN WITH SHOWERS SHOULD PERSIST AS
THE WEEK PROGRESSES.
LATER THIS WEEK INTO NEXT WEEKEND, THE SURFACE HIGH IS FORECAST TO
DRIFT SOUTHEASTWARD, AND MEANWHILE AN UPPER TROUGH PUSHING A COLD
FRONT WILL APPROACH WEST OF THE STATE. THIS COMBINATION SHOULD
ALLOW WINDS TO WEAKEN A BIT BUT REMAIN BREEZY, WHILE VEERING SOME
AND REORIENTING BEST RAIN CHANCES ON THE SOUTHEASTERN SIDES OF THE
ISLANDS. MODEL GUIDANCE SHOWS MOISTURE LEVELS INCREASING BY EARLY
NEXT WEEK AHEAD OF THE FRONT, SO WILL CONTINUE TO MONITOR FOR
POSSIBLE INCREASES IN RAIN AMOUNTS BY THAT TIME.
