AN UPPER LOW WELL NORTHEAST OF HAWAII WILL SLOWLY CONTINUE TO
PULL AWAY TODAY (WEDNESDAY). AT THE SURFACE, SOME BREEZY
NORTHEASTERLY TRADES ARE IN PLACE THAT SHOULD CONTINUE TO PRODUCE
WINDWARD SHOWERS, ESPECIALLY FOR EASTERN SLOPES OF THE BIG ISLAND
AND MAUI PER THE HREF. SHOWER COVERAGE SHOULD LESSEN INTO LATE
WEEK WHILE WEAK UPPER RIDGING TAKES HOLD, PROMOTING STABILITY
ALOFT FOR GRADUALLY DRIER WEATHER ON THURSDAY AND FRIDAY.
INTO THE WEEKEND, AN UPPER TROUGH/LOW NORTHWEST OF HAWAII WILL
SLOWLY APPROACH WHILE PUSHING A SURFACE COLD FRONT CLOSER TO THE
STATE. CURRENTLY MODELS SHOW THE FRONT STAYING WEST OF KAUAI INTO
SATURDAY FOR ANOTHER MOSTLY DRY DAY ACROSS THE STATE, BUT SURFACE
WINDS SHOULD VEER TO SOUTHEASTERLY AND SOUTHERLY IN THE WESTERN
ISLANDS IN RESPONSE TO THE FRONT. BY SUNDAY AND MONDAY, A PLUME OF
MOISTURE AND INSTABILITY IS FORECAST TO COME INTO ALL ISLANDS FOR
INCREASED RAIN CHANCES, WITH THE EXACT TIMING AND RAIN AMOUNTS
SOMEWHAT UNCERTAIN. SOME MOISTURE COULD LINGER INTO TUESDAY-
WEDNESDAY, BUT LOSE UPPER LEVEL DYNAMICAL SUPPORT AS THE TROUGH
LIFTS NORTHEAST. MEANWHILE AT THE SURFACE, HIGH PRESSURE WILL SET
UP TO THE NORTHEAST AND PROMOTE BREEZY EASTERLY TRADE WINDS. THUS
A MORE TYPICAL EASTERLY TRADE WIND PATTERN SHOULD SET UP BY THEN,
WITH SOME SHOWERS FAVORING WINDWARD/MAUKA AREAS.
