HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
347 AM EDT WED OCT 04 2023
VALID 00Z THU OCT 05 2023 - 00Z THU OCT 12 2023
A LAND AND SEA BREEZE PATTERN WILL BE IN PLACE OVER HAWAII FOR THE
NEXT COUPLE DAYS, AS TRADES HAVE DIMINISHED AS A RESULT OF A WEAK
PRESSURE GRADIENT DUE TO A SURFACE LOW WELL NORTH OF THE STATE
PUSHING A FRONT ACROSS THE PACIFIC AND HOVERING NORTH NEAR THE
ISLANDS. CLOUDS AND ANY SHOWERS THAT FORM WILL FAVOR THAT LAND/SEA
BREEZE PATTERN THROUGH WEDNESDAY AND PERHAPS INTO THURSDAY. THE
FRONT LOOKS TO STALL AND DISSIPATE JUST NORTH OF HAWAII AROUND
WEDNESDAY NIGHT/THURSDAY, WITH MOST MODELS SHOWING ANY ENHANCED
RAINFALL WITH THE FRONT STAYING TO THE NORTH AS WELL. BY THURSDAY
AND BEYOND, A SURFACE HIGH IS FORECAST TO FORM NORTHWEST OF THE
STATE AND EXTEND ITS RIDGE TOWARD HAWAII, WITH ITS PRESSURE
GRADIENT SUFFICIENT TO REFORM EASTERLY TRADES. A HYBRID TRADE/SEA
BREEZE PATTERN LOOKS POSSIBLE ON THURSDAY BEFORE A MORE TYPICAL
TRADE WIND PATTERN FORMS ON FRIDAY AND SHOULD PERSIST THROUGH THE
WEEKEND INTO EARLY NEXT WEEK, WITH ANY SHOWERS FOCUSED ON
WINDWARD/MAUKA AREAS.
