HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
153 AM EST SAT NOV 11 2023
VALID 00Z SUN NOV 12 2023 - 00Z SUN NOV 19 2023
MODERATE TO BREEZY TRADES ARE EXPECTED TO SUPPORT SOME MAINLY
WINDWARD SHOWER ACTIVITY OVER THE NEXT COUPLE OF DAYS. MEANWHILE
THOUGH, DEEP UPPER TROUGH AMPLIFICATION OVER THE EASTERN PACIFIC
SEEMS SUFFICIENT IN MOST GUIDANCE TO FORCE A WELL DEFINED COLD
FRONT SOUTHWARD THROUGH THE ISLANDS BY TUESDAY. A FAVORED
COMPOSITE OF MODEL AND ENSEMBLE GUIDANCE SEEMS TO OFFER A GOOD
FORECAST BASIS AMID GROWING FORECAST SPREAD OVER TIME FOR
DEVELOPMENT OF THIS FEATURE. THIS FRONT SHOULD FOCUS MOISTURE AND
AN AXIS OF PRECIPITATION WITH PASSAGE TO AGAIN LIKELY FOCUS ON
WINDWARD AREAS. HIGH PRESSURE BUILDING INTO THE NORTH OF THE STATE
IN THE WAKE OF FRONTAL PASSAGE SHOULD REJUVENATE TRADES THROUGH
NEXT MID-LATE WEEK BEFORE EASING LATE WEEK INTO NEXT WEEKEND, ALL
IN A PATTERN WITH DECREASING MOISTURE AVAILABILITY.
