VALID 00Z THU DEC 08 2022 - 00Z THU DEC 15 2022
MODEL AND ENSEMBLE SOLUTIONS REASONABLY AGREE WITH THE PATTERN
EVOLUTION FOR THE NEXT WEEK, BOLSTERING FORECAST CONFIDENCE. A
CLOSED TROUGH/LOW NOW TO THE NORTHWEST OF THE ISLANDS IS LOSING
INFLUENCE OVER THE STATE AS IT EJECTS NORTHWESTWARD AWAY FROM THE
STATE. HIGH PRESSURE BRIDGING/BUILDING TO THE NORTHEAST OF THE
STATE IN THE WAKE OF CLOSED LOW DEPARTURE SHOULD SUPPORT A RETURN
OF MODERATE TO BREEZY EASTERLY TRADES IN A PATTERN WITH MORE
LIMITED MOISTURE AND WINDWARD TERRAIN FOCUSING SHOWERS UNDER AN
AMPLIFYING UPPER RIDGE FOR MUCH OF THE FORECAST PERIOD. THERE IS A
GUIDANCE SIGNAL TO MONITOR THAT SHOWS SEPARATED/CLOSED LOW ENERGY
SET TO WORK SOUTHWESTARD TO JUST SOUTHEAST OF THE ISLANDS LATE
WEEKEND INTO EARLY-MID NEXT WEEK, BUT RECENT GUIDANCE SEEMS TO
HOLD DEEPER MOISTURE ASSOCIATED WITH THE FEATURE OFFSHORE THE BIG
ISLAND.
