HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
359 AM EDT SAT NOV 04 2023
VALID 00Z SUN NOV 05 2023 - 00Z SUN NOV 12 2023
HIGH PRESSURE TO THE NORTH OF HAWAII WILL INCREASE THE PRESSURE
GRADIENT AND THEREFORE ENHANCE THE TRADE WINDS OVER THE STATE TO
BREEZY TO WINDY LEVELS FOR THE NEXT FEW DAYS. UPPER-LEVEL RIDGING
ALOFT WILL CAUSE LOW AVAILABLE MOISTURE AND GENERALLY DRY
CONDITIONS, WHICH COMBINED WITH THE WINDS WILL LEAD TO FIRE
WEATHER CONCERNS. THE EXCEPTION TO THE DRYNESS COULD BE WITH A
FRONTAL BOUNDARY THAT IS FORECAST TO STALL TO THE NORTH OF THE
STATE THIS WEEKEND, WITH POOLING MOISTURE JUST AHEAD OF IT
SNEAKING INTO KAUAI BY EARLY NEXT WEEK. RAIN CHANCES LOOK TO PEAK
THERE AROUND MONDAY-TUESDAY AND PERHAPS LASTING INTO MIDWEEK. THE
RIDGE ALOFT LOOKS TO START WEAKENING AROUND TUESDAY, THOUGH WITH
SOME DIFFERENCES IN THE DETAILS OF THE RESULTING MID-UPPER FLOW.
AT THE SURFACE, TRADES SHOULD ON AVERAGE REMAIN MODERATE TO
BREEZY. THIS COULD ALLOW FOR INCREASING WINDWARD/MAUKA SHOWERS FOR
THE LATTER HALF OF NEXT WEEK.
