HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
259 AM EDT WED SEP 20 2023
VALID 00Z THU SEP 21 2023 - 00Z THU SEP 28 2023
STRONG HIGH PRESSURE TO THE NORTH OF HAWAII THIS WEEK SHOULD KEEP
A LOCALLY BREEZY TRADE WIND PATTERN IN PLACE, WITH SOME
VARIABILITY IN SPEEDS. TRADES MAY EASE SOME DURING THE WEEKEND
WITH SOME HEAVIER SHOWERS POSSIBLE AS AN UPPER LEVEL
TROUGH/CYCLONE MOVES NEARBY AND LEADS TO A SLIGHT UPTICK IN THE
PRECIPITABLE WATER VALUES OVER THE ISLANDS. SHOWERS THROUGH THE
NEXT WEEK WILL TEND TO FOCUS OVER THE FAVORABLE WINDWARD/MOUNTAIN
AREAS BUT COULD EXTEND OVER SOME LEEWARD LOCATIONS DEPENDING ON
WIND SPEEDS AND POCKETS OF HIGHER MOISTURE MOVING THROUGH THE
FLOW.
