HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
309 AM EDT THU JUN 15 2023
VALID 00Z FRI JUN 16 2023 - 00Z FRI JUN 23 2023
THE CORE OF THE SUBTROPICAL HIGH IS EXPECTED TO BE NEARLY ANCHORED
IN PLACE BETWEEN HAWAII AND CALIFORNIA THROUGH THE UPCOMING
WEEKEND, AND THEN MOVE SLIGHTLY TOWARDS THE WEST BY THE EARLY TO
MIDDLE PART OF NEXT WEEK. THE ISLANDS WILL BE ON THE SOUTHWESTERN
PERIPHERY OF THIS HIGH THROUGH THE FORECAST PERIOD. SIMILAR TO
YESTERDAY, THE GEFS MEAN IS SLIGHTLY TO THE WEST WITH THE HIGH
COMPARED TO THE ECENS MEAN BY MONDAY-WEDNESDAY. THIS WILL ALSO BE
CO-LOCATED WITH AN UPPER LEVEL HIGH IN THE SAME GENERAL REGION.
A WEAK UPPER LEVEL TROUGH WILL LIFT SLOWLY NORTHWESTWARD ACROSS
THE EASTERN AND CENTRAL ISLANDS OVER THE NEXT SEVERAL DAYS, BUT IT
SHOULD NOT HAVE A NOTICEABLE EFFECT ON THE LOCAL WEATHER FOR MOST
LOCATIONS. IN TERMS OF SENSIBLE WEATHER, LOW LEVEL TRADES SHOULD
GENERALLY BE OUT OF THE EAST WITH SOME OCCASIONAL ESE COMPONENT AT
TIMES, WITH MODERATE TO BREEZY FLOW VELOCITIES EXPECTED. NO MAJOR
SURGES OF TROPICAL MOISTURE ARE EXPECTED OVER THE NEXT WEEK WITH
THE DEEPEST MOISTURE CONFINED TO THE ITCZ.
