HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
318 AM EDT WED JUN 14 2023
VALID 00Z THU JUN 15 2023 - 00Z THU JUN 22 2023
THE CORE OF THE SUBTROPICAL HIGH IS EXPECTED TO BE NEARLY ANCHORED
IN PLACE AROUND 35N/145W THROUGH THE UPCOMING WEEK, AND THEN
SLOWLY MOVE BACK TOWARDS THE WEST BY THE MIDDLE OF NEXT WEEK. THE
ISLANDS WILL BE ON THE SOUTHWESTERN PERIPHERY OF THIS HIGH THROUGH
THE FORECAST PERIOD. 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.
THERE WILL LIKELY BE A WEAK UPPER LEVEL TROUGH THAT LIFTS SLOWLY
NORTHWESTWARD THROUGH THE END OF THE WEEK, BUT EXCEPT FOR SOME
SLIGHTLY HEAVIER SHOWERS ACROSS THE BIG ISLAND, 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.
