THE CORE OF THE SUBTROPICAL HIGH IS EXPECTED TO BE NEARLY ANCHORED
IN PLACE AROUND 35N/145W THROUGH THE UPCOMING WEEK, AND THE
ISLANDS WILL BE ON THE SOUTHWESTERN PERIPHERY OF THIS HIGH. THE
GEFS MEAN IS SLIGHTLY CLOSER TO THE STATE WITH THE HIGH COMPARED
TO THE ECENS MEAN BY SATURDAY AND BEYOND. THIS WILL ALSO BE
CO-LOCATED WITH A BUILDING UPPER LEVEL HIGH IN THE SAME GENERAL
REGION. THERE WILL LIKELY BE A WEAK UPPER LEVEL TROUGH THAT
TRACKS 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 FLOW VELOCITIES EXPECTED. NO MAJOR SURGES OF
TROPICAL MOISTURE ARE EXPECTED OVER THE NEXT WEEK.
