HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
313 AM EDT WED SEP 11 2024
VALID 00Z THU SEP 12 2024 - 00Z THU SEP 19 2024
THE UPPER LOW CURRENTLY SITUATED NORTH OF HAWAII SHOULD SLOWLY
WEAKEN AND THEN DRIFT TO THE SOUTHWEST THROUGH THE END OF THE
WEEK, AND THE ASSOCIATED SURFACE LOW SHOULD EVOLVE INTO AN
INVERTED TROUGH AXIS BASED ON THE LATEST GUIDANCE. THERE IS GOOD
MODEL AGREEMENT THAT THE MAIN SURFACE HIGH NEAR 40 DEGREES NORTH
BUILDS BACK IN BY EARLY NEXT WEEK.
THE LIGHT AND MORE VARIABLE FLOW CURRENTLY IN PLACE ACROSS THE
ISLANDS IS EXPECTED TO GIVE WAY TO MORE STEADY EAST-NORTHEASTERLY
FLOW BY THE END OF THE WEEK WITH THE SURFACE HIGH REBUILDING
NORTH OF THE STATE. THE MAINLY TERRAIN FAVORED SHOWERS CAN BE
EXPECTED MOST DAYS, BUT NO MAJOR RAINFALL EVENTS ARE CURRENTLY
ANTICIPATED OVER THE UPCOMING WEEK WITH THE DEEPEST TROPICAL
MOISTURE REMAINING WELL TO THE SOUTH, ALTHOUGH THERE MAY BE SOME
RESURGENCE OF HIGHER PWS BY NEXT TUESDAY.
