Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
340 AM EDT Sun May 19 2024

Valid 00Z Mon May 20 2024 - 00Z Mon May 27 2024

A deep Kona low north-northwest of Hawaii should weaken as it
lifts north Sunday-Monday, but another shortwave/upper low will
drop in to the northwest of the islands behind it before weakening
later in the week. Despite these active systems, the heaviest
rainfall should remain west of the main islands, though some more
organized showers may continue this weekend across Kauai. Trades
should return to a more easterly direction after Sunday, with
mainly a windward and sea breeze focus for showers through the
week, as upper ridging and surface high pressure build back in to
the north of Hawaii and lasting through at least next weekend.
