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.
