HONOLULU (HawaiiNewsNow) - Long-absent trade winds are returning to the Hawaiian Islands, but a lingering disturbance could still bring more thunderstorms and locally heavy rain to parts of the state for Memorial Day.
The returning trades are moving in beneath an unseasonably strong upper level low pressure system that caused Sunday's heavy rains and thundershowers on Kauai and Oahu.
The National Weather Service said the disturbance could keep the trade winds on the light side for Kauai and Oahu, but it also could bring the threat of afternoon showers and thunderstorms for leeward areas of the islands, including the Waianae mountains and parts of Leeward Oahu, as well as interior and summit areas of the Big Island of Hawaii.
Trade wind showers may also be heavier than normal for windward areas of all the islands.
The bottom line is that we'll have a transitional day with wetter than normal trade wind weather and the possibility of afternoon convective showers for leeward areas.
Trade winds should firm up Tuesday as the upper level low continues drifting eastward and departs the islands, and weather should return a bit closer to normal.
