HONOLULU (KHON2) – Guidance has come into closer alignment today with the latest consensus showing the trough moving into Maui County by Sunday afternoon.
Expect an uptick in showers across windward Maui by Sunday evening, with the moisture plume spreading westward into Oahu and Kauai County Sunday night into Monday.
Rainfall totals through Monday will be around 0.5 to 1.0 inches across windward and mauka areas of the smaller islands.
With the moisture plume staying north of the Big Island rainfall totals across windward and mauka areas will generally be less than 0.5 inches.
The trough looks to exit the region towards the west on Tuesday, with high pressure quickly rebuilding across the area.
However, guidance now shows another moisture plume moving into the area on Wednesday which may bring an increase in clouds and showers to windward and mauka areas.
Otherwise, expect predominately dry and stable conditions to return for the latter half of the forecast period, with typical summertime conditions yielding limited clouds and showers across the state under moderate to breezy trades.
Small Craft Advisory until 6 PM HST Sunday for Kaiwi Channel, Maui County Windward Waters, Maui County Leeward Waters, Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Windward Waters, Big Island Leeward Waters, Big Island Southeast Waters.
