Trade winds will remain windy through the weekend. Showers will pass over windward and mauka areas, while also lingering over some leeward areas. Drier air should move in by Friday, followed by increased showers Saturday.


A cold front just north of Kauai will move SE and stall near Maui County and dissipate late today and tonight. Trade winds overrunning the front have arrived to the islands and push upstream clouds and showers across the islands over the next couple of days. #hiwx

Enhanced showers are expected today as a weak low level disturbance moves west across the state. Most showers will be over windward and mauka areas, with some lingering over leeward areas. Expect drier conditions tomorrow morning through mid week.


A low aloft will destabilize the island atmosphere this weekend, bringing the potential for some locally heavy showers and a chance for thunderstorms. Expect stronger trade winds to return next week.
