Looking Ahead 

Breezy conditions are expected through the end of the work week. Trade winds will push showers into our usual windward and mauka areas and some of that moisture may pass leeward from time to time. Over the weekend, winds are expected to shift and become light as our “natural air conditioner” – high pressure – moves away from the islands and a cold front approaches. The cold front is expected to move down the island chain from Kauai to the Big Island from Sunday through Tuesday.
