Looking Ahead

ARTICLE CONTINUES BELOW AD

A moist air mass is sticking around this weekend so the possibility of heavy rain and thunderstorms also lingers. Trade winds are expected to replace our light and variable winds by Monday. Clouds and showers are forecasted to diminish overall during mid-week, but also will become more focused along windward slopes. Unsettled weather may return for next weekend.
