Looking Ahead

Locally breezy trade winds are expected through the weekend. The trades will push clouds and some showers over windward areas, but stable conditions are forecast so rainfall amounts will be light. Winds will weaken and shift out of the south next week as a front approaches from the northwest. Shower activity will increase as the atmosphere become more moist and unstable.
