Looking Ahead

High pressure to the north and ridging aloft will maintain a stable trade wind flow through Sunday with clouds and showers favoring the windward and mountain areas. A surface low forming northwest of Kauai in the next 24 hours will cause the winds to blow out of the southeast and south starting Sunday. This flow will bring in not only some humid weather but the potential for some unsettled weather to the western end of the island chain that may last through the first half of the new week.
