Looking Ahead

Unsettled weather will persist over the eastern end of the state today with possible heavy showers and a slight chance of thunderstorms as an upper level trough passes over the island chain. Weather conditions are expected to finally improve on the Big Island tonight as a more stable airmass spread to that area, with trade wind weather returning. The rest of the state will see breezy trade wind weather through the week as a strong surface high far northwest advances east.
