    Looking Ahead

    Moisture from a trough near the Big Island will maintain cloudy and wet conditions over the eastern end of the state through the weekend. A drier light wind pattern is in place from Molokai to Kauai, so expect fewer showers to start the day. The moisture near the Big Island is expected to drift back toward the west today and Sunday as a potent upper level low drops over the state. The resulting unstable conditions will bring a threat of heavy, flooding showers and thunderstorms across much of the state through the Monday holiday.
