Trade winds are expected to remain breezy through the week with lighter winds currently forecasted for the weekend. A gradual weakening trend is expected to start Thursday night. An area of deep tropical moisture is east-southeast of the state right now and expected to spread across Hawaii & Maui Counties affecting mainly the windward sides. Friday into the weekend we cannot yet rule out the possibility of an isolated thunderstorm or two. A front is expected to reach the islands early next week, pushing down the island chain to Hawaii County sometime late on Monday or early Tuesday. Ahead of the front winds will weaken and a diurnal land / sea breeze weather pattern will set up. That in combination with unstable conditions could spawn heavy showers Sunday afternoon. Will keep an eye on this scenario and bring you the updates.
