Looking Ahead
Trade winds are expected to slowly build from east to west across the state through Wednesday. The trades will then drop off Thursday and Friday as a front approaches from the northwest. Limited showers will favor windward and mauka areas through the week. A change in weather is expected over the weekend as a front pushes southward through the island chain, bringing an increase in showers and strong trade winds to the Aloha state.
