Looking Ahead
High pressure far to the north will build back in across the region today with breezy trade winds returning to the islands through next week. An upper level trough over the Big Island today will enhance shower activity and produce isolated thunderstorms in the afternoon. Elsewhere most leeward locations will see fair weather conditions with more typical windward and mauka clouds and showers developing along northeast slopes of all islands. These northeast trade winds will continue to push volcanic emissions from the Kilauea volcano towards the southwest, away from the rest of the state. High confidence remains in our long range trade wind forecast through the end of next week.
