Looking Ahead

A weak front will stall and diminish over and around the Big Island through tonight. Showers associated with the front will favor northern and windward sections of the islands today, then potentially linger over the eastern end of the state into Thursday as the boundary stalls. Gusty northerly winds along with drier and cooler air will fill in across the western end of the state through Thursday. A return of a more typical trade wind pattern is expected Friday into the upcoming weekend. Increasing rainfall chances will become a possibility early next week as another front approaches.
