Looking Ahead
An area of low pressure far northwest of Kauai, will lift northeastward today through early in the work week, dragging a weakening front toward the islands. Deep tropical moisture and showers associated with the front will overspread the western end of the state Monday night into Tuesday and linger through the middle of the week as the front stalls just northwest of Kauai. Hot and muggy conditions can also be expected across much of the island chain as winds shift around to the south and southeast ahead of the front. A more typical trade wind weather pattern is expected to return by late in the work week as high pressure builds back in to the north of the islands.
