    Looking Ahead

    A series of highs moving by to the north of the state will maintain moderate to breezy trades through early next week. A typical trade wind shower pattern is expected through Wednesday with windward and mauka areas being the primary targets. Deep moisture will increase as an old front sags southward into the islands Wednesday night through Friday, while an upper level trough passes overhead. This is expected to result in an increase in shower activity across the entire state, with some locally heavy rainfall and thunderstorms possible Thursday and Thursday night. Deep moisture will begin to decrease Friday night as the upper trough and old frontal remnants shift south of the area, with a more typical trade wind pattern returning over the weekend into early next week.
