Looking Ahead

High pressure north of the state will keep a moderate to breezy trade wind flow in place through the weekend, before strengthening to locally windy levels for the first half of next week. A band of an enhanced clouds and showers associated with an old front combined with an upper level trough moving through the state, will keep showery weather and abundant cloud cover in place through Friday, particularly over windward areas. Some of the showers may be heavy at times and an isolated thunderstorm can’t be entirely ruled out. A more typical trade wind pattern will return Friday night through the middle of next week, with showers favoring windward and mauka areas.
