ARTICLE CONTINUES BELOW AD

We expect typical trade wind weather. Windward and mauka areas can expect on and off scattered showers and partly cloudy skies during the day. While the Kona side and coastline should have a mostly clear morning before clouds begin to build in the afternoon. The UHSOEST vog model is predicting voggy conditions in Kona and through the area to South Point in the afternoon as the sea breeze pushes the haze back up onto the leeward side. High temperatures should fall in the range of 81° to 86° and around 71° at 5000 feet. In general, trade winds up to 10 to 25 mph are expected.

Looking Ahead

Our current cool, dry trade wind weather conditions are expected to hold through tomorrow. Trade winds are expected to remain breezy through the week with lighter winds currently forecasted for the weekend. Thursday unstable conditions could spawn enhanced showers for Hawaii County. Friday into the weekend there’s the possibility for isolated thunderstorms. Will keep an eye on it and bring you the latest model consensus.
