Today

Today windward spots are expected to be mostly cloudy with numerous showers. The Kona side is forecasted to get morning sunshine and afternoon cloud cover. Hazy skies are expected for much of the Big Island (see UHSOEST vog model above). The rain will help to clear some of that vog out. Variable winds are forecasted from 10 to 15 mph. In the afternoon winds are expected to shift out of the northeast around 15 mph. High temperatures should fall in the range of 78° to 83°.

Sunday

Windward spots are expected to be mostly cloudy with numerous showers. The Kona side is forecasted to get partly cloudy skies and isolated showers. Winds are expected out of the east around 15 mph. High temperatures from 79° to 85° and low temperatures from 68° to 73°.

 

Looking Ahead 

A weakening front is forecasted to stall and dissipate near the Big Island on Saturday. Strong winds are expected to continue over the Big Island summits. Remnant moisture from the old front will be drawn back northwest across the state Sunday through Monday as another front stalls several hundred miles northwest of Kauai. Drier trade wind weather is expected during the middle of next week. A front slowly approaching from the northwest and tropical moisture approaching from the southeast may bring unsettled weather to the state by late next week.
