Looking Ahead
Trade winds are expected to continue through the weekend and into next week. Brief passing showers will ride on our winds and push into windward coasts and slopes over the next couple of days, with no major moisture sources expected. A disturbance high in the atmosphere will continue to support the development of locally heavy showers over leeward Big Island the next couple of afternoons, but is otherwise expected to have little effect on island weather through the weekend. Increased moisture is expected to fuel a greater number of windward showers early next week.
Today
Today we expect mostly cloudy skies for windward Big Island in the morning with showers likely and partly cloudy skies and scattered showers in the afternoon. The Kona side will be clear to start and mostly cloudy with showers likely each afternoon. Some of those showers may be heavy. High temperatures from 84° to 89°. Northeast winds are expected from 10 to 20 mph.
UV index at 11 (“extreme” exposure level)
Tonight
Northeast winds are expected this evening from 10 to 20 mph. Low temperatures from 73° to 78°. Mostly cloudy skies are expected in the evening with scattered showers for windward spots. Leeward spots should get scattered showers in the evening with a clearing trend as the night goes on.
