Looking Ahead
Trade winds will continue to weaken, with showers remaining focused over windward slopes through early Wednesday. Widespread afternoon sea breezes are expected to trigger isolated heavy downpours on Wednesday, mainly over interior and mauka sections, as the atmosphere becomes increasingly unstable. A more stable but humid, hybrid trade wind and weak afternoon convective pattern will prevail on Thursday, followed by light and variable winds and a land and sea breeze weather regime heading into the weekend.

We expect sunny skies in the morning with mostly cloudy skies and showers likely in the afternoon for the Kona side. Thunderstorms are also a possibility. Partly cloudy skies are expected for the Hilo side with scattered showers. Winds are out of the east around 15 mph. High temperatures from 81° to 86°.
