Looking Ahead

Light to moderate trade winds are expected until a disturbance moving over the islands starting Saturday weakens the trade winds and allows sea breezes to develop. This means afternoon clouds and showers are possible through early next week. The chase for locally heavy rain in the afternoon exists over the next couple of days. A front may move over the islands by the middle of next week with cool north winds behind it.

Weather models are showing Nora moving into the Central Pacific Saturday night and re-curving far southeast of the islands as the trough digs toward us. Still, we will keep an eye on this as it continues along its track.

Today and Sunday

Today we expect mostly cloudy skies with numerous showers for windward and mauka spots. The Kona side is forecast to start out mostly sunny with clouds building in the afternoon and scattered showers. Locally heavy rainfall is possible. High temperatures from 84° to 89°. Variable winds are forecast up to 15 mph.

UV index at 10 (“very high” exposure level)

Tonight and Sunday Night

Variable winds are expected in the evening up to 15 mph. Low temperatures from 74° to 79°. Mostly cloudy skies are expected in the evening with scattered showers until the land breeze takes hold and clears the clouds overnight.
