Breezy trade winds are expected into next week. While clouds and showers will primarily affect windward coasts and slopes, winds will be strong enough to push showers to leeward areas from time to time. Daytime heating will cause clouds and showers to develop over the Kona slopes each afternoon.
We expect partly to mostly cloudy skies for windward Big Island with showers likely in the morning and scattered showers in the during the day. The Kona side will be partly cloudy to start and mostly cloudy with isolated showers each afternoon. High temperatures from 87° to 92°. Northeast winds from 15 to 20 mph.
