Breezy trade winds are expected to stick around through the weekend. Showers are forecast to continue moving across the islands during the next several days with rainfall focusing over windward and mauka areas. Some of the larger showers will reach leeward locations at times. 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. The Kona side will be partly cloudy to start and mostly cloudy with scattered showers each afternoon. Some of those showers may be heavy. High temperatures from 84° to 89°. Northeast winds from 15 to 25 mph.
