Tonight
Southeastern facing slopes are expected to get scattered showers tonight and mostly cloudy skies. Leeward spots are forecasted to be partly cloudy with just isolated showers in the evening before clearing. East to southeast winds are forecasted from 10 to 20 mph. Low temperatures from 67° to 72° are expected.
Looking Ahead
A front is approaching from the northwest. Locally breezy southeast winds ahead of the front should focus showers over southeast areas of the islands and carry volcanic haze over the smaller islands. A band of showers along the front is expected to reach Kauai Saturday evening reaching Big Island around Monday night. Behind the front we expect breezy trade winds and showery weather for windward areas early next week.
