Tonight
ARTICLE CONTINUES BELOW AD
Mostly cloudy skies are expected tonight with scattered windward showers. Partly cloudy for leeward spots with isolated showers. Hazy skies will stick around. Northeast winds are forecasted from 15 to 25 mph. Low temperatures from 69° to 74° are expected.
Looking Ahead
A slow-moving front is spreading modest rain from the Kaiwi Channel to the Big Island through Monday night. Light southerly winds ahead of the front are forecasted to turn into breezy trade winds behind it. As the frontal cloud band falls apart, much of the moisture is expected to get caught in the trade winds. The winds in turn are expected to carry this moist air mass over the state again, bringing rainfall over windward slopes. Lee areas should experience some drying by mid-week, but a few showers will continue to drift leeward before dissipating. Conditions are expected to remain on the wet side of usual through the forecast period.
