Tonight 

ARTICLE CONTINUES BELOW AD

For leeward areas, mostly cloudy skies are expected tonight to start with clearing expected through the night as the land breeze takes hold. Variable winds are forecasted from 5 to 15 mph. Low temperatures from 70° to 75° are expected.

 

Looking Ahead 

Light winds are expected across the state through mid week, allowing localized land and sea breezes. A disturbance high in the atmosphere is expected to pass over the islands and may help to enhance showers through the middle of the week. The lighter winds will bring a greater chance of afternoon clouds and showers over leeward and interior portions of all islands. Trade winds will slowly strengthen during the second half of the week, with showers once again focused over windward areas.
