Smoke from fireworks could linger over Oahu tonight until winds pick up sometime in the overnight hours, National Weather Service forecasters say.

Light, variable sea breezes are making for a cloudy and slightly humid last afternoon of the year, with isolated showers.

A cold front moving over Kauai should reach Oahu sometime after midnight, said Bob Burke, a meteorologist with the Honolulu National Weather Service office. 

The front should bring some light showers, mostly on the northeast slopes of the Koolau and Waianae mountains, such as Waialua and Kahuku, overnight and a change in the winds as the front passes on.

The usual trade wind weather should return to Oahu sometime on New Year’s Day.

Big wave surfers will also have something to celebrate on New Year’s Day. Burke said a reinforcement swell will keep waves at high surf warning heights through much of the day.
