Long Island’s backyard chefs and beachgoers get a steady dose of sunshine for most of Independence Day, forecasters said.

“It’s another nice day,” News 12 meteorologist Bruce Avery said.

Clouds do increase later on Monday, and there’s chance for rain, some of it heavy, starting late Monday night and into Tuesday morning, Avery and the National Weather Service’s Upton office said.

Daily highs are in the low 80s, with winds at 8 to 13 mph shifting south.

Avery said it will be more humid than conditions the past couple of days, and that the heaviest of the rain is likely to develop after midnight.

He said localized flooding is possible and that the rain could linger into Tuesday’s morning commute.

The service said thunderstorms are possible, including as late as 11 a.m. Tuesday; new rainfall amounts could range between one-half and three-quarters of an inch.
