Rain could somewhat mar parts of Saturday, the first day of the long Fourth of July weekend.

But from later Sunday morning on, expect sunny or mostly sunny skies, with temperatures in the 80s, forecasters said Friday afternoon.

Saturday was expected to start out with some sun and clouds, with the chances of scattered showers and thunderstorms increasing in the afternoon and evening, the National Weather Service said in its regional summary. Those showers and storms become increasingly likely for the overnight hours.

The weekend starts with humid conditions, but the weather service says a front moving through Sunday should lead to drier and less muggy weather.

Sunday morning could see showers, but they could give way to partly sunny skies, with highs heading up to the mid-to-high 80s.

Both Monday and Tuesday — Independence Day — are forecast to be sunny or mostly sunny, with highs in the low 80s.

The weekend was looking to start out “warm and humid,” said Rich Hoffman, News 12 Long Island meteorologist. Some spotty showers and thunderstorms could be in the picture, but we’re not talking about any washout, he said, “and you will be able to get some beach time.”
