Long Islanders can look forward to a nice sunny and dry day Sunday to end their July Fourth weekend celebrations, though rain could put a damper on things for much of the week ahead, according to the National Weather Service.

"It'll be a nice dry day," Brian Ciemnecki, meteorologist for the National Weather Service at Upton, said about Sunday. Highs will be in the lower 80s and lows will be in the mid- to upper 60s.

"On Monday there'll be some patchy fog, but for the most part it'll be another nice sunny day," Ciemnecki said. Highs again will be in the lower 80s and lows will be in the upper 60s. And the first chance of showers arrives.

"There's a slight chance of showers, primarily after midnight," Ciemnecki said.

"Tuesday looks like a better shot of showers and maybe an isolated thunderstorm," Ciemnecki said, but there will be a silver lining in those clouds. "On Tuesday it'll finally feel like summer around here," he said. Highs will be in the lower to mid-80s and lows will be in the 70s.

A chance of an afternoon shower or thunderstorm comes on Wednesday, when highs will be in the mid-80s and lows will be in the upper 60s.

For the start of the weekend on Friday look forward to a sunny and dry day with highs in the lower 80s and lows in the upper 60s.
