Showers late Sunday herald unsettled week

Light showers and even some thunderstorms are a possibility Sunday night, according to the National Weather Service -- and more wet weather could be in store for the rest of the week as well.

While most of Sunday will feature sunny skies with highs in the middle to upper 70s, Sunday night brings a chance of light precipitation, meteorologist Joey Picca said.

Lows on Sunday will be in the middle to upper 50s, he said.

An upper-level, low-pressure system will keep the weather unsettled for much of the week, Picca said. Monday and Tuesday bring scattered precipitation across Long Island, with highs in the 60s and lows in the 50s. Picca said the weather system appears to be settling in the area until next weekend. Cloud cover during the week will keep temperatures down slightly below the average for this time of year, he said.

A coastal flood advisory has been issued for Sunday night for low areas along the Sound that are prone to flooding, Picca said. The advisory, which is in place for 6 to 10 p.m., is due to slightly higher than normal tides coupled with winds, he said.
