Rain is expected Saturday, the first day of the holiday weekend, but by late Sunday morning the skies over Long Island should clear and Monday looks to be a great day to go outside to celebrate Independence Day.

Overnight Friday into Saturday there is a 40% chance of showers and thunderstorms, mainly after 2 a.m. Gusts as high as 30 mph were expected, the National Weather Service said Friday evening.

Saturday will bring showers and possibly thunderstorms, the weather service said. Storms could bring gusty winds and heavy rain. The predicted high temperature is around 81 degrees and the chance of precipitation is 80%.

The weather service warned that life-threatening ocean rip currents are likely Saturday all along the South Shore of Long Island. 

"Rip currents can sweep even the best swimmers away from shore into deeper water," the service said.

Sunday has a 30% chance of showers before 8 a.m. before the skies should clear and the temperature reaches a high of about 83 degrees.

The forecast for Monday, July 4th, is simple: sunny skies and a high temperature near 80 degrees.

When the shortened workweek starts Tuesday there is a 40% of showers. Wednesday, Thursday and Friday are all expected to be mostly sunny.

High temperatures Tuesday through Friday will range from about 78 to about 80 degrees, the weather service said.
