The weather service's regional forecast said a high pressure system will slide offshore Sunday and "a series of waves of low pressure [will] move along a frontal boundary to the south Monday through Tuesday night."
The workweek on Long Island will start Monday with partly sunny skies and a 20% chance of showers after 2 p.m. while Tuesday will be mostly cloudy with a 40% chance of precipitation and Wednesday will be partly sunny with a 30% chance of rain, according to the weather service.
