Long Island weather: Cool, with rain late in the day

Mother Nature’s plans for Wednesday and Friday — but not Thursday — include some light rain, mostly toward the end of the day and evening, the National Weather Service in Islip said.

There is an 80% chance of showers after 4 p.m. Wednesday, forecasters said. A coastal flood advisory is in effect for southern Nassau from 7 to 11 p.m., with "widespread minor to locally moderate flooding" expected near the waterfront and shoreline, the weather service said.

"Temperatures will remain below normal through the period, with highs today in the 50s and in the lower and middle 60s on Thursday," the weather service said.

The sun should rule Thursday, the weather service said, though nighttime clouds could bring rain on Friday. The odds of precipitation are 50% after 2 p.m.

The high for Friday will be in the low 60s, and while both Saturday and Sunday will be at least partly sunny, the weekend will be cooler — likely around the mid-50s.

There is a 40% chance some downpours will be seen on Monday. Tuesday, however, appears bright and clear, the weather service sad. The high both days is expected to be in the upper 50s.
