Another warm and humid day, but with no rain, is ahead for Saturday, which starts with clouds and patchy fog that will give way to breaks of sunshine in the afternoon, forecasters say.

“Today will be a nice day across Long Island,” News 12 Long Island meteorologist Matt Hammer said of Saturday. He said temperatures in most areas will be in the mid to upper 70s with the East End seeing temperatures in the low 70s.

“We’re going to be at least 10 degrees higher [on most parts of the Island] Saturday,” said Tim Morrin, a meteorologist with the National Weather Service’s Upton office. “That’s due to a ridge of high pressure over the Eastern Seaboard that’s conducive for warm weather.”

Morrin said the normal high at Islip is 66 and the normal low 49.

Hammer said the high will be 79 in Westbury, 78 in Merrick, 77 in Northport, Coram and Babylon, and 74 in Sag Harbor and New Suffolk.

Some clouds will linger through Saturday evening, but it was expected to be dry until after midnight. The overnight low will be near 66.

A small craft advisory will be in effect from 6 a.m. to 6 p.m. Sunday, when it will be mostly cloudy with scattered showers and highs around 76 degrees and lows around 66.

Hammer said there could be some downpours on Sunday “tapping into a little bit of Nate,” but he said that on Monday he’ll start to track any significant impact from Nate on Long Island. He said that as of Saturday morning, Nate was a Category 1 storm that was likely to impact the Gulf Coast late Saturday night into early Sunday.

“We could see remnant rain showers as we look to late Monday into Tuesday,” Hammer said. But, he added, the “bulk of the rain could stay just to our north and west,” meaning mostly dry conditions during the daylight hours for those Columbus Day parades and other holiday activities outdoors.
