Saturday will have fall-like, cloudy conditions again before sunny skies and above-normal temperatures return on Sunday, forecasters said.
A high-pressure system moving offshore through Saturday will keep cloudy and cool conditions on Long Island, according to Melissa DiSpigna, a meteorologist with the National Weather Service in Upton.
The high temperature is expected to be 67, with a low overnight of 61, said News 12 Long Island meteorologist Bruce Avery.
"A very nice, crisp fall day," Avery said.
The weather service issued a small craft advisory for seas of 4 feet to 7 feet off the South Shore until 6 a.m. Sunday. On Sunday, winds blowing from south to north will bring warm air and move the clouds, DiSpigna said.
Sunday's high is predicted to be 78, with a low of 67 and showers possible overnight, Avery said.
The normal temperature this time of year is 66 degrees, DiSpigna said.
Monday's Columbus Day holiday is expected to be mostly cloudy with a high of 72 and a low of 65, according to Avery.
Tuesday and Wednesday are forecast to have lots of sun, with highs in the upper 70s and lows in the upper 60s, Avery said. Thursday and Friday could see showers and thunderstorms with highs in the low to mid-70s and lows in the 60s.
