A cold front bringing maritime air from New England swept across Long Island Friday night, bearing along with it cooler-than-normal temperatures that will linger until Sunday, the National Weather Service said.

A few hit-and-miss showers may pop up Saturday evening, said meteorologist Bill Goodman, who works in the weather service’s Upton bureau, while a slight wind carries through the day.

“I think any heavy rain is going to be well west of Long Island today,” Goodman said.

Matt Hammer, a meteorologist with News 12 Long Island, said Saturday’s weather isn’t the best start to the weekend, with temperatures several degrees below the normal high of 82. The chance for showers or a thunderstorm increases later in the evening as well.

Temperatures will peak in the mid-70s Saturday, he said. In the evening, the thermometer will drop to about 65 or 70 degrees, with the East End a bit cooler and the western part of the Island a bit warmer.

For Sunday, “it looks like we’ll finally get out of this maritime air,” Goodman said, and temperatures are expected to reach 80 degrees with partly sunny skies.

An alert was issued Saturday morning warning of a moderate risk for rip currents along the southern shorelines in Suffolk and Nassau counties, as well as Brooklyn and Queens.

“There is a moderate risk of rip currents at Atlantic facing beaches,” the alert states. The risk is expected to dissipate on Sunday.

“Unless you like cool cloudy days at the beach, Sunday is the better day to go,” Goodman said.

No precipitation is in the forecast for Sunday, he said Saturday. “It looks like a good day tomorrow.”

Long Islanders felt the hottest temperature on Wednesday at 88 degrees, the most “uncomfortable” day this week when humidity was high, Goodman said. Tuesday and Thursday’s temperatures also ran close to that high, he said.

The workweek will start off with a “nice mix of sun and clouds,” Hammer said. The temperatures and humidity will rise again toward the end of the week with highs in the mid- to upper 80s.
