Long Islanders can look forward to warmer than normal temperatures on Sunday, which forecasters say will be a preview for more mild weather later in the week beginning on Tuesday.

Carlie Buccola, a meteorologist with the National Weather Service in Upton, said: “There’s a warm front that came through yesterday (Saturday) bringing warmer air.”

News 12 meteorologist Bruce Avery said luckily that warm front will be hanging around despite some predicted precipitation.

“We had a beautiful day on Saturday,” Avery said. “Overall I think we’re going to squeeze in a decent Sunday,” he said, though clouds are expected to increase in the mid to late afternoon.

The high Sunday will reach at least 68 degrees in most areas — well above the normal of 59 — but showers are expected by the evening when the low will be a cooler 45.

Avery said it will be 68 in Babylon, Coram, Southold and Amagansett, but the mercury will climb to 69 in Commack and reach an even warmer 70 in Hicksville and Baldwin.

Avery attributed the rain to shower activity originating in the Great Lakes.

A mix of sun and clouds is expected when Halloween arrives on Monday. Highs only near 54 and lows near 40 are expected.

“There’ll be a lot of sunshine on Halloween but it will be significantly less warm,” Avery said.

Another sun and clouds mix is ahead for Tuesday when temperatures will begin to climb again and highs will be near 60 and lows near 49.

More sun and clouds are forecast for Wednesday when things warm up quite a bit with highs near 68 and lows near 53.

Mixed sun and clouds return for Thursday when there will be late-day showers and highs will climb to near 69 and lows near 50 are expected.

Partly sunny skies will start the weekend on Friday but temperatures will drop. Expect highs near 58 and lows near 42.
