Long Islanders might want to keep a jacket on hand for Sunday and much of the week to brace for some cool weather ahead.

“It’s going to be a chilly week until it gets towards the end,” warned News 12 Long Island meteorologist Bruce Avery.

Saturday’s fierce winds will dissipate a bit by Sunday, with a wind advisory being lifted by 6 a.m., though it will remain windy with gusts from 30 to 40 miles per hour.

Sunday motorists are also advised to look out for downed trees and wet leaves that might cause slick roadways.

John Murray, a meteorologist for the National Weather Service at Islip, said rainfall on Long Island for Friday and Saturday ranged from a quarter-inch in some areas to almost two inches. He noted that in Orient 1.79 inches of rain fell.

“There still may be leaves that have fallen to the ground during Saturday’s wind and rain, so in some spots the ground could still be moist and slippery.”

On a brighter note it will be mostly sunny Sunday with highs of 60 degrees in many areas, but clouds will increase at night when showers are possible and a low of 48 is expected.

Avery predicted a Sunday high of 59 on the East End in Amagansett and Southold, and said the temperatures will reach 60 in Coram and Babylon, 61 in Commack and 62 in Hicksville.

Showers are possible on Monday but they should be clear out before the morning commuter traffic gets really heavy. Any rain is forecast for between 4 a.m. and 7 a.m., and mostly sunny skies are forecast for the afternoon.

Highs on Monday will be near 62 — two degrees higher than normal — but it will be breezy with 10 mph winds. At night it will be mostly clear but chilly with lows around 41 with some much colder 30s in the pine barrens.

Mostly sunny skies hang around for Tuesday when highs of only near 53 are predicted. Tuesday night will be partly to mostly clear but cold with lows around 36, with temperatures dropping to the low 30s in the pine barrens.

Another day of mostly sunny skies comes on Wednesday when it will remain cool with highs near 54 and at night some clouds come in, bringing with them chilly weather with lows ranging from 38 to 43.

Clouds will increase on Thursday when highs near 57 and lows around 42 are forecast.

A gloomy start to the weekend is ahead for Friday when it will be cloudy with periods of rain and highs will be near 59. At night any rain is expected to end and lows are predicted of near 45. But then temperatures should become milder.
