Long Island will get drenched with about an inch of rain on Sunday, heading up a week filled with cold, uncertain weather.
Rain will begin to overtake the area by midmorning, becoming moderate to heavy in the afternoon, according to David Stark, meteorologist in the National Weather Service's Upton bureau.
There's no concern about all that water turning to ice, though. Highs will be in the 40s, with lows in the mid-30s.
The rain is slated to end before midnight. With the end of the rain, a cold front will muscle in pushing temperatures down for the rest of the week.
Monday will be dry and mostly sunny, with highs from 38 to 40 degrees, while Tuesday's high will be right at freezing, with cloudy skies and dry conditions.
Tuesday night, New Year's Eve, will see lows in the 20s with the wind chill making it feel more like the teens, Stark said.
Wednesday, the first day of 2014, will start out with a high of 30 degrees and a small chance of flurries. A developing system Wednesday night into Thursday could bring a chance of snow, but it's too early to say, Stark said.
Thursday could also bring a wintry mix to the area, with high temperatures right around freezing, Stark said.
Friday is set to be very cold, with the high around 25 degrees.
