Long Islanders will be spared the snow and ice that is expected to develop across portions of the eastern seaboard over the next day or so, the National Weather Service said.
A few flakes mixed with rain have been spotted in various pockets on the Island, but temperatures rose above 38 degrees in the afternoon, scratching out chances of snow accumulation, said meteorologist David Stark in the service's Upton office.
Temperatures will continue to rise into the evening, when commuters will see spotty rain and drizzle, the service said.
A cold front with northeast winds from 13 to 15 mph had helped drop temperatures nearly 20 degrees after a Monday in the low 60s, the service said.
The precipitation delayed arriving flights at LaGuardia Airport by more than an hour in the early evening and by almost an hour at Kennedy, according to the Federal Aviation Administration website.
The agency was advising travelers to check with their airlines to determine whether their flights are affected.
In a relief from the chill, warm air moving up from the ocean will ride over a thin layer of cold air that is hovering close to the ground.
That paves the way for something unusual -- temperatures rising instead falling as the night goes on, Stark said.
After midnight, the warmer ocean air will push temperatures from the 40s to low 50s, Stark said.
Localized coastal flooding is possible, especially at times of high tide, through Wednesday morning along the western shores of the Long Island Sound, the service said.
The Wednesday morning commute is expected to be a repeat of Tuesday's evening commute, he said: "It'll just be that cloudy, damp, gray kind of day."
By Thursday, sunny skies develop as daytime temperatures climb to the mid 40s, with northwest winds between 7 and 11 mph.
