If Long Island has a white Christmas, it will be from snow already on the ground.
And Saturday is likely to be wet and windy.
For Christmas, it will be cloudy with patchy fog lingering in the morning and a 30 percent chance of rain in the afternoon, with highs in the upper 30s. "We're going to be warm enough across Nassau and Suffolk for this to be rain," Murray said.
Friday night the chance of rain will increase to 60 percent after midnight and winds will increase to 15 to 20 mph. The lows will be in the upper 30s.
On Saturday, the chance of rain bumps up to 80 percent and remains that way through the evening. It will also be windy, with highs in the lower 40s. Saturday night the lows will be in the upper 30s.
"There will be considerable melting of snow and it will be slushy," Murray said, but he expects some of the snow on the ground to outlast the rain.
"On Sunday, dry conditions return," Murray said.
