If Sunday could lead you to believe December on Long Island had been transported to a temperate oasis, Monday should bring a reality check.
Yes, we're looking at cold and rain, with a chance of snow. And expect the rest of the week to serve as a reminder that winter is not fleeting.
Joe Pollina, a meteorologist at the National Weather Service in Upton, said an arctic front will begin moving through the region Monday afternoon. Precipitation was anticipated to get a head start early Monday morning, and that rain could turn into snow flurries in the afternoon - though Pollina said he didn't expect there would be enough to coat the ground.
"We're not looking for any big storm out of this," Pollina said. "The main focus of the storm is up north."
The temperatures will stay cold the rest of the week, Pollina said, with highs in the 20s Tuesday and a possibility of a snowstorm by week's end.
"The models are hinting at something with snow later this week," he said. But, he added, "It's still very uncertain."
And, in case you were wondering how nice Sunday was: Upton recorded a high of 55 degrees - one week after it reported record snowfall of 26.3 inches.
