A winter storm is poised to strike New York City early next week — with an early forecast of four inches on the Big Apple, according to forecasts.

Snow and sleet will likely begin falling Monday as the mid-Atlantic storm rolls east and intensifies, according to experts who said the weather “raises alarm bells.”

“Every few years, a more notable threat comes around — one that draws the attention of meteorologists and rings a few extra alarm bells. That’s this storm,” according to New York Metro Weather forecasters. “[It] checks several of the boxes that we often look for when considering a high impact winter weather event.”

The site adds, “This will allow snow to spread into the Mid-Atlantic and New England on Monday … the potential exists for a long duration and high impact winter storm somewhere in the Mid-Atlantic and Northeast states.”

Temperatures on Monday are expected to hit a low of 32 degrees in New York City but the icy blast is expected to taper off on Tuesday, which has a forecast of “possible snow” and a low of 28 degrees, according to AccuWeather.

Wednesday will be partly sunny with a low of 26 degrees and a high of 36 degrees, according to the site.
