Fire Island (FI) and NYC Weather

🌤️ Weather Forecast – January 23, 2026 (1 PM)

Cold air is starting to drain into the region today, and by tonight it will be frigid.

The next system will be a major storm, as a powerful system from the southwest brings heavy snow and significant accumulations to our area. There is a chance of mixing with sleet and freezing rain in NYC, and possibly even a brief change to rain on Fire Island. Even if mixing occurs, a significant snowfall (6”+) still looks likely.

Areas north and west of the city, much of Pennsylvania, Upstate NY, and New England will likely see 12”+.

This storm will be a major news-maker, bringing stormy weather to a large portion of the nation. Following the storm, even more frigid air moves in and lasts through next week.
