New York City – All of New York City was placed under a dense fog advisory early Monday as warmer air moved into the region following overnight freezing rain across the Tri-State Area. Weather officials warned that reduced visibility could affect the morning commute and travel throughout the region.
The dense fog advisory remained in effect until 12 p.m. Monday, extending beyond the city into parts of New York, New Jersey, and Connecticut.
Dense Fog Advisory Covers Multiple Counties
In addition to New York City, the advisory included Sullivan, Orange, Rockland, Putnam, and Westchester counties in New York; Sussex, Warren, Morris, Hunterdon, Somerset, Middlesex, Bergen, Passaic, Hudson, Union, and Essex counties in New Jersey; and Fairfield County in Connecticut.
Forecasters said the fog developed as warmer, moist air passed over colder ground left behind by overnight freezing rain, creating near-whiteout conditions in some areas during the morning hours.
Wind Advisory Issued for Parts of the Region
While fog reduced visibility, a separate wind advisory was also issued for much of New Jersey and Sullivan County, New York. The advisory runs from 10 a.m. Monday through 1 p.m. Tuesday, with wind gusts expected to reach 40 to 50 mph.
These strong winds are forecast to combine with falling temperatures, producing dangerous windchills as colder air moves back into the region.
Monday Forecast: Rain, Brief Warm-Up, Then a Sharp Cooldown
With warmer air briefly in place Monday morning, any lingering freezing rain transitioned to plain rain across all locations. Periods of rain may become heavy at times before tapering off during the afternoon.
Temperatures are expected to rise into the low 50s for a short time before skies begin to clear. The brief warm-up should melt remaining snow on the ground across much of the area.
Arctic Air and High Winds Return by Nightfall
Clearing skies Monday evening will signal the arrival of another surge of arctic air. As temperatures fall rapidly, strong winds will redevelop Monday night into Tuesday, with gusts again approaching 50 mph at times.
These conditions could drive windchills into the teens and even single digits, creating hazardous outdoor conditions.
Cold Pattern Expected to Persist Into 2026
Forecasters say the arctic air mass is expected to linger through the end of the week and into the start of 2026, keeping temperatures well below seasonal averages and maintaining the risk of harsh windchills across the region.
Residents are urged to use caution while driving in foggy conditions, secure loose outdoor items ahead of high winds, and prepare for a prolonged stretch of cold weather.
