2019’s first major winter weather event has now triggered Winter Storm Warnings throughout the NYC Metropolitan Area. Recent runs of short range computer models have indicated larger-than-expected snow accumulations north and west of the city, with some places potentially receiving upwards of 12 inches of snow along with up to a quarter of an inch of ice.
While more areas may see more snow than ice or rain, the potential still exists for upwards of a quarter of an inch of ice to accumulate by early Sunday morning. The threat of ice, along with heavy snow and wind gusts potentially exceeding 50 mph, may lead to downed trees and tree limbs as well as power outages come Sunday afternoon. Coupled with sub-zero temperatures Sunday night, the storm has become potentially serious, especially for those who do experience lapses in electricity.
Along with the threat for downed trees and power lines also comes the threat for dangerous road conditions. Roadways will begin deteriorating late Saturday afternoon and, due to the rapid refreezing of any liquid on the ground going into Sunday night, will remain potentially hazardous at least through Monday morning.

Aside from several inches in November, it has been ten months since there has been significant snowfall seen in the New York City Metropolitan Area. This is now expected to change as soon as this weekend, as a significant winter weather event has begun to move east.
Snow will quickly develop and intensify as it moves into the Tri-State Area late Saturday evening or early Sunday morning, bringing with it rapid accumulations on most surfaces. However, the position of the storm will dictate if and when many locations will see a changeover to sleet, ice, or rain.
At the moment, it appears that locations north of the city and I-95 will experience this transition as early as 9 am Sunday, allowing for potentially significant ice accretions on many surfaces by noon Sunday.
Whether or not the precipitation remains frozen or becomes rain during the day, snow and ice will redevelop by the afternoon as temperatures drop and winds increase Sunday night. It is also important to note that, regardless of the direct impacts of the storm, temperatures will fall to near below zero throughout the Mid Atlantic and New England by early Monday morning. This rapid refreezing could mean any liquid precipitation that falls may become ice on roads, trees, and power lines quickly after the storm exits the area.
Due to the uncertain nature of the this storm, Weather 360 is currently forecasting anywhere between 4 and 12+ inches north of I-95, with anywhere between 3 and 8+ inches to its east and south. Forecasts will be refined in the coming days as the center of the storm develops, but for now, be prepared for a storm that could knock out power, make travel dangerous for an extended period of time, and dump a significant amount of snow, sleet, ice, and rain.
A significant winter storm has brought up to 12 inches or more of snow along with wind gusts exceeding 60 mph to the Northeast. Schools remain closed throughout southern New York, New Jersey, and Connecticut as wind speeds of 40 mph create wind chills approaching 25 below zero. The National Weather Service has issued wind chill advisories for the area warning of the potential for frostbite to occur within 30 minutes of exposure to the record-breaking low temperatures.
Expect high winds to continue to create low visibility going into Friday afternoon with the potential for downed trees and tree limbs lasting until Sunday morning.
