NORTH JERSEY - In anticipation of winter weather, the National Weather Service in New York has issued a Hazardous Weather Outlook for Thursday, Jan. 17,  through Tuesday, Jan 22.

A triple threat of winter weather will impact the North Jersey area over the next several days, providing the year’s first snowfall and potentially the coldest temperatures of the season. The line-up begins with a fast moving winter storm Thursday night, Jan. 17. This system, the remnants of a low-pressure system moving east out of the southern plains, is expected to drop 1 to 3 inches of snow over most of New Jersey. Current model guidance is in agreement that the heaviest precipitation is likely to fall sometime around 4 a.m. to 5 a.m. Friday morning.

The setup of the first storm will shape the trajectory of the second storm, a nor’easter expected to evolve from a low-pressure system moving out of the Midwest. All model guidance agrees that the nor’easter will impact North Jersey Saturday night through Sunday, but snowfall totals remain highly uncertain. As of Wednesday, Jan. 16, the midday run of the Euro model predicted around 10 to 12 inches for North Jersey, while the American GFS model indicated a range of 3 to 8 inches in the last two iterations. The uncertainty stems from fluctuations in the timing and location of a mix line, which will set up along a southwest to northeast axis roughly paralleling Interstate 95—areas west will receive snow, while areas east will receive rain. A track shift of +/- 20 miles will result in extreme differences in snowfall totals across North Jersey.

The passage of the second storm will coincide with a tongue of Arctic air moving down into the Northeast from Canada. The mercury in North Jersey could fall as low as -1 degree Fahrenheit by 7 a.m. Monday morning, Jan. 21. Factoring in wind chill (15 mph wind), temperatures will feel like 20 below zero. The high Monday is not expected to rise above 14, and caution is urged if performing any outdoor activities. During the morning, temperatures will be low enough (and winds high enough) to induce frostbite on exposed skin in under 30 minutes.
