Extreme cold tonight, then a snow and ice storm?
Dangerous cold and frigid wind chills are currently gripping the coverage area. This is the result of a chunk of the polar vortex moving south, and unloading tons of arctic air in the northeastern United States. Temperatures will continue to drop through the night and it shouldn't start warming up until around 8 AM tomorrow.
Highs tomorrow will range from the upper single digits to the low teens.
Monday will be a little bit warmer, with snow moving in around noon. Snow will pick up in intensity around 6 PM, as the rain/snow line of the storm approaches. The steady moderate to heavy snow won't last very long in New York City, where precipitation should switch over to rain around 8 PM. By Midnight I think the entire coverage area will be done with snow with some light rain falling. The rain will freeze upon contact in northwestern sections of the coverage area, on top of the 2-4 inches they had gotten earlier. Tuesday morning all frozen precipitation should change over to rain, and the rain could fall heavily around noon Tuesday.
Rain should start start to move out during the afternoon Tuesday, and should be of the area by nightfall.
Some decent snow accumulations are likely before the changeover to rain. As much as four inches is possible in northwestern New Jersey and Orange County.
The bigger concern will be ice. As much as a quarter inch of ice will fall in western portions of the coverage area, and some models are indicating even more could accumulate.
Another inch or two is possible Wednesday morning with a clipper system.
I don't see any big storms in the near future, and a warm up is likely between the 20th and the 25th. After the 25th a big cool down is likely, and March could start interesting.
