remember that clipper storm more then a decade ago that dove all the way to south carolina then rapidly intensified to a blizzard and produced close to 40 inches on eastern long island nyc only got about 10 inches we need that kind of clipper..
accuweather was wrong for days they predicted 4 to 8 for the city and said if the sleet is delayed we could get a foot for the city.. the sleet was not delayed any nyc reached over a foot..
many years ago in nyc like 15 at least we had a 12 hour sleet storm in nyc temps in low 20's and nothing but sleet covered the sidewalks and streets and everything was covered in ice and very slippery..
