Forecasters say a trifecta of winter weather will likely hit New Jersey over the next few days. The National Weather Service has issued a winter storm warning for extreme northwestern areas, where anywhere from four to eight inches is expected to fall. The snow also could mix with sleet and freezing rain at times. Central and southern New Jersey could see between two and three inches of rain from the storm. A flood watch issued for those areas will likely be in effect through Thursday morning.
