The first snowstorm of 2012 is impacting North Jersey on Saturday, while here in South Jersey rain has washed away most of an overnight dusting. The National Weather Service says a trace amount of snow fell in Cape May County on Saturday before the changeover to rain took place. Meanwhile, North Jersey counties are expected to see between three to five inches of snow on Saturday. It all will melt quickly as Monday’s temperatures will flirt with 60 degrees.
