According to the National Weather Service, some areas could see scattered frost. Interesting, because the forecast low temperature seems pretty consistent in Southern NJ (~37 degrees). No frost warning when I look at Port Republic, Bass River or Millville, but Chatsworth, Mays Landing and Egg Harbor City have one. For example:
