Much of the remainder of the metropolitan area lies in the transition zone from a temperate/humid subtropical (Cfa) to a humid continental climate (Dfa), and it is only the inland, more exurban areas far to the north and west such as Sussex County, New Jersey, that have a January daily average of -3.0 °C or below and are fully humid continental; the Dfb (warm summer subtype) regime is only found inland at a higher elevation, and receives greater snowfall than the Dfa region.
