The notion of a "dusting" of snow is not a definable term, but in my way of thinking we already have two inches of snow with no stopping for the next four hours. A little beyond a dusting.
Of course, the ground is not frozen yet, so there will be no affect to traffic or roadways. Everything else is covered with the first snow of the year.
Dropped a couple of degrees in temperature, but it's about right for snow.
