Frost and freeze warnings are in effect for the interior northeast tonight. The freeze warnings are mainly confined to the higher elevations in the Appalachians where temperatures could dip into the mid-20s Fahrenheit. The frost warnings cover the lower lying areas where temps may hit the freezing mark tonight. A quick look around the internet suggests this isn’t an abnormally early frost, although it may be slightly earlier than average for some spots.
This comes in the wake of a cold frontal passage earlier in the week that brought frost to parts of Minnesota. It appears another shot of cold air will be ushered in this weekend across the northern Plains and upper Midwest that may spread frost across a larger area than this most recent front. Again, all of this seems pretty normal, but it’s another sign that Summer is winding down and the transitional season of Fall (or Autumn) is upon us.
