We have crazy amounts of hoar frost up here this week. I’ve never seen it like this as we’re usually pretty dry in the winter. It sure makes for pretty pictures.
The frost line is migrating north, in central New England we have a mild frost, maybe 18 inches deep, not 4 feet, @ mid January, where we over the last few decades were in a deep freeze. This is supportted by the axis north pole migrating from Canadian Arctic towards Saberian Arctic, as science has proved and said for years & years.
