Colossians 2:17 Which are a shadow of things to come; but the body is of Christ. [kjv]
α εστιν σκια των μελλοντων το δε σωμα του χριστου [gnt]
The Punxsutawney Phil tradition dates from about 1870.
The Pennsylvania Dutch superstition may come from the German
"Dachstag" ≈ "Badger Day" with a similar tradition. The German word
"Dachs" ≈ "groundhog" and is the source of the English word
"dachshund".
What does the French groundhog see on February 2?
His chateau. This is a holistic burrow.
Pennsylvania Dutch superstition: If a groundhog emerges from its burrow on February 2 and sees its shadow, there will be six more weeks of winter. Otherwise, spring is near.
