Punxsutawney Phil sees his shadow, predicting 6 more weeks of wintry weather

The video discusses the tradition of Groundhog Day, where Phil the groundhog predicts the weather based on whether he sees his shadow. If Phil sees his shadow, it means six more weeks of winter; if not, spring arrives sooner. This tradition has been practiced for over a century in western Pennsylvania. However, Phil's accuracy is less than 50%, with 107 shadow sightings and 21 no-shadow occurrences recorded.
