Valentine Groundhog Day Climatology

February 2 is celebrated as Groundhog Day. One of the most famous groundhogs is Punxsutawney Phil, located in Punxsutawney, PA. It is said that if the groundhog sees his shadow, he predicts 6 more weeks of winter, otherwise the prediction is for an early spring. While the prediction of the groundhog is not always right, many enjoy the tradition. Below is a climatology for Valentine on Groundhog Day, February 2.
