If the groundhog sees his shadow, there will be six more weeks of winter weather. If he does not see his shadow, there will be an early spring. Punxsutawney Phil is the "official" groundhog who gives the proclamation of an early spring or 6 more weeks of wintery weather. This year he predicted 6 more weeks of winter but that's ok since we really haven't had much of a winter to speak of.

Stay warm everyone!
