Groundhog Day means Punxsutawney Phil makes his grand appearance to see whether spring is right around the corner, or six more harsh weeks of winter are ahead. The rodent has predicted the weather for the past 135 years, but his yearly prediction is only accurate about 38% of the time, meaning you are better off flipping a coin. His shadow has been seen about 80% of those years, meaning the groundhog will return to its burrow with six more weeks of winter.
