Punxsutawney Phil delivers his Groundhog Day forecast on how long winter would last every year. Here's a closer look at the rodent we rely on to predict the weather. Phil comes out around what time each day in February and begins the tradition of predicting whether or not there will be more snow this year in Punxsy, Pennsylvania. He does this by looking out for some burrowing animals he calls groundhogs. When one is seen, that means it's early spring and there's a good chance of more snow. If no groundhog is seen, that means it's late spring or early summer and there's a good chance of less snow. Phil has been watching groundhogs for most of his life and uses their behavior to make his prediction. If the groundhog moves its head from side to side when placed in front of a light source such as sunlight, that means there's an equal chance that there'll be more snow or less snow this year. If the groundhog hides under a bush or in a hole when approached, that means there's a good chance of more snow. If you watch Phil on Groundhog Day, he'll sometimes get a prize if he gets it right.
