Punxsutawney Phil predicted an early spring on Groundhog Day after he failed to see his shadow. The groundhog's prediction Saturday morning in Pennsylvania comes as the Midwest reels from record-breaking low temperatures due to the polar vortex. Groundhog Day originates in German lore. According to legend, if a fuzzy rodent doesn't see its shadow on Feb. 2, spring comes early. If the animal does see its shadow, winter goes on. The tradition brings thousands to the town of Punxsutawney, 80 miles from Pittsburgh. Groundhog Day is also celebrated on Staten Island, where the similarly furry Chuck also predicted an early spring.
