DETROIT - It's not an official holiday, but many all across the country are waiting to see if Punxsutawney Phil or Howell's Woody will see their shadows.
The yearly tradition is to determine whether the country will see six more weeks of winter or and early spring.
So, how did Groundhog Day get started? In 1887, German immigrants brought the tradition to Pennsylvania after The Romans declared six more weeks of bad weather, or the "Second Winter" if a hedgehog casted a shadow on Candlemas Day.
Tuesday will make it America's 129th weather prediction.
At the Howell Nature Center, the fun begins at 7 a.m. with breakfast. The celebration gets underway at 7:45 a.m.
Pennsylvania's most famous groundhog Punxsutawney Phil and the top hat-wearing members of his inner circle plan to reveal their forecast at sunrise, just before 7:30 a.m.
