Punxsutawney Phil -- perhaps the world's most famous groundhog -- saw his shadow meaning, according to legend, that we will have six more weeks of winter.

PUNXSUTAWNEY, Pa. -- Here's a look at Groundhog Day, an American tradition that is meant to predict when spring will arrive. The groundhog emerges from its burrow on February 2. If the groundhog sees its shadow when it emerges, there will be six more weeks of winter. If it does not see its shadow, spring will arrive soon.

It was a big party in Punxsutawney this weekend. "This is my favorite holiday," one local says of the fuss-free day, adding, "You don't have to even see your in-laws." This year, Phil saw his shadow.

In an annual tradition, Punxsutawney Phil saw his shadow during the annual Groundhog Day on Feb. 2 in central Pennsylvania. That means six more weeks of winter.

Punxsutawney Phil has forecast six more weeks of winter in North America after seeing his shadow on Groundhog Day.
