Tuesday is Groundhog Day. Tuesday is Groundhog Day. Tuesday is Groundhog Day.

All jokes aside, all eyes will be on Punxsutawney Phil when he wakes up Tuesday morning and checks to see whether a shadow follows. If so, as legend has it, the United States is in for six more weeks of cold weather. If not, spring is coming — soon.

Thousands of people will turn out Tuesday to see Punxsutawney Phil, a 20-pound groundhog who lives in Pennsylvania, but you don't have to brave the crowds. Tune in here for a live stream of the event, which starts at 6 a.m. EST.

Last year, Phil predicted an extended winter, and his forecasts are right "100 percent of the time, of course," according to his website. But the prognostication doesn't totally hang on the shadow test. Every year, when the groundhog emerges from his burrow on Gobbler's Knob, he talks to the president of the Groundhog Club. They converse briefly in Groundhogese, and then the human reveals the news to the world. The 2015 announcement came at about 7:30 a.m. EST.

This year marks the 130th anniversary of Punxsutawney Phil's Groundhog Day celebration. If you're not a fan of his weather forecast, however, you have options. Check in with Staten Island Chuck in New York here or General Beau Lee in Georgia here.

If you're hoping for a more scientific prediction, consult with the National Oceanic and Atmospheric Administration. "While Groundhog Day is a way to have a little fun at mid-winter, climate records and statistics tell us that winter probably isn't over," it wrote on its website. "Climatologically speaking, the three coldest months of the year are December, January, and February, so winter typically still has a bit to go when the groundhog comes out in search of his shadow on February 2."
