Groundhog Day: The legend of the immortal Punxsutawney PhilEvery Groundhog Day thousands gather in Punxsutawney, PA, to receive the prediction of the beloved Punxsutawney Phil.

PUXSUTAWNEY, Pa. -- Every year on February 2 people keep an eye out for a groundhog's shadow to help predict what the weather will be like for the next few weeks. This year that shadow may be cast on snow.

The legend goes that if groundhog Punxsutawney Phil sees his shadow we will have six more weeks of winter. If he doesn't, spring will arrive early.

Right now the outlook for Groundhog Day in Punxsutawney, Pennsylvania, is for snow. A lot of it. The forecast for Tuesday morning while Phil is making his prediction calls for snow showers and temperatures in the mid 20s. Winds will be whipping up to 25 mph making wind chills feel in the low to mid teens.

Even if it isn't snowing very hard during Phil's televised forecast, there will be at least 4-6 inches of fresh powder on the ground from a weekend winter storm that will make it's way through the Northeast from Sunday through Tuesday.

The celebration, which is over a century old, will look a little different this year. Due to the coronavirus pandemic, there will be no crowd in attendance or guests present, but you can watch the ceremony on the internet via live-streaming.

GROUNDHOG DAY 2020: Punxsutawney Phil predicts early spring

Pennsylvania's most famous groundhog on Sunday declared: "Spring will be early, it's a certainty."

Predictions in the past

Phil is not new to the forecasting game. The ceremony has been going on since 1887.

Scientifically speaking, winter will officially come to an end on the equinox on March 20, regardless of what Phil predicts. But Mother Nature doesn't always follow the timetable.

In fact, Massachusetts, Connecticut, New Jersey, Colorado, Wyoming, Nebraska, and South Dakota actually have their snowiest time of year after Groundhog Day.

For the last two years in a row Phil has not seen his shadow, predicting an early spring.

In the past Phil has been way more likely to see his shadow than not. He has reportedly seen his shadow 104 times, but not seen his shadow only 20 times. Statistically speaking, Phil has been correct in his forecasts about 50% of the time in the last 10 years.

Phil has lots of friends

Phil is not alone in his prognosticating skills. In fact there are many others like him. States like Ohio, North Carolina, New York, Georgia, Tennessee, Wisconsin, Illinois, Maryland, West Virginia, and Michigan all have their own groundhog to use for predictions.

Some of the more colorful names include Pierre C. Shadeaux of Louisiana, General Beauregard Lee of Georgia, and Staten Island Chuck from New York just to name a few.

There's also Unadilla Bill from Nebraska who boasts one of the highest accuracy ratings in the groundhog business.

This means that if you don't like Phil's forecast, chances are one of the other groundhogs will predict something you do like.
