PUNXSUTAWNEY, Pa. (AP) - It may be hard to believe as a large swath of the U.S. thaws out from a bitter polar vortex, but spring is coming early, according to handlers for some of the country's most famous prognosticating groundhogs.

Just before 7:30 a.m. Saturday, Punxsutawney Phil emerged from his burrow in Pennsylvania at sunrise and didn't see his shadow. Nearly the same series of events unfolded about 300 miles to the east, where Staten Island Chuck's handlers also revealed the same prediction.

The festivities have their origin in a German legend that says if a furry rodent casts a shadow on Feb. 2, winter continues. If not, spring comes early.

In reality, Phil's prediction is decided ahead of time by the group on Gobbler's Knob, a tiny hill just outside Punxsutawney. That's about 65 miles northeast of Pittsburgh.

New York Mayor Bill de Blasio stopped attending Staten Island's Groundhog Day ceremony in 2015, a year after he accidentally dropped the furry critter that died a week later.

And he wasn't the only New York City mayor who struggled with the holiday. Former Mayor Michael Bloomberg was bitten at a Groundhog Day ceremony in 2009.
