Contradicting Rodents

So, Puxatawney Phil saw his shadow today, indicating 6 more weeks of Winter. However, Staten Island Steve (Or something like that) did not, indicating an early spring. So, which one is right? Neither. Groundhogs aren't the ones making the predictions. And groundhogs can't technically "see" thir shadows. I'm looking at the Wikipedia page, and I sense a pattern. Take a look.
