Voter registration deadlines

I’ve recently become eligible to vote. The problem is Pennsylvania requires a person to register 30 days before the election if he wants to vote in it, and as usual I didn’t know about this. (Please, no flames.) So the question: is it possible to legally get around this deadline and vote November 5? It seems like an important election for the state, and of course, me being the model citizen, I want to do my part. So…any suggestions?
