Its possible that lightning bending has become more widespread since the end of the last series. Before it seemed pretty heavily implied that it was a firebending technique that was pretty much just passed down through the royal family (the only firebenders who ever used it in the show were all fire nation royals; Iroh, Ozai, and Azula). However, Zuko might have opted to have the technique (and redirection) taught more widely so as to perhaps prevent such a technique from being monopolized by the royal family.

If that's the case, it becoming more widespread would also make it easier for people to improve upon the technique (more people working on it makes progress quicker and more likely). Thus, maybe a skilled enough firebender could generate lightning similar to Ozai.

Just food for thought.
