Many books or other cartoons have a character that possesses Lightning but also Wind (i.e. The Heroes of Olympus series—Jason).

Yes, I'm sure that's completely reasonable. Still, my only thought was that Wind and Lightning don't connect much, so Weather combines them into one element. Plus the reasons I gave above.
