Minecraft thunderstorm

So the context for this question is that I’m making a fantasy (hopefully) survival world, and to add to the ambiance (and fun) I want the world to be constantly night, as well as being eternally in a lightning storm.

These were both pretty simple tasks, but when I put them both on, I was struck (pun absolutely intended) by the relative lack of thunderbolts that were appearing. Is there any way to increase the chance from 1⁄100,000 to, say, 1⁄100,0?
