I thought Yoda was just guiding the lightning not creating it.
sure looked like he created it to me.
Big difference between manipulating the weather to create lighting and firing it out of your fingertips. It’s been suggested in the past Yoda used the Force to make sure Luke crashed in just the right spot on Dagobah. That was some choppy weather he hit coming into the atmosphere.
I don’t think he just manipulated the weather.
