that's a fair point. I still dont recall jean ever manipulating weather excluding the examples of lightning, which lightning is a direct result of weather but it isnt weather.
why do you come to this conclusion?
did you happen to see the scans of what qualifies one as an omega? also ororo has exceeded the natural limitations when exhibiting weather displays a few times. she doesnt typically alter the weather beyond as it naturally exists to not adversely impact it to a point where it would be irreparable but again she has done it. also, thors power mostly hinge around mjolnir but remove this and he doesnt have much of any inlrssice displays of weather manipulation on his on.
