Definitely should be over six feet tall. This is basically a hydra, it should be massive and hulking. It's a thunderstorm AND a dragon. Not some measly little puff ball. I also think it should weigh more than some of the suggestions here - Grass Knot is really unimportant thanks to Cyclohm's typing, and as mentioned earlier, water is heavy. On top of that, we can't see what's in that cloud, but I'll tell you what's in there: a dragon. That's what.
Maybe 7' if we're counting the heads in its height. As for weight, maybe ~340 lbs? Remember it's got a ton of defense so it's probably not immaterial. There's something in there besides mist and lightning bolts. Plus it gives you something to sit on as you stomp around town blasting civilians with your awe-inspiring thunder dragon.
And yeah, I'll go for the two pre-evos. Most dragons have two. One head, two heads, three heads.
