The final answer is that Storm would win, in all Thor's defense and all his powers, he is a fellow manipulator with a God status that is all. His powers may have a deadly punch, but she controls the exact same thing as she does therefore it then becomes a matter of usage and skill. Storm as stated has spent her entire life in the air, being weather from the time of her birth the weather has had a connection to her and she to it. Not by a voluntary use of power, or calling on its use, it reacts to her like she reacts to it. Her control isnt given by some power, or some magic but she is the force at which she controls the weather making her it in every aspect, She doesnt summon a gust of with she feels the need for the wind, She doesnt ask may i use u, it comes to her for her aid, to stablize her out, it is a power nature shares fully with storm as storm is a whole being, thor just uses a force to create a control. Stories/Comics/Videos all show storm not only sensing things in her own area but things around the world, and from other worlds. Sorry guys, ur big god of thunder may use by force, but natures cry for storm is a power unlike anything we could imagine.
