Storm just proved again that she can easily hurt him with her lightning within one of the last few issues of Uncanny (IIRC it was Uncanny). Really though she's always been able to beat him with a wave of her hand. There's not really anything he could do if she just decided to lift him off the ground and suspend him in the air while she did her business with lightning and cold. Demon wolverine couldn't do anything when she flew him around not too long ago - he didn't have any leverage. Same thing with Hulk a while back.
