Thunder's vulnerability to Ice makes some sense, depending on the situation. Ice can take a real toll on electric cables, like the kind found on utility poles (it's one of the main reasons ice storms are dangerous), and air becomes less conductive when cold (conversely, metal becomes MORE conductive when cold). Though Ice being strong against Earth makes more sense overall (ice can freeze the ground).
