Solar flares and freaky weather (Oaklahoma Tornado?)

It just struck me that maybe the recent solar flare activity might be partially responsible for the freak weather conditions, and tornados in particular.

What are the connections, if any, between solar flares and weather on earth. Is there any evidence to suggest that in the future, rather than putting all the efforts into worrying about radio and communications interfearence on earth after a large solar flare, having the foresight to warm or prepare for freak weather, tornados and wind storms in particular?

Maybe it was Solar Flare M3.2 of May 17th 2013?
