Lightning

Although we may experience a few showers, it is quite warm outside. The thunder risk looks low with most storms over Denmark. 

I think there is some link between thunder activity and Es, although I have not studied it. I think it has something to do with sprites? There must be people who know far more than yours truly! If you know the link, please leave a comment.
