Summer of storms

In one of my previous blogs (about climate change) I wrote that I thought there had been a lot of thunderstorms this summer.

I was right:
“Meteorological Institute KNMI in De Bilt (that place again) counted 25 days with thunderstorms in June, July and August... A normal summer usually has about 14 days with thunderstorms”
