First summer storm?

It happened this afternoon: a huge, powerful, violent storm, with hail and thunder. The sky was dark, so much that it look like night was about to fall. We had storms earlier this year, in fact very early in the year, but this is the first one that looks and feels like a summer storm. We are at the end of May, it is still springtime, but it feels already, at last I should say, that summertime is coming. I often think that summer is baptized by a thunder storm. I wonder if that was it today.
