I feel like this is a pop quiz
Yeah, it's normal, though it does seem to be a bit to the extreme recently. Typically the lull would be starting now and "ending" in about five or six weeks, slowly building into September for the fall season.
As for major outbreaks in July or August, I'm sure the WP pages would help you with that

Models have been playing up on this too, I've seen the GFS hint towards a couple of noteable derechos in the OH/PA/NY-ish region after the past couple heat waves, though neither actually occured. Decent line of severe happened at the end of June, and just some popcorn and pulse convection earlier this week.
Needless to say, it's quite boring for now . . .
