Tornado was still warned, on the ground, near Joplin, so IMO the warning got out fine. Now if that warning was issued when it was 10 miles west of Joplin, that would possibly be a different story. And people in every single outbreak this year have said they didn't have warning. Even during the Tuscaloosa outbreak, where there was a huge warning time, people still said they didn't have warning. But that's just my opinion, and it doesn't mean much, lol.
