A fairly rare Day 3 MDT risk has been issued for a good chunk of Oklahoma, southeast Kansas, and southwest Missouri, including the city of Joplin. Right now it looks like the biggest threat prompting this is large hail, although the tornado potential is definitely there.
IF there are going to be any significant tornadoes, I would expect them to be near the southern end of the MDT risk - so the Red River Basin, OKC area, possibly Tulsa. SPC hasn't mentioned significant tornadoes so, along with them, my confidence in saying so is very, very low. We'll see what happens.
Hopefully this doesn't bust.
