KU ingredients:
MJO in high amplitude phase 8. Check
Blocking in place and decaying. Check
Rising PNA. Check
Dropping EPO. Check
Biggest question mark. PNA. We want it to rise at a quicker pace for a KU. Being in Negative first is great. The rise has to be quick enough.
As it has been said, only 1 out of every 10 systems with the earmarks of a KU actually occured. So 10% chance here to keep everything in perspective.
