I've seen it mentioned, and while it's prudent not to proselytize doom based on speculation, let us remember that a study that initialized a GEFS synthetic event set for outbreaks estimated that so called "1-in-1000 year" outbreaks may feature 400 tornadoes in a day !
Reminder we have almost no observed historical timeframes for large tornado outbreaks. We have less than a hundred years of good data. This is almost nothing in terms of a historical record, and even less geologically. For all we know…
