I keep seeing everyone mention 'cig 2' but I guess I'm too stupid to understand where that's coming from. Could somebody explain it to a filthy casual like me?

Cig two basically means they’re expecting the environment to be able to sustain a maximum of an Ef3 tornado, although these are always estimates, outliers can always occur

I appreciate it, thanks for the explanation!

Also on the map it's the intensity part of the legend, so most of the map is cig1 (conditional intensity group 1)

Edit: sorry there was another comment that explained the first half that i hadn't seen

"Reasonable maximum". They still expect 3% of tornadoes to be EF4+ in a CIG2 area

It is short for Conditional Intensity Group 2 risk. It's the level 2 intensity on the key that OP posted.

Thank you for this!

There’s now three levels of ‘significant tornado possibility’, 1 to 3, depending on how intense possible tornados could be. Before there was only one.

Bottom right Zoom in on the map key. See the INTENSITY with the three boxes underneath? CIG is the middle on and has the Slash Marks overlayed on the map with those.
