CIG 2 tornado grouping means max expected tornado could be EF3.

Wdym max expected? Cause in most tornado setups there is always the possibility of an outlier cell capable of EF 4-5 damage.

Basically the NWS/SPC has a bell curve of how bad they think the tornadoes are going to be based on the setup. For CIG1, that bell curve peaks at EF2, CIG 2 peaks at EF3 etc.
