I'm in Peoria, IL and was trying to decipher the weather soundings coming from Lincoln, IL today. I read an article earlier today from Tim Marshall "Cap Boom or Bust" and he was saying that a cap value of 1 or 2 is perfect because it will only allow the strongest storms through and they will have all of the free atmosphere to feed on and move through. So I see on the weather sounding that it has a CAP value of 8.1... Does that mean that it is 6 or 7 points higher than what's preferred and that is the main reason why when I look at the satellite view that none of the storms seem to have strong updrafts?

Also, is that why CAPE is only 341?
 
Was the sounding you looked at from 12z? If so, that would explain the high cap level because of the nighttime cooling. From what I see, the cap is pretty much gone.
