CAD can always be underdone. However, I think CAD gets way overplayed on this board. I can guarantee you that CAD and associated cold is NOT always undermodeled. A great example was the "ice storm" we had back in December where temps were supposed to be around 31-32 and so many folks talked about how it would trend colder. Well, it never trended colder and we just did reach 32 and got a little bit of ice in the trees and bushed, but that was about it. If anything, the models overstated the CAD and cold, but most were pretty close. I think the thing is, is that we always remember the times where CAD does underperform and it impacts us significantly to the better. The difference with the storm next week is that there should be colder air available.
