Well, only if you went with a generic, boiler-plate-ENSO forecast....really immaterial AFAIC because I did not....that said, the RONI and MEI are still down there, so that would give me pause before summarily declaring it dead. That said, the sensible weather moving forward probably won't hurt your argument if you want to claim that...but I would argue the inverse of what you say when we have ENSO congruent sensible weather by chance, despite your argument that it really isn't coupled or the "driving force" per se.
Assuming it is dead, people like to conveniently dismiss the notion of a lag, too....it doesn't just "shut off"...but this event was fairly weak, anyway....which is part of the reason I didn't go very warm in February.
