Ahh, it's exaggerating the block. AI has nothing like that...it shows a different problem, a consolidated bullseye vortex over James Bay.
Speaking of AI, I have been watching it closely. It seems to work rather like an ensemble...very good beyond four days, not as good as the operationals within four days. I would surmise that it is better in the longer range because it does not make compounded errors like the operationals. Within four days, the operationals are better as they are making a detailed analysis of the current atmosphere rather than just recognizing patterns.
