I'm predicting most will still have decent expectations no matter what they say now out of frustration because that's human nature. As a matter of fact, I bet there will be a fair number who will be optimistic that 2019-20 will have a good chance to make up for 2018-9 because we're "due". If it is another El Nino, these expectations will probably be even higher. Even if La Nina, there will be those who will predict they will do well because they like La Nina better due to 2010-1 and 2017-8 despite longterm climo saying otherwise
By the way, I'm predicting right now that JB will go cold and wintry for most of the E US despite what I think was easily his worst ever E US DJF temp. forecast. He missed much of the SE by a whopping 8+ degrees!!
