I think it depends on other variables. An epo alone still won’t do it. Especially if the epo is linked to a wpo ridge with a full latitude central pac ridge. That leads to too much SER. The key to 2014 and 2015 were other variables going our way. In both the pacific had a trough under the ridge. We have that now although super long range guidance wants to establish a canonical Nina look but I don’t buy it until it gets inside 15 days. It’s been stuck at day 17-20 all year.
2014 there was a ridge from the epo over the pole that depressed the trough in the east. 2015 a TPV lobe got stuck in Quebec doing the same. Those were critical factors in making those years work. We seem to have some of those same factors on long range guidance. My interest in the pattern goes beyond the epo but there are other more critical similarities to 2014-2015 as well. Those matter more imo than the epo.
