Just reloads and reloads of -PNA as we possibly approach 90 degrees after April 15th.
El Nino's don't have this kind of -PNA in April usually.. also remember the last El Nino (Weak) in 2018-19 had a +200dm -PNA in February, which is usually ENSO's highest correlated month to the N. Hemispheric pattern.
-PNA through 15 day models usually correlates with cooling in the subsurface ENSO, which given the time pass gives us much lower chance for Stronger event. And Weaker El Nino's are not breaking the, what some would call, -PDO.
