Yup... been following. Next ridge roll-out/flex may occur starting ~ the 28th of June +.
May be a hot summer in the works here. Although every year seems to be some positive anomaly comparing to climate anyway lately. But I mean even relative to that.
( as a side thought ... it almost seems to me that we should also be comparing the model depictions, and verification (both) against the average departures. In other words, against d(climate) - possible the average SD during d(climate) being most important. Because it seems to get lost when everything is +.3 to +3 to +33 and every possible decimal in between. )
Anyway, there's a coherent R-wave signal for a wholesale hemispheric nadir around 120 W that is ending up as the residual/rest state in all ensemble systems, after these mid range attempts to change ultimately fail. This began to formulate, about 2 weeks ago, when we began posting/warning this heat wave was out there. So long as that footprint stays the same, I would be inclined to suspect all fronts and troughs kicked E across the continent have a higher chance of downward amplitude.
