@stormtracker I’m looking at the ensemble members in the eps and gefs that had hits from that wave on the 25th. They phase that NS wave that the op run just ran out ahead. That has to be behind the southern feature and phase. Otherwise the southern feature won’t survive the shred factory flow. If that doesn’t happen we need to wait as the trough/ridge retrograde until it pulls back enough to let the eastern trough axis pull back some.
