The MRF (and other medium-range forecasting models as well) repeatedly placed their emphasis on the second upper- level wave (approaching the east coast on Wednesday the 26th) spawning significant east coast cyclogenesis. Each run above predicts a significant east coast trough for Wednesday. Instead, since the wave the day before amplified so greatly, this wave ended up passing quickly and harmlessly out to sea.
