The southern stream and primary northern stream have already consolidated into a closed, negatively tilted mid-level low offshore. The Alberta clipper energy upstream is elongated and lagging, feeding into the broader trough rather than diving into the base at peak intensification as a third discrete impulse.
In other words, the phase has already happened and the system is maturing, not undergoing a fresh three-way interaction.
If that upstream energy were carving sharply southeast and visibly tightening the core at this frame, we’d be having a different conversation. But here, the structure is consolidated and occluding.
This is a powerful double phase with backside reinforcement, not a clean triple crash.
If we could get that Alberta clipper to come in... we might get Moses to start building an ark with skies!
