The one caveat, which is hard to evaluate, is whether the high pressure (and associated upper level configuration) will be so anomalous, that the AI will, by its nature, not predict it. The AI models are trained on some amount of reanalysis, and so they can't/won't predict extreme or record-breaking events well. Will this setup be record-breaking? Hard to say. But that's something to keep in mind when evaluating the AI models vs the physics-based models.
