It's a difficult forecast. Not many solid analogs. I would imagine AI models would struggle especially because of this since they compute based on training data.
Yesterday the AIFS had 850mb temps approaching 30C west of the cascades. Seems a bit chaotic across all operational guidance right now. Pacific typhoon noise, east pacific hurricane activity or the building Psycho Hulk El NiƱo perhaps? Models do seem a little more spastic than usual right now.
