I know nothing about weather, but aren't changes happening gradually instead of overnight? There's no major anomaly that appears all of a sudden. In which case we can assume the every new change will be incorporated in the AI model's training.
As mentioned the bomb cyclone in PNW this year, but also the hurricane that started in the Pacific, whittled down to a trop depression in the gulf (crossing all that land inbetween!) and then spun up into a gnarly hurricane that made a beeline for florida (iirc?). I distinctly remember a lack of worry about that storm system until it started spinning and collecting more stuff a few days after it had left land in central america. None of the models that i know of correctly predicted that it would re-spin, and even the latest updated models with planes flying in the storm still couldn't nail the eyepath - it was essentially off by two whole cities up until it actually made landfall, and then they were a lot more accurate about the land track.
i'd never heard of a storm doing that, but i am not really that in to weather, so it's possible it's in the training data somewhere?
