Also I don't get what happened but I think it was AccuWeather or weather underground in the early 2000s where it was to the minute accurate and it seems like it's gotten worse since everywhere.
We do have such models. A bunch of them actually:
- Google DeepMind's "WeatherNext2" - Microsoft's Aurora - NVIDIA's FourCastNet-3 + Atlas + Climate-in-a-Bottle - ECMWF's AIFS ...
The list goes on. Plenty of small startups have repeated the recipe for building these types of models with their own architectural twist, too.
The rainbow and sunset alerts are really cool ideas. I'm now realising that a simple tie-in to astronomical phenomena could prompt a useful notificationa around it e.g. being worth going stargazing that night. I ski–learning that the near-term forecasts just changed would help me change my schedule the day before versus trying and failing the morning of.
