I noticed my local weather forecasts from Google search have gotten significantly less accurate these days.
Like, they consistenly called for freezing seasonal overnight lows many weeks before it was remotely probable. You'd get better predictions asking anyone who's lived here a couple years. In fairness, I'm in a region that's notoriously difficult to forecast, but the popular non-Google sources seem to be generating better predictions.
I wonder if the rollout of this new model is related (either occurred and made it worse, or will come and make it better).
I'd love to get some hard data. Are there any sites out there where you can compare past performance of different prediction models at a very localized scale?
Not affiliated, just thought it was a neat idea when I stumbled upon it during some hobby weather research last year:
ForecastAdvisor will show you the accuracy of the major weather forecasters, including AerisWeather, Foreca, Microsoft, the National Weather Service, OpenWeather, The Weather Channel, Wetter.com, WeatherBit, World Weather Online, and others. They also provide links to your city's weather forecast from all the other weather forecasters, so you can compare for yourself.

Open-meteo has a free non commercial api. Their api exploration page is super powerful and can pull and graph model-specific forecast data. It doesn't have weathernext but it does seem to have many of the big models if you want to geek out. Does take some figuring out though.

comparing model performance for a location seems such an obvious thing but it's basically non existent, I wonder why
