Earlier quoted context omitted.

When you say Windy can get it wrong, isn't it really the underlying forecast models that are wrong? It's unclear to me if Windy is doing much more than creating a great presentation of existing data. Their website does list an open ML role, though.. I wonder how much rolling your own weather forecast is tantamount to rolling your own crypto??

By default, Windy uses the ECMWF weather model. You can also change it to GFS or ICON, which many american forecast websites use. ECMWF, GFS and ICON are made by national/international forecasting agencies. IBM also has its own proprietary weather forecasting service, notably used by The Weather Channel. Other apps mostly use one of these models or aggregate predictions from different services (e.g. AccuWeather claim…

Is it not the case that IBM bought the weather channel to acquire the technology with no interest in the WC business?

over the past few years my use of weather apps + forecasting has really been improved by reading alongside them the local NWS office's "area forecast discussion"which is published multiple times a day by the station's meteorologists: https://www.wrh.noaa.gov/total_forecast/getprod.php?new&wfo=... It's really great to be able to contextualize the state of a Windy map, for example especially in Seattle where the weathe…

Windy has multiple models which is great to check how reliable the forecast is - if they diverge then its a clue. In general, the forecasts are great where there is a lot of good input data, like in western Europe and around the Alps. In eastern europe and on the ocean the forecasts can be way off. This is a risk because the pretty graphics and high time resolution somehow associate with precise forecasts.

I wish weather forecasters would be more upfront about the accuracy of their forecast.

For example "Our rain/no rain 2 day in advance forecast for Seattle was accurate 280 days last year".

If all providers published that, I would be able to get my weather from the best forecaster for my area rather than guessing.

Bonus points if there is a more scientifically rigorous metric to compare by that they all publish.
