You can see snow prediction for this particular day while it’s spring there and weather is getting mild, with temperature records usually above 10 - 15°C at noon.

Local and other popular weather forecast services show no such thing. For instance, the french weather forecast agency shows this : http://www.meteofrance.com/previsions-meteo-france/lyon/69000 (click on ‘jeudi 27’).

@the-n3i Das ist echt interessant. Ich werde mir das mal genauer ansehen. Vielen Dank für den Hinweis. Ich wusste gar nicht, dass die DWD Daten frei zu Verfügung gestellt werden.

(I better switch back to English because of other users who could read this issue later). Thank you very much for the link. I’ll check the format of the data, and how often they are actualized and other things like that.

so how about accessing different countries’ official weather services? At least the German weather service offers free FTP access and I’m sure others do that as well. Using a local weather service should give more accurate predictions, right?
