A few years ago I heard it said that a 5 day forecast has the accuracy of a 48 hour forecast from two decades ago.

- heavenlyblue 5y agoIt does seem to me like a lot of that accuracy comes from real-time metric collection from all of the stations around the world (And there are many more stations, too). For example, in London iPhone gives you almost real-time "current weather" state. Stuff like "it's raining now and it's going to stop raining in the next 5 minutes". You can only do that via collecting the radar data in real-time and correlating it with GPS. Not so much prediction.
