Comment on GenCast predicts weather and the risks of extreme conditions with state-of-the-art accuracy

One thing that always bothers me about weather forecasts is they are not very specific, 24 or even 12 hours into the future. Like, they are correct that it will rain, but then somehow that rain always just misses me, and goes a few miles to the south, or something. Or it stops just a few miles shy of me.
If this can give more specific forecasts in the immediate future, that’ll be nice to see.

As much data as meteorologists have, it seems like they need more data. For example, I can look at the temperature in my weather apps and see two totally different measurements than what I see from the thermometer outside my house. Just simply due to the fact that the weather stations that are used for the apps are not at my house and so the conditions are different there. If there were more stations, for example, they could report and then take an average of all the reports that came in to get a more accurate measure.

Yeah, they could certainly use more resolution in their data, I’m sure they wish for it all the time.
But to pick on your example, they have certain requirements for specifically how they take the temperature which explains at least some of the discrepancy between them and your thermometer. For example, the thermometer must be in shade, must be iirc 2 metres off the ground, things like that.
