Among all the destruction Apple has wrought when they killed DarkSky, they also failed to bring back the weather history feature. You could go back decades and see the weather anytime, anywhere. I miss it so.
If you are interested in German weather, I can recommend the DWD WarnWetter App. It is so good that the competitors sued when it was free. Now it costs a one-time fee of about 3€.
I've learned that I just want to look at the radar. There's a big difference between "it's going to drizzle all day" and "spotty storms within 25 miles of you"
I have learned to ignore its predictions. It will say that it's sunny outside, and I'll look out the window, and we're having a hailstorm.
