Thanks for clarifying. And I agree with everything you've written. I'm (clearly!) not an expert. Would be fun to see this done as a challenge similar to the old Netflix recommendations ML challenges.
Like, for my purposes, I'd simply like to know the temperature trend for the next 3-5 days. Will each day's high be hotter or cooler than the previous?
Bonus points: what's the high temperature for the next 3 days (within say, 3°F).
Anecdotally, using these standards, this seems to be consistently wrong where I live for much of the summer. I don't pay attention in the other seasons as the weather is much milder.
