Other variables can be significantly in error due to the siting of the station: under a tree, not aspirated, in the wake of a building, on a rooftop, etc.
I would think there is still value there, at a sufficient scale.
Navigation inside the app doesn't feel intuitive at all. Maybe it's more similar to default experience on android? No idea. Map/Hourly/Daily buttons don't work as tabs. Daily view arrives with scrolling up animation, but when you scroll to close it there is a large ad banner (well, understandable, but awkward) and for some reason weather news (why would anyone want it there or at all?). I've noticed "close" button later, but it was in bottom right corner for some reason.
Plastering "RealFeel(r)" everywhere was horrible idea. It is corny, unnecessary and reads worse than "feels like".
Then I got my answer: they focused on the temperature forecast, while since I bike to work what I was interested in was "is it gonna rain today?"
I get that it's difficult to predict when and where rain might occur, but I'd much prefer a rough probability scale to nothing. On the bright side, they have a real-time, radar-based 90 minute rain forecast now, so at least if I check it in the afternoon I can jump on my bike and get home before I get wet.

Rain is not easy predict, especially long in advance. Just taking things with a grain of salt here. If you truly believe that forecasting actual rain is not very hard, please start a new weather forecasting company and give it all you got! However i'll tell you, it's not that easy. Just because a computer model 'runs' does not mean it correctly modeled the atmosphere. All models are imperfect bud and those imperfections get amplified by 10x when trying to simulate earth+atmosphere systems
As an example, they may forecast that 30% of the areas your city will report rain tomorrow. They may have an high level of confidence in this prediction (and verify it to be correct after the fact). It may still not be very useful to you, since the one outcome is so different to the other.
That said, I agree with your that the predictions should be presented in a more scientific manner. In fact, one irritating pattern is that rain probability and the predicted amount of rain sometimes get combined into a single percentage, which no longer represents neither the probability, nor the amount. It's some kind of weird combination of the two.
Just last Thursday they reported zero precipitation for the entire day, not a hint of rain. Yet we got 3 hours of medium-heavy showers in the afternoon... not a very uncommon combination. If I had known there was a 30% chance of showers, I would have packed my rain jacket.
