I'm in the north of England on the edge of the Pennines. I've been using DarkSky because it does localised hour by hour predictions, which have been pretty good . But recently it's been really off - the temperature is accurate but the precipitation probability has been very poor. If you're going on a longish run, it can be really annoying if you expect it to clear up and actually it gets worse. I'm not bothered about the weather as such, I just want to be able to be prepared.
Accepting that no app is foolproof has anyone got any recommendations?
