Which, at least for the Oslo area, offers more reliable predictions than Apple's weather app (which is always weather.com, afaik) Having said that, and having the Norwegian Meteorological Institute down the road from where I live, their local predictions are often completely off on rain, to the point I always bring a raincoat when going out.

I prefer the weather radar for that. Actual clouds and the live direction they're going in is a great predictor of rain. In fact I'd love to improve lightning detection by making a script that also takes into account wind direction, since lightning tends to travel with clouds. It could be as easy as using an ellipsis directed as a kind of weather vane, perhaps stretching out with wind speed. Currently I use a simple circular distance calculation to detect proximity.

For local rainfall predictions, the best solution is to look at the weather radar service they have.
