> I can't even begin to count how many times I've had this conversation with Siri. I live in Toronto, Canada, which stretches about 40km east-west, and 20km north-south: If the west-end (Sherway) gets hit with rain, but the east-end is dry, did it rain "in" Toronto when folks in Scarborough didn't experience it? Was the forecast wrong? If it snows in North York but is dry at Billy Bishop, was the precipitation forecast "wrong" for one particular group of people?

Apple Weather uses your precise location if you allow it to, meaning it knows your location down to a meter, network and positioning issues etc notwithstanding. It doesn't have to guess your weather based on "Toronto", it knows your GPS coordinates. There is no technical limitation here, as I outlined in a separate comment thread [0], other apps already give you weather data and predictions with this granularity.

    Fur Deutschland... On a serious note I'm dealing with this as well - I live in a middle-sized city in the centre of the country, not in Kraków!

Toronto specifically has (a) all sort of heat island effects, (b) certain areas are effected by the lake and how weather systems cross it at certain angles, and (c) has enough of an elevation change going north of the lake (e.g., Niagara Escarpment) that there are a few ˚C change in temperature that makes the differences between snow and rain.

This exists on a smaller scale too. I'm in a town perfectly covered by a small hill range from the direction the wind is coming 99% of the time. This means almost every forecast for rain is valid 3km south and north of me, but not in the town itself.
