I understand that weather on TV can’t be hyperlocally accurate. But a weather app on my phone has my exact GPS coordinates. Why can’t it tell me exactly when a rain cloud will be passing over my location?
It’s gotten to the point where I just use precipitation maps to figure out my rain chances for the day.
The hourly forecast is mostly useless because it’s not a chance % but a % of the area that will be raining.
Does most weather data in the US ultimately come from weather.gov? No idea about API but maybe it can be scraped from the web.
NWS is a great resource, but there are a startling number of other organizations that collect weather data.
