There are many regional specific/situation specific weather data providers. Private weather data service providers have been around FOR DECADES. NWS/NOAA is the most common weather data source provider for the USA but it is most certainly isn't the only one. If you use an app/service that sources data from the NWS (NOAA), that same app/service is sourcing international weather forecasts from other sources. The NWS (NOAA) does not create detailed temperature/weather forecasts worldwide. Go ahead and look at the five day temperature forecast for your ZIP code with all three services.

The Weather Channel (operated by IBM) is one. There are privately operated weather forecasting services as well. The National Weather Service (NOAA) is just one. Multiple weather data providers exist in the USA. I believe all the weather apps fetched data through National Weather Service or whatever it is called.

The basic weather service data is superb, far better than anything I've seen in a US-based weather data source. There are two main shortcomings: 1.) the app's interface is only in Japanese and 2.) the weather data coverage is only for Japan. Returning to the original topic, the best weather app I have ever used is Tenki. If WTEH doesn't update their PGD feed, no one gets it.

The data is provided by the individual companies (terrestrial broadcasters, major networks, etc.). Then for some reason, it changed to become not informative.Īlmost all US television schedule apps use the same data source that has existed for decades, PGD (Program Guide Data) from the Chicago Tribune (at least that's where it came from twenty years ago).
