What source does Apple use for their Weather app?

I thought it was the Weather Channel but Apple’s app doesn’t match their app. Are they using something different now?

There's a Weather Data link at the bottom of the app.

On macOS, the same link is within About Weather, on the main Weather menu (upper left of screen).

Where I live, Apple Weather rarely matches the source(s)...

Right it takes me to a website that says Weather Channel. But it doesn’t match their app so…

No, that's not what it says. This is the page it takes you to: https://support.apple.com/en-us/105038

It states:

10-day forecast
A 10-day weather forecast is available for most countries and regions. Unless otherwise specified, the 10-day forecast data is provided by Apple Weather.

Next-hour precipitation
Next-hour precipitation forecasts and precipitation notifications are available for Australia, Ireland, Japan, the United Kingdom, and the United States. The information is provided by Apple using data from national weather services.

Air quality
Air quality information is provided by BreezoMeter for Austria, Belgium, Canada, Czechia, Denmark, France, Germany, India, Ireland, Italy, Japan, Mexico, Netherlands, Singapore, South Korea, Spain, Switzerland, the United Kingdom, and the United States. Air quality information for China mainland is provided by QWeather and reflects data from air monitoring stations. If you use iOS 14.1 or earlier, you’ll see Air Quality information provided by The Weather Channel.

Maps
Temperature maps, wind maps, and 12-hour precipitation maps are available for most countries and regions. Next-hour precipitation maps are available for Australia, Ireland, Japan, the United Kingdom, and the United States.

Temperature and precipitation map data is provided by Apple Weather. If you use iOS 15.2 or earlier, you might see some temperature and precipitation data that's provided by The Weather Channel.

Unless otherwise specified, temperature, precipitation, and wind map data is provided by Apple Weather. Data for air quality maps is provided by BreezoMeter and QWeather.

In iOS 15.2 and earlier, a lot of the data came from The Weather Channel, and the app showed The Weather Channel's logo at the bottom. In iOS 15.3 and later, Apple updated the app to use their in-house solution (Apple Weather), which is most likely from their Dark Sky acquisition. Long story short, I think Apple is trying to re-invent the weather forecast by aggregating data from various sources and coming up with their own. It's no longer just directly from The Weather Channel anymore.
