Why is Weather App (iPhone/iPad) not reporting current Weather channel data?

Our phones, iPads, and watches are always reported wildly inaccurate temperatures and forecasts. The data displayed does not match that on the Weather Channel site, even though Apple states that as the source of the weather data.

For example, today, it never got above zero anywhere in my zip code, much less location. All Apple weather apps reported temperatures in the teens, +17 most of the day, which is totally bogus. The forecast is also ridiculously wrong.

If it were one device, I would imagine I need a restart or something. But we have 6 different devices, all reporting totally wrong weather data.

Anyone know what's up with this?

PS. All devices running most current OS releases - IOS, iPadOS, WatchOS. All have been restarted. This is an Apple server / platform issue, not a device issue.
