Why can't I see the weather information in Notification Center?

After upgrading my iPad 4 to iOS 7, I don't see the weather forecast in the new Notification Center. The calendar is there, and the bottom of the Notification Center has the Yahoo! copyright info for the weather data, but the weather information is not displayed.

Wi-fi is turned on, but I have the location services disabled. When turning on location services, the weather info is shown. What's strange is that on my wife's iPad, the weather info is shown even with location services disabled. Both of our iPads are Wi-fi only, no 3G.

Are you seeing the same behavior? What could be causing this inconsistency?

I realize that this thread is old, but there are so many issues with iOS7, that there are probably many who still haven't found a solution to this. What worked for me: Settings > Privacy > Location Services - Turn on Location Services (if it's not already), and also, scroll down to Weather and make sure that specific app is turned on. After that, the text weather showed up under the date on Notification Center. And I have my Weather app in a folder.

Restart your iOS device.

This seems to be a Heisenberg bug: I restarted the iOS device after removing a "Weather" folder according to this answer here and I got a weather info to the summary "Mostly clear currently. It's 2 degrees; the high will be 9 degrees."

I tested also different settings in Notification Center and the changes requires restart before becoming visible.

It may be that the "Weather" folder is just a red-herring here. Anyway test Restart after changing settings.
