This is a Notification Center widget that displays weather information from Weather Underground.
To enable the widget and set your preferences, go to Settings/Notifications/Weather Underground. This package will not install an icon to your SpringBoard.
To use the widget you will need your own API Key from Weather Underground (this ensures that the app can remain free.) Go to Weather Underground to create a free API Key. Select the “Anvil Plan” and the “Developer” option. Enter your API Key on the preferences page at Settings/Notifications/Weather Underground.
