Integrating Radar images into Map or Custom widget

Integrating Radar images into Map or Custom widget

Has anyone successfully integrated a radar image as an overlay in a map widget or custom widget? I am able to integrate static weather data using the Accuweather APIs but what I'm really after is the current radar. Accuweather and the National Weather Service offer these images through API but it's unclear how to integrate into a Tago widget. Any examples would be greatly appreciated.
