Right off, I can think of 2 ways, the second one you already know:
1) If you could fetch and save the data as a text file, then you could assign it to a macro in BI and display as an overlay on either a stored image or on a regular camera video.
2) Or if you can obtain a URL to an image that is updated periodically as is the radar animated GIF then that could be displayed by BI (as you know).
