Dr Jack's BLIPMAPS

I came across Dr Jack's BLIPMAP forecast page
http://www.drjack.net/BLIPMAP/NE/index.html

Probably a lot of good information if you know how to use it (and some very
pretty maps), but also not exactly intuitive and slightly overwhelming.

Anybody find good use of this material, and in an orderly process how do you
proceed to a practical forecast of what may happen thermal wise today at
your gliderport?
