I use the BOM IR(day and night) satellite for short term cloud prediction.
At my imaging site, the fine resolution seeing seems to be best correlated with the 200hPa jetstream being under about 50kts and the best predictor for this is hidden away in the BOM site - if the jetstream is dark green or worse, the seeing will generally be poor.

The older seeing scales were based on moderate refractors and do not really capture what happens with a larger reflector. The definitions on
http://www.damianpeach.com/seeingscale.htm are probably a lot more use for these telescopes. FWIW, I have never seen seeing corresponding to the "excellent" video.
