If there were a briefing like that for central Oklahoma, how would I get to it?
I tried substituting oun for tsa and found a home page, but no apparent link to an A/V briefing.

I added "briefing/player.html"
to the url and got a briefing from the NWS Norman Forecast Office about a Tornado Watch issued back in November.
