Is there any way to find out about Twitch drops in advance?

I've been keeping an eye on the Twitch page that shows all current drop campaigns, because I missed the one on the 21st. Then I missed the one on the 27th too, so I started checking multiple times today (the 28th). I checked at 6 PM EST, and there wasn't anything for Madden. Then I checked again at 9, from what I thought was an overabudance of caution, and found an active drop campaign for Wed, Jan 28, 6:55 PM - Wed, Jan 28, 9:29 PM EST. But it seems like the official Madden channel is the only channel that qualifies for the drops, and that channel stopped streaming two hours ago. So apparently more like 6:55 to 7:40? I don't think I'm ever gonna get into the habit of checking Twitch every 40 minutes, so the only way I would ever know about something like this is to be told about it in advance. 

End rant; the question again is, how do I found out about these extremely short Twitch drop campaigns in advance?
