I remember back in the day the network aired pre-recorded studio coverage from 2-5AM ET, which was essentially a loop of the 2AM hour. If the network does indeed go weather 24/7 I could see this as a possibility again. Better yet, they could air a continual loop of maps / radar set to background music and then add in LOT8s. Of course if there is severe weather they would go live.
Trying to predict what TWC will do with its schedule is akin to predicting a hurricane track. This next month will be an interesting one for TWC fans.
