I doubt that affiliates had any kind of a regular schedule because much of their news typically wasn't of interest outside their coverage area. For events that were known to be coming (including major storms), it is more likely that the network sent out a team rather than using an affiliates coverage.
It is a fool's errand to insist that something must have been happening when there's no compelling reason for it to have been happening. You've tried to build a case on a daily need to get information out to the region or nation when that simply didn't (and still doesn't) happen that frequently.
