Weekly magazines often appear in doctors offices and in mailboxes of consumer home subscriptions many days before their ascribed "newstand date." (newsweek, time magazine, national geographic, the economist... )

Note the qualifier "ISSUE," which would hint that it's not a daily.

For weeklies, editors probably have their print runs prepped for the publishers a few weeks in advance, with some variable slots left ambiguous for flexibility, in case they want to pre-empt a soft story with significant breaking news.

This piece doesn't seem to be a run up of current events, like the latest Trump tweets or whatever active shooter incident du jour. It's really a research piece that probably took several months to compile, edit and sweeten. Figure the broad strokes and the idea of the article were crafted over the summer, maybe.
