That's how I currently have them stored, my only concern is temperature and humidity

As long as you're not storing them in a sauna you should be fine.

Volod, I'm guessing those sleeves are polyurethane, not polyester

Most of my sets were put together in the '80's, when storage materials were still relatively cheap, so at that time, polyester (mylar) sleeves could be had by the K for about six bucks or so. I don't know if they are even still available these days - but polypropylene, which is what I believe you mean, is almost as clear, though not as archivally approved.
