I’d lay the cupped board on the dirt floor, with the cup down. The moister from the floor may help bring it back.

I’d also try to store the lumber as far from the floor as you can. If you plan to do a stack like David suggest, add a layer of plastic under, but not directly under the stack.

The problem goes beyond storing your lumber. Buy an inexpensive moister meter (lowes has them for about $30) and see what the content of the board is to start with, and what your shop is. It sounds like the moisture content in your shop is high, but you should know that for sure.

My shop has a concrete floor and a tin roof. If I store lumber on the first floor the average content is 11-12%. If I move it to the attic it drops to about 9%. Do some testing like that. See were the best spot in your shop is (if there is one)

The point is, you’ll need to plan for drastic wood movement after you’ve built your project and move it to your house (or anybodies house). Its one thing to have a piece of lumber ruined by movement, its another to have a project ruined by it.
