If the core of the wood is still wet, then moisture will still be migrating from the core to the surface. So if the fans and "heat" are off, that moisture won't be evaporating, and so the MC of the surface would increase slightly.

As Ianab said, the case and core have probably not equalized, so there is migration of the core moisture to the case. 
The best, least expensive, most accurate moisture meter is using the oven dry method.  It utilizes a cheap food scale and a microwave or conventional oven.

I picked up this Air Switch at the Flea market today. I'm going to use it to turn on/off my fans when the temp drops.

The air switch I know about uses air pressure from a push button to turn on an electrical switch.  You can do this with wet hands.  It was popular before gfi. This looks different...can you explain?  Please.
