Well I'm far from an expert, but I have killed about 15 of them in the last 12 years or so and called in probably another 15 for others. From what I've seen, there really isn't any "bad" weather for turkeys. If it's raining, I'll setup a blind and decoy spread and stay dry and have killed a few this way. They seem to head to the fields when its raining/snowing, or so windy enough that their eyes/ears aren't able to detect danger in the timber.
The only thing I've seen that really affects behaviour other than heading to open places like this is fog/rain/cloudy days seem to make them come off the roost later.
Very well stated. I also notice just right after it rains they really hit the fields to dry off their feathers.
