I' d agree with Turkey Addict on the hot days in Wisconsin/Minnesota. They sometimes gobble a little right at first light and then you' d swear there wasn' t a bird in the county.

When it rains really hard and the wind is heavy (Gale force) I stay in the truck as I' ve never had much luck then. It make sense as the trees are moving around so much and the wind so strong that they can' t use their senses to detect danger and I think alot of them just fly up to roost until it passes. I did take a gobbler this year in Wisconsin after it had rained all night but had quit by morning. It was a little windy but not excessive and I figured they' d be out feeding and drying off as well.
