from what I have seen no if there's food that eat in light rain mid rain. don't know about thunder storms never got out with my lighting stick and glassed in that *censored* wate it out in the truck when that rolls in
the best way to know is to just go do it. for 1 ok spot iv found I hunted and scouted 20 for my grouse honey holes I put down miles and miles with the dog. what I'm trying to say is go hunt the rain snow sun wind what ever if it works. go bear hunting find a good deer spot go grouse hunting find bears.
