Might slow down mid day movement a little. Looks like a cold front moving in after Saturday though, high of 41 on Sunday. Should be good hunting both days. I guess in my book there is no such thing as bad hunting.
Weather is only going to mess up a does' cycle only so much. When they are ready to breed, they are ready. Don't matter if it's 70 degrees or 30. When they are ready, it's time to be in the woods. And hey, who wouldn't want to actually be warm in their stand or blind when the rut is cranked up. Sure beats freezing your ass off.
I don't think it affects their cycle at all, but I do think it affects the movement you see during the daytime.
But I agree....all things being equal I'd rather be comfortable than frozen! :way:
