The rut happens every year at the same time. Because you aren't seenig it doesn't mean it isn't happening. It winds down at the same time each year. Weather has no effect on the rut. Snow on the ground simply makes the deer easier to detect.
God has equipped his creation to know when the optimal time for breeding to occur each year, so the fawns will be born with the best chance for survival. He has also equipped the wary old bucks with a strong sense of self preservation, which gives them the instincts to know that low light conditions, that is, early morning and early evening gives them the best chance to avoid detection from human predators.
If there are unbred does in your area, that is where the bucks will be. Most does will have been bred by now but the bucks will travel far and wide to find those that are still in estrus.
