During the storm the will be bedded up in the thickest heaviest cover they can find. As soon as it lets up or stops they will be out feeding like crazy. I have hunted a number of snow events here in VA over the years, both down here in this region and up in the mountains and they always react the same around here.
Tomorrow will not be the best day to hunt, today will be excellent as they will be on their feet feeding like crazy and then again on Monday will be good as well too.
I am sure there will be some deer moving tomorrowing but not alot, just like a heavy rain.
