Snow forecasts don't affect pheasant hunting. Snow does. Some people claim tracking birds in snow is effective. I haven't noticed that in 40 years of hunting (not that I've never done it). My recommendation would be to not be concerned with it. Typically, this time of year, snow doesn't change much because the snow's usually not deep, doesn't last long, doesn't knock down other types of cover, & doesn't make feeding difficult. When it affects things is when it completely covers everything except the thickest cover. Birds won't stay out on the barren tundra any longer than it takes to scratch around for food to fill their crops, because when they're out there, they're completely exposed to predators, particularly birds of prey & humans. When the lighter cover just has a blanket of snow over it, they'll still use it. But when it's completely socked in w/ snow, they'll head for the thick stuff, typically cattails. And during the day they'll hang out in trees more, particularly if it's windy out. After there's a good 6-10" of long-lasting snow on the ground, they'll relate to roosting cover, food, loafing cover, & safety cover, & they'll just hop back & forth between them. I believe roosters feel safest during the day in trees. (Nighttime is different because....owls) If things are pretty tough (cover-wise), the roosters will often kick the hens out of the best cover. I've found this to be mostly true during the day. At night, they both sleep in cattails or buried under some nice, soft, snow-covered grass or cedar trees.
