I grew up in Ohio in the 1970s (which was admittedly a rough decade as far as cold weather was concerned). Generally, the first snowfall was some time in September and at some point in October the ground would be completely covered in snow and you wouldn’t see grass again until April. The snow wasn’t completely gone until May. So essentially it was six months of Winter, three months of Summer and a month and a half each for Spring and Fall. It is certainly not anything like that any more.
