There should be a snow equivalent to the wind chill factor. Obviously, five inches of snow is much worse in Dallas than Minneaopolis. People up north have much more experience and equipment and handle snow much better. I spent my first 10 years in Manhattan and we always went to school in the snow. I have lived in Baltimore since 1976 and I will never get used to how badly they deal with snow here. They would close schools on a rumor of snow.
