Winter

So much for Chicago's unusually balmy winter this year. I had to walk to a lab on 57th street a few minutes ago. This, of course, necessitated walking across the Midway. During the winter, the long and open expanse of the Midway essentially acts as a wind tunnel from inland parts of the city to Lake Michigan. When I checked the weather upon my return, NOAA was reporting a temperature of 2 degrees F with winds of 25 miles per hour. Given the nature of the Midway, the winds there are probably even higher, resulting in an effective temperature (post wind chill) of less than -22 degrees F.
