Chicago-style spring equinox

The spring equinox is today.

Yesterday's warmth and the combined heat of 10 sleeping bodies and three working radiators in the apartment tricked me into thinking that today would be a weather-nice day.
I walked out of the house wearing thin canvas shoes and no hat, looking forward to my morning walk to the L.
I walked out of the house into snow and was shocked.

A couple houses down the street, a woman bundled in crocheted warmth was sweeping snow from her steps. As I walked by she cheerily called out, "Happy Spring!"

Later, as I walked over the bridge on Michigan Ave., the wind tried to push me into traffic.

This is ridiculous.
