If you dont' like Chicago weather, wait a minute

Two days before I took this picture (1.19) it was so nice out. I was walking around with just a sweater, sport coat, and scarf.

The next night, it snowed about 4", and then just got cold.

The day I took the picture, the sun was out and it was getting warmer. Of course, this meant that the snow began to melt, leaving slushy puddles of dirty water everywhere. Then, when the sun went down, it all promptly re-froze to ensure that walking and driving was as hazardous as possible.
