Having been to Chi-town in the winter, I would have thought the
records were a lot lower than that.

Everyone who grew up in Chicago remembers, when he was a child, when the temperature
didn't go above zero for a week. Bill Klien said "I also remember when we would
have multiple days in a row when the temperature never got above zero."

A book "The Weather and Climate of Chicago" by Henry Joseph Cox, John Howard Armington -
1914 says:

"Table XXXI gives the longest period when daily maximum temperatures of zero or lower were
recorded. In only 5 of these 14 years were there 2 consecutive days, and only one year
where there were more than 2. That was in 1883, January 21 to 23."

page 76

However, I found this confirmation of Bill's assertion:

"Chicago's longest zero spell: 100 hours (four days, four hours). Beginning at 7 a.m. on
December 22, 1983, and continuing through Christmas Eve and Christmas Day to 11 a.m. on
December 26, Chicago's temperature remained at or below zero for 100 consecutive hours,
the longest frigid spell in the city's history."

My take: Consecutive sub-zero days are rare. People tend to exaggerate.

If you want cold, go to Duluth or International Falls MN, where the NORMAL AVERAGE January
low is -20 and the record is -45. They're having a heat wave right now, it's 7.

Given that people can live anywhere they want, why does anyone choose to live in Duluth?
