ASK TOM: Has Chicago ever had two consecutive days on which the high and low temperatures were the same on both days?

Dear Tom, 

Has Chicago ever had two consecutive days on which the high and low temperatures were the same on both days? For example, the high and low on the first day and also on the second day were 76 and 50 degrees.

Dear Dan,

Chicago’s weather is known for its variability, and changeable temperatures are the rule rather than the exception. Occasionally, though, a day’s high and low temperatures will be replicated on the following day.

 

It happens more often than you might think. A computer sweep of Chicago temperatures from 1871 to 2012 reveals 294 pairs of days with identical maximum and minimum temperatures.

 

The most recent event was March 24-25, 2011, each day with high/low temperatures of 34 and 24 degrees.
