Dear Tom,
Is it true that Chicago had twice as many days of 80 degrees or higher in 2007 than we have had this year?

Dear Pat,
This year's lack of warm days has been extraordinary. So far in 2009 Chicago has logged only 56 days at Midway Airport where the mercury has reached at least 80 degrees. That is the lowest total there since records began in 1928, besting the previous record of 58 days during the cool summer of 1992 when volcanic haze from Philippine volcano Mt. Pinatubo reduced temperatures world-wide. Ironically the year with the most days of 80 or higher was one year earlier in 1991 with 108. In 2007 the city reached 80 or higher 103 times falling a little short of doubling this year's anemic number.
