Dear Tom,
How many Julys and Augusts have failed to record a 90?
Norman H. Jannusch, Schaumburg
Dear Norman,
Using the city's official station weather records which began in 1871, Chicago has recorded only six Julys that failed to produce a high temperature of at least 90. This July stands to become the seventh and the first since 2000. Augusts without 90s are a little more common here, having occurred 16 times, most recently in 1986. Further checking reveals that there have been only two years, 1875 and 1915, where neither July nor August recorded a 90. In fact, 1875 is the only year that failed to produce any 90s at all. It looked like 1915 would become the second such year, but a late-season temperature surge pushed the mercury to the elusive 90-degree mark on Sept. 14 for the year's single occurrence.

I am extremely weather sensitive & seem to be growing more so with every year. Approaching low's seem to inflict the most pain on me. Are there any areas of the country that are more stable - ie that have fewer low fronts passing through - than the Chicago area?
Hi Tom,
Could Illinois have a mild winter?
