The National Weather Service says 2009 has seen the coldest July since the official recording station was moved away from the lakefront in 1942. The average temperature this month in Chicago has been a mere 68.9 degrees.
Even in the years before 1942, when the National Weather Service recorded temperatures at the cooler lakefront, there are only three years that had colder Julys through the 26th.
They have not hit 90 degrees yet this month. One wonders what things like the moving of the official recording station have done to the statistics – and how much effect that has had on the projections.
