Louisville's historically hot summer AND temperatures at Bowman vs. Standiford Field

I hit this earlier from one angle (number of above-normal heat days)-- and in a comparison to previous key weather events.

Now, from Chris Quay in the C-J, setting a record in terms of average temperatures.

According to the National Weather Service, the average temperature — which factors in daily highs and lows — during its June-through-August summer period was 82.5 degrees.That's a full 11/2 degrees hotter than in 1936, the previous hottest summer. And it's about 6 degrees above normal for the period...

Nathan Foster, a meteorologist with the weather service, said the main reason for the extreme heat has been high-pressure systems that lingered over the Ohio Valley.

Meanwhile, John Belski notes the significant difference in temperature readings between Bowman Field and Standiford Field, five miles away. (Hat tip: Linda Christiansen. On a related manner, I've blogged previously on the potential for bias in temperature readings over time.)

The average temperature for the summer at Louisville Int'l (SDF) was 82.3; Bowman 80.6.

The SDF temp makes this the hottest summer in Louisville history beating the 1936 temperature of 81.0; Bowman's reading...if it was official...would have been the 2nd hottest.

100 degree days... SDF: 4; Bowman: 1

90 degree days: SDF: 69; Bowman: 52.

That is a pretty big difference of 17 days over just a 5 mile distance. You can conclude whatever you want on this....most of you know my feelings.

I imagine the difference between the two airfields is that Bowman is smaller, and surrounded by leafy neighborhoods—trees cool the air through transpiration.

I'd guess that it's the surroundings as well...
