Extreme Heat and Dryness at Dodge City (updated 9/21/11)

Like much of western and south central Kansas, the extreme drought continued as the meteorological summer ended at Dodge City.  In addition, extreme heat experienced during the summer did not let up.  It's definitely been a record setting year at many locations, including Dodge City.

Meteorological summer includes June, July and August.  For these three months, daily high temperature records at the Dodge City airport were broken 14 times and tied 7 times.  This is a phenomenal occurrence!   There were 9 daily high temperature records broken or tied in August alone.  Since January 1st of this year, daily high temperature records were broken or tied 27 times!

The average daily temperature for the summer at Dodge City was 83.5 degrees and this is the hottest on record (since 1875), well above the normal of 77.2 degrees.

Normally during the summer we can expect around 13 or 14 days of 100 degrees or hotter at Dodge City.  However, this year that number occurred way too frequently.  As of September 6th, the high temperature reached 100 degrees on 54 days which obliterates the previous number of 42 set in 1934!  Another record?  How about the number of 90 degree days?  Yes, that was also a record, not only for the summer, but also for the year.

The heat wasn't the only story for the summer.  The drought across much of the area had become exceptional across much of the area. As of August 31, the following map depicts where the drought was occurring...

As of August 31 it was also the driest start to the year! The following graph shows the top five driest starts to the year.  Notice all the previous years ended up well below normal by the end of December.

Comparing this year to the top driest years ever observed at Dodge City, 2011 is well behind, which does not bode well.  It will take significant precipitation the remainder of 2011 to even get close to the driest year on record which was in 1893 when only 9.97" fell.
