Despite all the national media blitz about warming, the fact is that mean temperatures for the June-August period of meteorological summer 2012 ended up very close to longer term averages.  

This was not a local aberration, with weather stations in the adjacent foothills of eastern Kentucky reporting the following summer 2012 temperature means and departures from average.

Summer MEAN Temperature
( Departure From Average )

Jackson, Kentucky: 74.7 degrees 
( +0.7 degrees )

London, Kentucky: 74.7 degrees
( -0.1 degree )

Summer MEANS ended up being exactly the same at both Jackson and London, with departures varying from only 0.1 degree below average in London to 0.7 degrees above average at Jackson.

All-time record heat was an outstanding event during late June, with the highest temperatures ever documented being observed across nearly all elevation ranges in the mountain area.

Summer 2012 - From Chilly To Extended HEAT

This anomalous heat burst actually came at the end of a June which had featured cooler than average conditions.  The June MEAN of 67.4 degrees in Wise, for example, ended up 0.4 degrees cooler than the 1955-2011 June average ( * ).

*Based upon National Climatic Data Center official average for Wise 1 SE and Wise 3 E.  This occurred despite consecutive 95 degree maximums on June 29-30 which were the highest official temperatures ever observed during any month in Wise.

A very wet July followed with above average temperatures that were essentially canceled by below average August temperatures, subsequently the Summer 2012 MEAN temperature came out being around the long-term average!

Wayne Riner Photograph Thoughts...
"This is the moonrise of August 31, 2012, making it a "blue moon".  It is called that for it is the  second full moon in the same month. The next blue moon will be in July of 2015.  The moon is slightly obscured by a thin high altitude cloud, causing it to look out of focus."
