BEST - Why no cooling in the Southeast?

I originally wrote this as a comment on WUWT.

There are six states which have a negative trend from 1895 as of the end of 2011. Alabama, Georgia, Mississippi, Arkansas, South Carolina and Tennessee.

Here is an example of Alabama’s NOAA data graphed.

BEST didn’t find any negative trends.

It even gets discussed in papers.

“It is shown that the SE United States is one of few regions on this planet that shows a cooling trend over the twentieth century (Trenberth et al. 2007). Portmann et al. (2009) find that this cooling trend is strongest in the late spring–early summer period.”

Even the South Carolina State Climatology Office recognizes it.

“Research suggests that the temperature of the southeastern United States has been decreasing over the past 100 years. The Southeast is distinct from other regions of the United States that do show distinct warming. Cooling in the Southeast, however, is not necessarily due to recent temperature trends. Rather, the large scale cooling is readily apparent when looking at the extended period of record. Temperatures in the early 1900s were generally cool then warmed between the 1920s and the 1940s. Starting in the 1950s, temperatures decreased until the 1970s when a general increase in temperature began. Because of the warming in the 1920s through 1940s is greater than the warming after 1970, the overall trend of the century is a cooling trend.”

 
How could BEST not find a cooling trend when a lot other people can?
