September 2012 Statewide Temperature Rankings


 
From NCDC:  September 2012 Climate Summary
 
  • Climate Highlights — September 2012
  • The average contiguous U.S. temperature during September was 67.0°F, 1.4°F above the 20th century average, tying September 1980 as the 23rd warmest such month on record. September 2012 marks the 16th consecutive month with above-average temperatures for the Lower 48.
  • Higher-than-average temperatures were anchored across the West during much of September with California, Nevada, Utah, and Wyoming experiencing a top ten warm September. Monthly temperatures were below average across the Midwest and Ohio Valley.

  • Nebraska was ranked 67th coolest (which is conversely, 45th warmest) September on record (118 years of data, 1895-2012).

    HPRCC Highlights:
  • High Plains Region: (Information provided by the High Plains Regional Climate Center)
  • While most the High Plains Region had near normal average temperatures, September 2012 continued to be dry. Most locations in the Region had average temperatures which were within 1.0-2.0 degrees F (0.6-1.1 degrees C) of normal. The largest temperature departures occurred in a few areas of Wyoming, where average temperatures were over 4.0 degrees F (2.2 degrees C) above normal, and an area along the border of northeastern Kansas and southeastern Nebraska where average temperatures were 2.0-3.0 degrees F (1.1-1.7 degrees C) below normal. Unlike the majority of this year, the temperatures this month were not record setting; however a small number of locations did break into the top 10 warmest Septembers on record. Lander, Wyoming had its 6th warmest September on record with an average temperature of 63.2 degrees F (17.3 degrees C). In 1990, Lander had its warmest September with an average temperature of 64.8 degrees F (18.2 degrees C) (period of record 1891-2012). Even with some below normal temperatures this month, 2012, as a whole, has continued to be one of the warmest on record for much of the Region. For instance, the average temperature in Topeka, Kansas was 0.5 degrees F (0.3 degrees C) below normal this month, but this year's January 1-September 30 time period still ranked as the warmest. The average temperature in Topeka for that time period was 64.4 degrees F (18.0 degrees C), which easily beat the 1934 record of 62.3 degrees F (16.8 degrees C) (period of record 1887-2012).
