Using NOAA data (mean temperature), how cold are the last 12 months (Jul 2011 to Jun 2012) compared to the warmest month.
For example, October 2011 in Alabama was -13.6F colder than the warmest October in Alabama – 1919
October 1919 was 74.0F
October 2011 was 60.4F
Current Temperature minus Record Temperature
If the value is 0, the record for the mean temperature was set in the current month.
