Year-to-Date Temperature Evolution
This time series shows the 2012 year-to-date temperature through November, which was the warmest first eleven months of any year on record for the lower 48. The year-to-date evolution of the contiguous U.S. temperatures for each year back to 1895 are also shown, with the five warmest and five coolest years highlighted. The January-November 2012 contiguous U.S. average temperature was 57.1 °F, 3.3 °F above average. The data for 2012 are preliminary.

This time series also shows the 2012 year-to-date temperature through November. Outcome scenarios based on persistence of temperature for December, the remaining month of 2012, are shown. The January-November 2012 contiguous U.S. average temperature was 57.1 °F, 3.3 °F above average. The nationally-averaged temperature for December 2012 would need to be more than 1.0 °F colder than the coldest December (1983) for 2012 not to be the new record warmest year. The data for 2012 are preliminary.
