Warmest Spring on Record for US

The U.S. is well on its way to crush the record for warmest spring since national temperature data began in 1895. Here's an indication of just how far that record could go. The previous record spring in 1910 had a national average temperature of 55.1°. However, the March 2012 temperature exceeded March 1910 by 0.5° to set a new record for the month. April 2012 then exceeded April 1910 by 1° (see the charts to the right).
