March of 2012 will go down as the hottest March in recorded history for Middle Tennessee in a month that shattered all previous records.“Temperatures for March 2012 were the warmest since recording keeping was started in Nashville by the Army Signal Corps way back in 1870,” said National Weather Service meteorologist Bobby Boyd from the Nashville Bureau. “The temperature for March 2012 averaged 61.1 degrees, which is 11.1 degrees above normal.”Boyd said this March broke the long-standing record for the hottest March, which had stood since 1907. Ironically, the next month in 1907 saw the coldest April on record.However, Boyd foresees no such turnaround as long-range forecasts call for temperatures to be warmer than normal and for there to be more rain than average.The average temperature for this March was 73.4 degrees and the average low was 48.8 degrees.
