Graphic Output
 Earliest - Earliest date when a minimum temperature below the threshold occurred.
            **/** means there has been a year when the minimum temperature didn't
                  go below the threshold temperature during the Jan. 1 to July 31 
                  period or that there was insufficient data to determine a 
                  date.

xx% - Percent probability that a minimum temperature below the threshold will occur on or after the given date. **/** means non-occurrence of the threshold or insufficient data to determine a threshold.
Latest - Latest date when a minimum temperature below the threshold occurred. **/** means there has never been a year when the minimum temperature went below the threshold temperature during the Jan. 1 to July 31 period or insufficient data to determine a date. 07/30 means the minimum temperature can go below the threshold temperature any day during the Jan. 1 to July 31 period.
