Graphic Output
 Earliest - Earliest 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 July 31 to 
                  Dec. 31 period or insufficient data to determine a date.
            07/31 means the minimum temperature can go below the threshold 
                  temperature any day during the July 31 to Dec. 31 period.
xx% - Percent probability that a minimum temperature below the threshold will occur on or before 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 been a year when the minimum temperature didn't go below the threshold temperature during the July 31 to Dec. 31 period or insufficient data to determine a date.
