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.
