Graphic Output
 Shortest - Least number of consecutive days recorded with minimum temperature 
            above threshold.
            *** means minimum temperature below threshold has not occurred.

xx% - Percent probability that a consecutive number of days will occur with the minimum temperature not below the threshold. *** means non-occurrence of the threshold
Longest - Greatest number of consecutive days recorded with minimum temperature above threshold. *** means that at least one year occurred when minimum temperature below threshold was not recorded. Note: All periods include August 1.
