Plot Description:

This chart presents the accumulated frequency of a temperature threshold being the first time observed or last time observed during the fall season. There is a complexitiy to the last time metric as it is somewhat undefined as to when the fall season ends and the next spring/summer season beings. So life choices are made here:

For first below, the first date that the temperature happens is considered between 1 August and 31 May of the next year. This is generally straight forward.

For last above, the last date that the temperature happens is considered between 1 August and 31 December of the same year. This is nebulous for temperature thresholds that are common throughout the cold season. Caveat emptor.

Autoplot 120 is closely related to this autoplot and presents the spring season values.
