Plot Description:

This plot displays the period of consecutive days each year with the extreme criterion meet. In the case of a tie, the first period of the season is used for the analysis. If you select any of the warmest options, the year must have at least 200 days of data.

The dew point and feels like option only works for ASOS networks and does a simple arthimetic mean of dew point temperatures.

Note that the coldest and warmest feels like temperature values are averages of the daily minimum or maximum values, not an average of an average feels like temperature. This is why we can't have nice things.
