Plot Description:

This chart attempts to assess by now much the high temperature can change between two or three periods of time. These periods are defined by the consecutive number of days you choose. The tricky part is to explain what exactly these periods are! The middle period of days includes 'today', which is where this metric is evaluated. So a middle period of 1 days only includes 'today' and not 'tomorrow'. If you summarize this plot by year, a simple linear trendline is presented as well.

A practical example here may be warranted. Consider a period of four days whereby the warmest high temperature was only 40 degrees F. Then on the next day, the high temperature soars to 60 degrees. For the plot settings of 4 trailing days (Maxiumum) and 1 forward days (Whatever, does not matter for 1 day aggregate), this example evaluates to a jump of 20 degrees.

Based on a sampling of recent timings for this application, plot generation time has averaged 2 seconds. Hold on for the plot is generating now!
