Plot Description:

This autoplot lists out daily climate observation extremes for a given combination of variable threshold and day offset. For example, you can ask for days with measurable snow cover, what was the top 10 warmest and coldest high temperatures on the day following. If the second variable picked is precip, snow, or snow depth, the lowest 15 values are not plotted as they are often zero and not as interesting to look at.
