Plot Description:

This application creates two 2-D histograms of GDD accumulation frequencies. These frequencies are based on historical data for the specificed site and base the end of each year's growing season on the first sub freezing temperature of the fall. The left hand plot shows the overall frequency based on each year's data. The right hand plot does a scenario using the combination of year to date data for this year and then each previous year afterwards is appended to this year's data to provide frequencies. The right hand plot is meant to provide current frequencies / probabilities of what could potentially happen this year.

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!
