Plot Description:

This application attempts to assess the effectiveness of a calendar day's rainfall based on where the rain fell in relation to a previous period of days departure from climatology. So for a given date and state, the areal coverage of daily precipitation at some given threshold is compared against the departure from climatology over some given number of days. The intention is to answer a question like how much of the rain on a given day fell on an area that needed it! The areal coverage percentages are relative to the given state.

Based on a sampling of recent timings for this application, plot generation time has averaged 4 seconds. Hold on for the plot is generating now!
