Plot Description:

This chart presents a simple accounting of the percentage of first order NWS climate sites that are either above or below average or reporting precipitation / snow each day. Note that no spatial weighting is done, so one should not interpret this as an areal coverage of some condition. For temperature, sites with an average temperature for that date are omitted.

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!
