Plot Description:

This plot presents the trailing X number of days temperature or precipitation departure from long term average. You can express this departure either in Absolute Departure or as a Standard Deviation. The Standard Deviation option along with precipitation is typically called the "Standardized Precipitation Index".

The plot also contains an underlay with the weekly US Drought Monitor that is valid for the station location. If you plot a climate district station, you get the US Drought Monitor valid for the district centroid. If you plot a statewide average, you get no USDM included.

Based on a sampling of recent timings for this application, plot generation time has averaged 5 seconds. Hold on for the plot is generating now!
