Automated Data Plotter
This application dynamically generates many types of graphs. These graphs are derived from processing of various data sources done by the IEM. Please feel free to use these generated graphics in whatever way you wish.
Second, select specific chart options::
Plot Description:This application has a considerable and likely confusing amount of configuration options. In general, it will produce a map of either a single NWS Weather Forecast Office (WFO) or for a specified state. For warning types that are issued with polygons, you can optionally plot heatmaps of these products. Please be careful when selecting start and end dates to ensure you are getting the plot you want. There are likely some combinations here that will produce a broken image symbol. If you find such a case, please email us the link to this page that shows the broken image!
Storm Based Warning polygons were not official until 1 October 2007, so if you generate plots for years prior to this date, you may notice polygons well outside the County Warning Area bounds. There was no enforcement of these unofficial polygons to stay within CWA bounds.
This app can be very slow, so please let it grind away as sometimes it will take 3-5 minutes to generate a map :(
Based on a sampling of recent timings for this application, plot generation time has averaged 99 seconds. Hold on for the plot is generating now!
