Plot Description:

This application generates heatmaps of Storm Prediction Center convective outlooks.

Major Caveat: Due to how the IEM stores the outlook geometries, the values presented here are for an outlook level and levels higher. For example, if a location was in a moderate risk and you asked this app to total slight risks, the moderate risk would count toward the slight risk total.

This autoplot currently only considers outlooks since 2002.

Based on a sampling of recent timings for this application, plot generation time has averaged 24 seconds. Hold on for the plot is generating now!
