ProbSevere Double Contour

A quick post regarding the ProbSevere 'double contour'.  New to the ProbSevere AWIPS-II display is an outer contour that indicates the ProbTor value for a storm outside of the inner contour (the inner contour is the maximum of ProbHail/ProbWind).  This double contour idea came from the forecaster feedback from the 2018 HWT experiment--as a means to have both severe thunderstorm warning and tornado warning guidance in a single display.  Today, forecasters have very active weather, with many storms (Figure 1).  The default for the double contour to appear is ProbTor >= 3%.  Forecasters have stated today they appreciate the ability to change the threshold for the double contour to appear.

Figure 1.  ProbSevere contours from a forecaster's AWIPS-II screen.  The inner contour is the maximum of ProbHail/ProbWind for the storm and the outer contour is the ProbTor value (displayed when ProbTor >= 3%).
