It has been a very active day with storms over our warning area.  The Prob. of Severe tool really helped me focus in on the storms that were more intense and then I was able to use Dual-Pol info to help verify and issue the warnings.  I was able to observe that the Prob of Severe as it followed the strengthening and thus weakening of the individual storms.  As you can see from above…when they turned the hot pink color..is normally when I was issuing the warning and actually allowed the warnings to expire when they started to drop down to the gray color.  This also verified with storm spotter data so I find this tool very useful and I really like it. ~Vollmar
