Comparison of ProbSevere and Custom DTA

After setting up the custom Thunderstorm Alerts (75/min and 100/min), there were a couple areas of focus on the 100/min alerts (to the west-southwest and southwest of KTLX).

The storm to the WSW only had a ProbSevere around 11% (that had the greatest flash rate around 149 per min), while the storm to the SW had a ProbSevere of 88%, but a weaker flash rate (87 per min).
