Assessing LightningCast in Ongoing Convection

In the Tallahassee CWA, convection was ongoing at about 21z over the western portions of the Florida Panhandle.  In order to get a quick assessment of the convective trends, loading up LightningCast with ProbSevere and MRMS radar is a good start. A loop is provided in Figure 1 below.

I noticed in southeast Alabama into southwest Georgia that LightningCast was teetering back and forth between the 50 and 75 percentile contours.  LightningCast even went down to the 25% contour for a brief stint at 2041z.  Looking at NLTN data, there was certainly plenty of lightning left within that storm, so I couldn’t quite understand why it went down but then pulsed back up. The other issue I ran into is the contours suggesting lightning, but convection is nowhere near the 75% contour (See Figure 2).
