Issued the first Severe Thunderstorm Warning of the afternoon for far Northeastern Counties in LSX for a marginal Severe Thunderstorm. For the scan when I initiated the Severe Thunderstorm Warning, it was up to 60% Prob Severe with 0.83" MESH Hail with close to 54 DBZ at 21K Feet. Felt it was enough that it could drop quarter sized hail, so pulled the trigger for a Severe Thunderstorm Warning for hail and torrential rainfall out of this thunderstorm. Very borderline, but judgment call for Severe Thunderstorm Warning, as it was intensifying from 20% to 60% Prob Severe within 3-4 radar scans.

Continued Severe Thunderstorm Warning for this storm for marginal 1.00" hail threat and heavy rainfall, but one thing noted, cell is looking like it is splitting as it moves off to the Northeast, but Prob Severe has continued to treat it as one thunderstorm. As noted in thunderstorms on Tuesday in Oklahoma, the right one has become the dominant thunderstorm, that appears to be the case with this storm as well.
SECOND WARNING:

Issued second Severe Thunderstorm Warning for the same cell, as some weakening then, re-strengthening has occurred with this storm. The Prob Severe has gone the highest we have seen with this, with 71% and 0.89% MESH, so continued same hazards with this storm, as I have with the previous storm.
And then with the following scan, Prob Severe jumped to 88% with 1.09" MESH Hail, so this storm was intensifying as we we're going along...
