pLGM Lightning Data

We are finally in a CWA with pLGM lightning data today and the network is actually working! Convection hasn't been all that impressive so far today, but we did have one cell that produced a pea-sized hail report. The report was from Davidson County. The pLGM lightning flash extent imagery showed a spike to around 30-40 as the cell entered Davidson County. The LMA_1 color table highlighted this jump the best, I thought.

We also noticed the ProbSevere algorithm jumped rapidly from less than 10% up to 80% in less than 10 minutes around this time. This jump seemed to be mainly triggered by the increase in lightning activity. Luckily, we did not pull the trigger on a warning based on the ProbSevere algorithm, because the storm weakened again pretty quickly after this. The shear environment is fairly weak and does not seem able to support anything other than pulse cells at this point.
