May 8 Evaluation of Test Products in AWIPS2

Area just north of main convection rapidly strengthened (lightning via glm, overshooting top in visible, high dBZ core in MRMS shown below)

Area just north of main convection rapidly strengthened (lightning via glm, overshooting top in visible, high dBZ core in MRMS shown below)

High dBZ core situated away from main convection, noted by large cloud flashes via ENTLN

CI product showing the scarcity of the likelihood of newly-formed storms in central IA in the near future

CI product showing the more unstable environment in SD, indictaed by several isolated storms showing high lightning rates and high dBZ cores

ProbSevere model showing increased probabilities (30-40%) of storms becoming severe in SD

ProbSevere doing a good job at helping locate storms of interest for further investigation in addition with spatial extent of GLM FED

GLM total energy looks to better identify storms with higher ProbSevere hail potential (top right panel, storms in SD).  However, GLM FED does not correlate to total energy, in fact, the storm in northwest IA exhibits a larger FED, but lower flash energy than the storms in SD.  In fact, the ProbSevere wind potential is the main threat for this storm.  I.e., differentiation between flash energy, flash rate, and hail/wind threats.

strange non-meteorological GLM feature appearing east of Florida/Bahamas

ProbSevere and ltg nicely capture the evolution of this storm in north-central SD to  its growth, most intense phase, and decay
