In this FDTD GOES Applications Webinar, the Huntsville NWS office discussed the history of total lightning data usage at the HUN NWS Office, and described the usage of GLM data during a couple of recent severe weather cases. On December 16, 2019, the GLM data were used to diagnose severe convection in a moderately unstable environment. On January 11, 2020, GLM data factored heavily into warning decisions for severe convection, including tornado warnings, when their primary radar (KHTX) failed.
Below is an example of how GLM data were used in messaging during one of the events:
“Once the storms entered Marshall county, we really started to see an uptick in lightning activity, the strongest that we had seen that day. So we got on the radio and social media, and said, ‘we are really confident this storm is rapidly intensifying, something can happen here, … people in the path really need to be taking shelter right now.'”
