First Lightning Along in south Central SD

By 1951 storms have initiated over the area of interest with the first GLM flash occuring at 1951 UTC,  coinciding with first 50dbz echo from FSD at 1952 UTC.

First CG strike was detected at 1957 UTC with the GLM giving 6 minute lead time before the first strike.  Note that the parallax error causes the data to be shifted east of the CG location, which could cause some misinterpretation of the data.
