Highest Flash Event Densities Collocated With Updraft Location

[23:00 UTC] Have tried to overlay semi-transparent GLM data over GOES-East meso-sector visible imagery and the results are pretty useful. For one, the highest flash event densities seem to be collocated well with perceived updraft location (overshooting tops are being used as a proxy), which fits the conceptual model of what one would expect. It should be noted that the values themselves were not quite as useful as seeing the change in the values and the "peaks" in values which were highlighted a bit more by altering the color scale. This certainly is useful in an operational setting in terms of isolating the most important (rapidly developing) updrafts in a quick and timely fashion.
