1-minute GOES-16 Visible and Infrared images with\/without an overlay of GLM<\/strong><\/a> Flash Extent Density<\/strong><\/a> (below)<\/strong><\/em> revealed that the easternmost supercell thunderstorm tended to exhibit a bit more lightning activity. These severe thunderstorms developed just to the north of a quasi-stationary frontal boundary that was draped across North Texas.<\/p>\n
