The overshooting tops of these intensifying storms began to penetrate the anvil debris of pre-existing convection after about 2330 UTC in the Monett KHFJ area, with an above-anvil cirrus plume becoming evident after 0000 UTC. The 0025 UTC image showed yet another new cell which had recently developed immediately northeast of Branson; its overshooting tops began rapidly penetrating the anvil debris of the aforementioned storms at 0018 UTC.
The corresponding GOES-16 “Clean” Infrared Window (10.3 µm) images (below) revealed cloud-top infrared brightness temperatures cooling to the -75 to -79ºC range (shades of light gray to white) with these thunderstorms, significantly colder than the -68.5ºC tropopause temperature on the 00 UTC Springfield MO rawinsonde report (plot | text).
