1-minute Mesoscale Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed the intensification of thunderstorms over far southwestern Missouri during the early evening hours on 19 July 2018. Surface outflow from these storms produced damaging winds (SPC storm reports), including a gust to 55 knots or 63 mph at Branson (plot | list) at 0025 UTC. Strong winds capsized a boat on Table Rock Lake — located about midway between Branson West Airport KFWB and Branson Airport KBBG (map) — resulting in 17 fatalities. The 0025 UTC image showed a new cell which had recently developed just northeast of Branson; its overshooting tops began rapidly penetrating the anvil debris of the earlier storm 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 both thunderstorms in southwest Missouri.
