Severe thunderstorms produce tornadoes, giant hail and damaging winds across parts of Texas and Oklahoma

1-minute Mesoscale Domain Sector GOES-19 (GOES-East) “Red” Visible (0.64 µm) images (above) showed supercell thunderstorms that produced tornadoes, hail as large as 4.25″ in diameter and wind gusts as high as 100 mph (SPC Storm Reports) across parts of Texas and Oklahoma on 08 June 2025. Frequent pulses of overshooting tops were apparent with these thunderstorms.

In the corresponding 1-minute GOES-19 “Clean” Infrared Window (10.3 µm) images (below), the coldest cloud-top infrared brightness temperatures associated with some of the pulsing overshooting tops were -80ºC or colder (shades of magenta embedded within bright white regions).

Many of these thunderstorms were moving into a broad corridor of enhanced instability and moisture that was in place from northern Texas into southern Oklahoma, as shown by GOES-19 CAPE (above) and Total Precipitable Water (below) derived products.
