A Mesoscale Domain Sector was positioned over that region, providing images at 1-minute intervals; a comparison of “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (below) showed the development of this severe convection, which produced hail as large as 3.0 inches in diameter and 4 tornadoes (NWS Bismarck | NWS Grand Forks). The images include plots of SPC storm reports — just across the US/Canada border, storm reports in southern Saskatchewan/Manitoba can be seen here. Some of these storms exhibited very high radar reflectivity values, as shown here and here.
