A large Mesoscale Convective System (MCS) initially developed over Nebraska and quickly grew in size as it propagated eastward across the Missouri River Valley region of the north-central US on 08 August 2010. AWIPS images of 1-km resolution POES AVHRR 0.63 µm visible and 10.8 µm IR channel data (above)... Read More

Severe thunderstorms propagated southeastward across far northeastern Montana late in the day on 26 July 2010. McIDAS images of GOES-11 (GOES-West), GOES-15, and GOES-13 (GOES-East) 10.7 µm IR data (above; each image set is displayed in the naive projection of the respective satellite) showed that a subtle “enhanced-v” storm top signature first...

Several days before the largest hailstone on record in the US fell in central South Dakota, McIDAS images of 4-km resolution GOES-13 10.7 µm IR data (above) showed a cluster of severe thunderstorms that propagated southeastward across far northwestern South Dakota on 19 July 2010. From a satellite perspective, this convection did not appear to be unusually intense... Read More

McIDAS images of GOES-13 and GOES-15 10.7 µm IR images (above) showed the development of severe thunderstorms that produced very large hail, tornadoes, and damaging surface winds (SPC storm reports) in central South Dakota on Read More
