Widespread severe weather brought large hail, damaging winds, and tornados to two areas of the central US on 27 April 2021: Eastern Colorado and central Texas. Given the expected weather, two GOES-East mesoscale sectors were positioned over the region, with a slight N-S overlap in the middle. A simple AWIPS procedure allows one to view […]

A severe thunderstorm traversing almost the full length of Nebraska from west to east just south of I-80 produced landspout tornados and numerous instances of hail > 1″ in diameter. The evolution of the storm during the afternoon into the overnight hours is captured well in a VIS/IR combo product, which transitions from the VIS/IR […]

Strong thunderstorms developing across west Texas on 09 April 2023 resulted in damaging wind gusts and large/accumulating hail. Early satellite analysis by NWS LUB summarizing some of the forcing that would be at play: “Water vapor imagery shows a weak, positively tilted trough working through the forecast area now. An outflow boundary from early morning […]

A quick moving shortwave and ample moisture resulted in widespread severe thunderstorms across the high plains on 7 June 2022. The shortwave trough is obvious in GOES-East water vapor imagery digging across the Rockies during the morning, and east into the plains after convective initiation during the afternoon/evening (Fig 1). Thunderstorms developing across the southern […]
