During the afternoon of 23 October 2022, a mesoscale convective system (MCS) developed and intensified over the English Channel and tracked north-northeastward into southern England, producing widespread damaging winds and at least three moderate to strong tornadoes in Hampshire. In general, atmospheric temperature and moisture profiles from radiosonde observations and NOAA satellites indicated a high potential for severe thunderstorms, marginally severe straight-line wind, and tornado occurrence over southern England. Radar and satellite observations showed coincidental high rain rates and very low storm-top temperatures, as well as prominent trends in MCS organisation and intensity that suggested damaging outflow wind.</div>
