“…Other features, which may be potentially amenable to nowcasting, are small‐scale frontal squalls/tornadic events such as described by, for example, Clark (2012) and Holley and Members of TORRO (2022), or exceptional events such as the Ottery Storm (Grahame et al ., 2009; Clark, 2011).…”

High‐resolution models have brought about capabilities in forecasting that could barely have been envisaged decades ago. The same advances in computer power and atmospheric science that enabled successful high‐resolution modelling have also led to useful forecasts further into the medium range and beyond. However, there remain problems forecasting at very short range, in particular concerning convection, for which new products and techniques are being trialled at the Met Office. We examine how these latest developments present the forecaster not only with exciting opportunities, but also fresh challenges, in particular, interpreting the plethora of output now available, whilst adhering to tight operational deadlines.

“…Much disruption was reported to the road and rail network. Damage surveys conducted by members of TORRO and the public subsequently revealed a swath of widespread non‐tornadic wind damage ~20–25km wide and confirmed that several tornadoes had occurred (Holley et al ., 2022; Figure 11). As on 17 November 2016, the tornadoes were generally located towards the left (i.e.…”

Mesoscale cyclonic storms associated with tornadoes and localised wind damage in frontal rainbands

Ten cases are identified of an unusual type of mesoscale windstorm in the United Kingdom between 2006 and 2021. The windstorms, which occurred in association with frontal rainbands, produced wind damage swaths no more than 20–30km wide, but sometimes extending for several hundred kilometres, often with embedded tornadoes. Storm structure and evolution are explored for two cases using radar data, surface observations, a 1.5‐km gridlength model and damage reports obtained from social media platforms and post‐event damage surveys. Findings are summarised in the form of a conceptual model, and some questions are posed for future research.
