The May 24, 2016 Jagodina landspout: Insights from Serbia’s most documented tornadic event

Abstract

The Jagodina landspout of May 24, 2016, is one of the most comprehensively documented tornado events in Serbia and provides valuable insights for the broader European context, where non-mesocyclone tornadoes are still underreported and insufficiently understood. Thanks to the unique contribution of an eyewitness from Jagodina, who recorded the entire event with photographs and video footage, it was possible to perform a detailed synoptic forensic analysis. Complementary documentation by the European Severe Weather Database (ESWD) further validated the occurrence and timing of the landspout (11:30 UTC ± 15 min). The event unfolded within a complex synoptic backdrop marked by a large-scale upper-level low and the support of an aloft jet streak, combined with a thermodynamically unstable mesoscale environment. Numerical values derived from radiosonde and model data showed moderate convective available potential energy (CAPE) (~405 J kg^–1), a negative lifted index (–3), dew point temperatures of 12-15 ºC, and temperatures near 20 ºC at the surface, pointing to significant instability. In addition, the presence of abundant low- to mid-level moisture, steep lapse rates, and small-scale convergence zones near the surface provided the critical boundary-layer forcing required for vortex initiation. This synergy of factors demonstrates that even in the absence of mesocyclone dynamics, relatively modest instability, when coupled with favorable surface processes, can produce a tornadic vortex. The Jagodina case emphasizes the necessity of integrating eyewitness documentation, synoptic-scale analysis, and numerical guidance to advance understanding and recognition of landspouts across Europe.
