"description": "A high-resolution weather prediction model was run from April 29 to May 31, 2024. This animation shows the simulated radar reflectivity and CAPE (convective available potential energy) – one of the key ingredients in the formation of severe convective weather, along with the model's helicity tracks and severe thunderstorm and tornado warning polygons issue by the NWS
Note the regions of convective precipitation formed along heightened CAPE values, igniting storms and causing most of the severe weather and helicity that occurred (regions of precipitation formed due to synoptic forcings are visible as well). Warning polygons remain on the animation for a 24-hr period.
Significant outbreaks occurred May 6-9, May 21, and May 23-26.",
