Wider weather episode

A shortwave trough approached the Missouri Ozarks on May 25, 2024, priming the atmosphere for moderate instability and sufficient deep layer shear. Additionally a low level jet around 45 to 50 knots nosed into the area during the late evening hours and into the early morning hours of May 26, 2024, further amplifying low level flow into the region. As a result, supercell thunderstorms developed and slid into the Missouri Ozarks during the overnight hours May 25 into May 26, 2024. These supercells produced hail between quarter and baseball size and flooding with rainfall totals between 3-4 inches. Widespread damaging winds were also observed, including a large swath of 70-80 mph winds in Barry county. Additionally, six tornadoes touched down across the Missouri Ozarks, producing damage ranging from EF-0 to EF-1 criteria.
