The Severe Weather and Tornado Outbreak of April 19, 2023

A broad, longwave trough was present (aloft) across the western-half of the continental United States (CONUS) on April 19, 2023. At the surface, a low-pressure center was slowly organizing/strengthening across portions of central Kansas, with a dryline extending southward towards west-central Texas. Plentiful insolation across much of the area, combined with increasing near-surface moisture, lead to the development of an unstable boundary layer (high amounts of surface-based instability) favorable for severe weather.

The greatest forecast challenge with this event was whether storms would develop due to a strong cap (layer of warm air) aloft. Additionally, if a few storms did ultimately develop, would they be “surface-based” (i.e. capable of producing tornadoes & damaging winds)? The 1900 UTC/2:00 PM CDT special balloon release from the office revealed that the cap was much weaker than expected by the early afternoon. Combined with a deep dryline circulation, along with passage of well-timed shortwave across this boundary, a few robust supercell thunderstorms developed across central Oklahoma into the evening.

Multiple instances of large to very large (2 inches) hail were observed with the most dominant supercells into the evening hours. The largest observed hailstone during the event was 3 inches (teacup sized) near Amber, OK (Grady County) and Newcastle, OK (McClain County). By early evening, as the low-level jet began to intensify, a pair of supercell thunderstorms became tornadic. The first tornado with this event produced light (EF-0) damage near Tinker Air Force Base. The most damaging and deadly storm of the day rapidly organized across McClain County by 7 PM CDT. An intense (EF-3) tornado did extensive damage in/near the town of Cole, OK, with 3 “satellite” tornadoes (of EF-1 strength) observed near the path of the “Cole” tornado. This storm went on to produce 7 additional tornadoes, including multiple significant (EF-2+) tornadoes across Cleveland and Pottawatomie counties. Another notable tornado, with widespread impact, affected western portions of Shawnee, OK late in the evening. Another interesting aspect of this event was that, given the presence of a strong low-level jet along with slow storm motions, tornadoes tended to track to the north and west with time during their lifespan.
