As a deep upper system propagated into the Central/Northern Plains, highly diffluent flow and an approaching upper jet streak aided in favorable conditions for convection along and ahead of a trailing cold front across portions of central into eastern Oklahoma. By the early evening of the 23rd, a lone supercell thunderstorm developed across east-central Oklahoma. This storm would produce reports of large to very large hail during it's slow southeastward march across the portions of the forecast area during the evening. Later that evening, more numerous organized (supercell) thunderstorms initiated across central into eastern Oklahoma, continuing to pose a large hail and wind damage threat. A well-organized supercell thunderstorm impacted areas in and around the community of Holdenville during late evening hours of the 23rd, leading to reports of significant wind damage and very large hail in/near the community.
