DISCUSSION...Scattered convection is developing along the eastern periphery of a remnant west-east oriented outflow boundary draped across portions of east-central Oklahoma into northwest Arkansas. Clear skies ahead of the boundary this morning amid a rich low-level moisture environment has led to rapid destabilization, with MLCAPE values approach 2500 J/kg. Weak flow aloft should limit storm organization, but some clustering of storms may occur with time during the afternoon as additional storms continue to develop along/near the boundary. Isolated damaging winds should be the primary threat, along with some potential for severe hail with the strongest cells. ..Karstens/Hart.. 06/30/2025 ...Please see www.spc.noaa.gov for graphic product...
