DISCUSSION...Several thunderstorms have recently intensified along a subtle surface boundary and in a zone of enhanced low-level convergence near a surface low in east-central CO. This activity is evolving along the eastern periphery of a large-scale ridge, where around 40 kt of effective shear is promoting convective organization (including supercells). These storms should continue tracking slowly southward along a buoyancy gradient, where a deeply mixed PBL will promote severe wind gusts over the next couple hours. Isolated instances of large hail will also be possible with the longer-lived supercell structures. ..Weinman/Thompson.. 08/21/2026 ...Please see www.spc.noaa.gov for graphic product...
