This trend may continue with organization into a bowing cluster with a locally enhanced risk for damaging gusts and a couple of tornadoes. DISCUSSION...As of 22 UTC, regional visible and radar imagery showed an increase in convective coverage associated with an MCV and remnant outflow boundary near the KS/NE border. Several stronger clusters have emerged this afternoon, with the strongest over Marshall, Clay and Riley Counties in KS. This cluster has shown some organization, despite limited vertical shear, with a bowing structure and a recent reports of damage and a funnel cloud. If it can remain near or on the warmer side of the boundary, this segment may continue to organize as it interacts with the boundary where local convergence is stronger. This may support a locally enhanced corridor of damaging wind and brief tornado potential from northeast KS into northwestern MO this evening. Additional convective development is ongoing on the southern flank of this cluster into central KS, which may support further upscale growth or a supercell or two. While deep-layer shear remains quite limited, the very moist air mass combined with locally stronger 0-1 SRH may support a brief/weak tornado hail or damaging gusts. An increase in the low-level jet this evening may allow for some organization or potential with any more persistent clusters this evening. ..Lyons/Guyer.. 06/04/2026 ...Please see www.spc.noaa.gov for graphic product...
