DISCUSSION...A sustained supercell structure has been maintained along a modest zone of differential surface heating to the north through northeast of Stanton KY the past hour or so. Deep-layer shear along this boundary appears rather marginal, and low-level hodographs, though exhibiting clockwise curvature, are rather small. However, near-surface buoyancy and potential upward parcel accelerations probably are being aided by a moist boundary-layer with dew points near 70F. Although this cell has probably produced one or two weak tornadoes, it is not clear that this will continue much longer, as the boundary-layer begins to stabilize with slow radiational surface cooling. ..Kerr/Thompson.. 05/26/2026 ...Please see www.spc.noaa.gov for graphic product...
