   SUMMARY...Ongoing supercell structure now to the northeast of the
   Stanton vicinity seems likely to weaken by around 9 PM EDT.

   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.
