Areas affected…Eastern Kentucky

Concerning…Severe potential…Tornado Watch likely

Valid 021658Z – 021900Z

Probability of Watch Issuance…80 percent

SUMMARY…All severe hazards are possible this afternoon near an
outflow boundary in eastern Kentucky. A tornado watch is likely this
afternoon, though timing is uncertain.

DISCUSSION…Outflow from this mornings convection along the Ohio
River has sagged into east-central Kentucky and has appeared to have
stalled. With continued heating, MLCAPE of around 1000 J/kg is
possible by this afternoon. This outflow boundary should provide a
focus for additional storm development this afternoon in addition to
convection in central Kentucky moving eastward. Convection that can
organize and interact with the outflow boundary, most likely to its
south, will pose a risk for tornadoes, large hail, and damaging
winds. Regional VAD winds show low-level hodograph curvature. This
should improve with time as the 850 mb winds increase as the upper
low deepens. Winds are more backed (i.e. better low-level shear) to
the north of the outflow boundary, but destabilization is less
certain or at least will take more time to occur. A tornado watch
will likely be needed this afternoon, though the exact timing is not
