Areas affected...eastern Kentucky

Concerning...Severe potential...Watch unlikely

Valid 121744Z - 121945Z

Probability of Watch Issuance...20 percent

SUMMARY...Marginal severe risk to continue through the afternoon.
Downstream watch unlikely.

DISCUSSION...A line of thunderstorms currently moving across
northern Kentucky has trended downward in intensity in the last
hour. Surface based CAPE has become meager around 100-200 J/kg ahead
of the eastward advancing line. There is some indication in recent
HRRR runs that a line storms developing currently across middle
Tennessee could increase in coverage and track northeastward into
portions of eastern Kentucky by around 22z. Areas along the eastern
Kentucky/Tennessee border may see marginal recovery, with RAP
analysis showing around 500 J/kg ahead of the potential secondary
line of storms. A brief uptick in activity could be possible by the
afternoon as increased flow aloft (around 45-55 kts at 850 mb)
continues to keep shear profiles favorable for a few pulse severe
storms. Watch issuance is unlikely.
