Areas affected...Portions of far southeastern IN...northern/central
KY...and southern/central OH

Concerning...Severe Thunderstorm Watch 545...

Valid 250030Z - 250200Z

The severe weather threat for Severe Thunderstorm Watch 545
continues.

SUMMARY...An isolated severe threat should continue in the short
term. But, additional watch issuance is not expected this evening.

DISCUSSION...Convection across parts of northern/central KY has
generally evolved into loosely organized clusters over the past
couple of hours, with around 30 kt of deep-layer shear noted on
recent VWPs from KLVX sufficient for modest updraft organization.
Occasional strong to damaging winds should remain the primary threat
with this activity over the next hour or two as it moves slowly
east-southeastward into eastern KY. Thunderstorms across parts of
western into central OH have maintained a somewhat more discrete
character, with slightly stronger mid/upper-level flow supporting
around 30-40 kt of effective bulk shear. Isolated severe hail will
remain possible with these marginal supercells and multicells in the
short term, in addition to some threat for strong/gusty winds.  All
of this activity is forecast to slowly weaken over the next couple
of hours with the loss of daytime heating, and as convection spreads
into a less unstable airmass. Accordingly, additional watch issuance
is not expected this evening.
