Areas affected...Central/eastern KY into southeast IN...southwest
OH...and northern TN

Concerning...Severe Thunderstorm Watch 588...

Valid 012215Z - 012345Z

The severe weather threat for Severe Thunderstorm Watch 588
continues.

SUMMARY...Some threat for damaging wind will move eastward into
early evening. Downstream watch issuance is possible.

DISCUSSION...A long-lived MCS currently moving across central KY
continues to show signs of organization, with a well-defined cold
pool and evidence of a relatively strong rear-inflow jet from
regional VWPs. However, recent measured gusts have generally been
subsevere, in the 35-45 kt range. While relatively weak low-level
flow and deep-layer shear may continue to limit severe-wind
potential to some extent, very warm, moist, and unstable downstream
conditions (with MLCAPE of 2000-3000 J/kg) will continue to support
a threat of at least isolated damaging wind as this MCS continues
eastward into the early evening. As the MCS approaches the eastern
edge of WW 588, downstream watch issuance will be possible,
especially if there is any uptick in measured gusts and/or overall
organization and intensity of the system.
