Areas affected...central KY

Concerning...Severe potential...Watch unlikely

Valid 230106Z - 230130Z

Probability of Watch Issuance...5 percent

SUMMARY...Low-topped mini supercell structures will likely be
short-lived across central KY.

DISCUSSION...Radar imagery from KLVX and KOHX shows several weakly
rotating marginal supercells across central KY as of 0045-0100Z.
The 00Z BNA raob sampled what is likely a regionally greatest
corridor of instability with MLCAPE around 400 J/kg and a lowest 100
mb mean mixing ratio around 9 g/kg.  The long and curved low-level
hodograph is favoring quasi-discrete storms but the overall weak
buoyancy coupled with the loss of heating will likely limit overall
thunderstorm intensity and any low risk for localized severe.
Nonetheless, will continue to monitor thunderstorm development
before this activity moves to the east/northeast of the
instability/moisture axis as it moves from the I-65 to I-75 corridor
during the next 1-2 hours.
