Areas affected...southern OH

Concerning...Severe potential...Watch unlikely 

Valid 300623Z - 300800Z

Probability of Watch Issuance...5 percent

SUMMARY...A brief tornado and localized damaging wind threat may
persist for a another hour or two with a cluster moving
east-southeast across a portion of southern Ohio. Overall threat is
expected to subside before dawn.

DISCUSSION...A cluster intensified last hour over southwest OH with
at least one TDS noted just southwest of the ILN radar into Clinton
County. A surge in IR cloud top cooling occurred just before this
TDS and has since warmed, but transient mesovortices remain possible
along the leading edge of the gust front. While there is adequate
low-level shear in the ILN VWP data, weaker flow with minimal change
in direction has persisted above 1 km AGL, suggesting long-term
organizational potential will be limited. Downstream buoyancy is
increasingly meager with eastern extent (below 500 J/kg) as this
cluster progresses east-southeast at around 35 kts. As such, the
brief tornado/localized damaging wind threat will probably diminish
after about 08Z.
