Areas affected...southern Indiana...far southwest Ohio...and
northern Kentucky

Concerning...Severe potential...Watch possible=20

Valid 251957Z - 252130Z

Probability of Watch Issuance...40 percent

SUMMARY...A cluster of storms across western Indiana may produce
some damaging wind gusts across eastern Indiana, northern Kentucky,
and far southwest Ohio this evening.

DISCUSSION...The airmass ahead of a storm cluster in western Indiana
continues to destabilize with SPC mesoanalysis suggesting an
uncapped warm sector. As long as the airmass ahead of this cluster
continues to destabilize, at least some damaging wind threat is
expected to persist. Therefore, a severe thunderstorm watch may be
needed across southeast Indiana, northern Kentucky, and southwest
Ohio.=20

However, uncertainties remain. The outflow boundary from the morning
continues to move south and it is possible this will undercut the
storms which could weaken them. Visible satellite and the KIND
WSR-88D also show a showing trend of this outflow boundary slowing
over the past hour. Therefore, this boundary may provide the focused
corridor for the threat.=20

Additionally, some storms have developed along this boundary in
southeast Indiana. This is east of the greatest instability and
thus, these storms will likely remain below severe limits.=20

Trends of upstream convection and development along the outflow
boundary will be monitored for a potential downstream watch.
