Areas affected...Lower Ohio Valley

Concerning...Severe potential...Watch possible 

Valid 091742Z - 091945Z

Probability of Watch Issuance...40 percent

SUMMARY...A risk for damaging winds will evolve from eastward moving
outflow in the lower Ohio Valley. The coverage of strong/severe
storms is not clear, but a watch is possible this afternoon. Trends
will be monitored.

DISCUSSION...Outflow from convection associated with an MCV
northwest of St. Louis is moving eastward into the lower Ohio
Valley. As this boundary moves into an increasingly unstable airmass
with strong heating and mid/upper 70s F dewpoints, some
intensification is possible. The main risk for damaging winds will
likely occur south of the cirrus plume from the MCV. With the MCV
displaced to the northwest, shear/forcing enhancement will be
minimal. The degree of damaging wind threat will be tied to how
organized convection along the outflow boundary becomes. A watch is
possible if convective trends warrant.
