   Areas affected...Southern IN...Southwest into Central OH...

   Concerning...Severe potential...Watch unlikely 

   Valid 041511Z - 041715Z

   Probability of Watch Issuance...20 percent

   SUMMARY...An isolated damaging wind gust or two is possible across
   middle OH Valley for the next few hours.

   DISCUSSION...Recent surface analysis and visible satellite imagery
   reveals a complex environment in place across the middle OH Valley
   in the wake of a now decayed mesoscale convective system. Visible
   satellite imagery shows a mesoscale convective vortex about 15 miles
   northeast of BMG while surface observations and satellite imagery
   depict a remnant outflow boundary from about 10 miles north of EVV
   northeastward into central OH (about 15 miles south of MFD). Both of
   these features have already promoted new thunderstorm development.
   Currently, the overall environment is only modestly buoyant, with
   daytime heating needed to steepen low-level lapse rates and boast
   instability. Current expectation is for these loosely organized
   multicells/line segments to remain predominantly sub-severe with a
   relatively low potential for an isolated damaging wind gust or two.
   These features and the ongoing storms will likely both contribute to
   higher severe thunderstorm potential later this afternoon as the air
   mass destabilizes.
