   Areas affected...Parts of lower MI...eastern/central IN...and
   western OH

   Concerning...Severe potential...Watch unlikely 

   Valid 241822Z - 242045Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A few strong storms capable of producing locally damaging
   wind gusts are possible through the afternoon.

   DISCUSSION...A broken band of thunderstorms is moving eastward
   across parts of central lower MI, where subtle midlevel height falls
   are occurring ahead of a midlevel trough approaching from the west.
   While poor midlevel lapse rates and modest boundary-layer moisture
   (middle 50s dewpoints) are limiting buoyancy ahead of these storms,
   around 35 kt of midlevel south-southwesterly flow preceding the
   trough and steepening low-level lapse rates could support a couple
   strong/loosely organized cells/clusters capable of locally damaging
   wind gusts. While large-scale forcing for ascent decreases with
   southward extent, a similar environment may support a couple strong
   storms with an attendant risk of locally damaging gusts across
   central/eastern IN into western OH as well.
