   Areas affected...parts of northeastern Ohio into northwestern
   Pennsylvania

   Concerning...Severe potential...Watch possible 

   Valid 101241Z - 101445Z

   Probability of Watch Issuance...40 percent

   SUMMARY...A small organizing cluster may impact the I-80 corridor of
   northeastern Ohio into northwestern Pennsylvania through 10 AM to
   noon EDT, accompanied by small to marginally severe hail and gusty
   winds.  It is not clear that a severe weather watch is needed in the
   near term, but potential for stronger, more damaging gusts could
   increase later this morning, and trends are being monitored.

   DISCUSSION...A meso-beta scale cyclonic circulation has become
   better defined within a cluster of storms at least initially rooted
   above a shallow stable boundary layer.  Strong convection has become
   focused in a short narrow corridor to the east/southeast of this
   circulation, which is approaching the Greater Cleveland vicinity.

   Based on recent acceleration in forward (eastward) propagation in
   excess of 30 kt, the convective system appears likely to track
   across the I-80 corridor into northwestern Pennsylvania between
   Franklin and Du Bois by 14-16Z.  However, the boundary-layer across
   this region remains relatively stable, and this may only gradually
   begin to destabilize over the next few hours.  Westerly ambient mean
   flow in the lower to mid-troposphere also remains relatively modest,
   on the order of 20-30 kt, so the extent to which potentially
   damaging wind gusts increases in the near term remains unclear.
