   Areas affected...northern Ohio

   Concerning...Severe potential...Watch likely 

   Valid 120342Z - 120515Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Watch 320 was issued for the risk of damaging wind gusts.

   DISCUSSION...A mature MCS continues east this evening across
   northern Indiana and southern Michigan. This squall line will
   continue eastward along the instability gradient into the overnight
   hours. This squall line is likely near peak intensity now within the
   most favorable thermodynamic and kinematic environment. Temperatures
   are only in the mid to upper 70s across northern Ohio which will
   likely result in some weakening of the line as it moves east.
   Nonetheless, it will still pose a threat for damaging winds given
   the well-established squall line and at least moderate instability
   continuing into the overnight hours where dewpoints are in the upper
   60s to low 70s.
