 Mesoscale Discussion 1257
   NWS Storm Prediction Center Norman OK
   0246 PM CDT Sun Jun 25 2023

   Areas affected...Portions of far southeastern IN...far northern
   KY...western/central OH...and far southeastern Lower MI

   Concerning...Severe potential...Tornado Watch likely 

   Valid 251946Z - 252115Z

   Probability of Watch Issuance...95 percent

   SUMMARY...The potential for tornadoes, very large hail, and
   significant damaging winds will increase this afternoon as
   thunderstorms spread eastward. Tornado Watch issuance will be
   needed.

   DISCUSSION...Multiple supercells have developed this afternoon
   across IN, moving eastward towards western OH and vicinity. Very
   large hail of 2-3 inches in diameter has been observed with the more
   robust supercells, and the threat for very large hail should
   continue in the short term. The airmass across western OH is still
   destabilizing in the wake of earlier convection across KY. But with
   strong heating now occurring, along with a moist low-level airmass
   already in place, sufficient instability to maintain severe
   thunderstorms will likely exist into at least central OH. The
   tornado threat should gradually increase over the next few hours as
   a 25-35 kt southwesterly low-level jet overspreads this region, and
   as low-level hodographs lengthen and become more curved.
   Severe/damaging winds, with some potential for significant (75+ mph)
   gusts, will also be a concern as supercells merge into clusters and
   develop eastward in a strong deep-layer shear environment. Tornado
   Watch issuance will be needed soon to address this increasing severe
   threat.
