   Mesoscale Discussion 0097

   0959 PM CST Sat Feb 24 2018

   Areas affected...Middle Tennessee...eastern Kentucky and parts of
   adjacent southern Ohio and West Virginia

   Concerning...Tornado Watch 6...

   Valid 250359Z - 250530Z

   The severe weather threat for Tornado Watch 6 continues.

   SUMMARY...A risk for severe weather continues, but this threat is in
   the process of becoming increasingly marginal, and a new watch is
   not anticipated.

   DISCUSSION...Overall, even the most vigorous convection is becoming
   generally low-topped as associated large-scale forcing for ascent
   spreads toward the upper Ohio Valley/central Appalachians. 
   Lightning has diminished considerably further in the past couple of
   hours, and these trends seem likely to continue into and through the
   1-4 AM EST time frame.  Although the surface warm front has advanced
   into the vicinity of the Ohio River, the boundary layer ahead of the
   convective line becomes progressively cooler and drier eastward into
   the Cumberland Plateau.  Further potential for tornadoes seems
   rather limited, but downward mixing of stronger momentum could
   continue to contribute to sporadic damaging wind gusts at least
   another couple of hours.
