   Mesoscale Discussion 0096
   NWS Storm Prediction Center Norman OK
   0934 PM CST Sat Feb 24 2018

   Areas affected...Kentucky and Tennessee

   Concerning...Tornado Watch 5...

   Valid 250334Z - 250500Z

   The severe weather threat for Tornado Watch 5 continues.

   SUMMARY...The risk for damaging wind gusts and isolated tornadoes is
   expected to continue with thunderstorms overspreading western into
   central Kentucky and Tennessee through 9-11 PM CDT.  A new tornado
   watch will probably be needed prior to the 03Z scheduled expiration
   of tornado watch 5.

   DISCUSSION...While the primary surface low development begins to
   take shape across portions of the Upper Midwest, the southern edge
   of elongated deepening surface troughing extending to the south is
   forecast to shift east of the Mississippi River into central
   Kentucky and middle Tennessee between now and 03-05Z.  This is where
   large-scale forcing for ascent is maintaining vigorous convective
   development, along and just south of a slow moving warm frontal
   zone.  In the presence of at least weak conditional instability, and
   strong to extreme low-level shear near a 50-70 kt 850 mb speed
   maximum, this may continue to support the evolution of low-level
   mesocyclones within stronger convection, accompanied by locally
   enhanced, damaging wind gusts and perhaps a couple of additional
   tornadoes.
