   Mesoscale Discussion 0824
   NWS Storm Prediction Center Norman OK
   0641 AM CDT Wed May 24 2017

   Areas affected...Northeast Alabama...eastern Tennessee...northwest
   Georgia...eastern Kentucky

   Concerning...Severe potential...Watch possible 

   Valid 241141Z - 241415Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Storms should continue to gradually develop through the
   morning and early afternoon, with an isolated tornado, strong wind
   gusts and marginal hail possible.

   DISCUSSION...Storms are beginning to intensify ahead of a strong
   vort max aloft. Although instability is weak, it may be sufficient
   for at least isolated severe storms given cooling aloft and strong
   lift with deepening surface low. Visible satellite imagery shows
   extensive cloudiness is present downstream of these storms, which
   may temper their severity somewhat. However, as storms lift
   northeastward out of Alabama and across Tennessee and into Kentucky,
   some diurnal intensification is expected. Trends will continue to be
   monitored for a possible watch.
