   Mesoscale Discussion 2008
   NWS Storm Prediction Center Norman OK
   1153 PM CST Fri Dec 10 2021

   Areas affected...Portions of northern Kentucky.

   Concerning...Tornado Watch 554...

   Valid 110553Z - 110700Z

   The severe weather threat for Tornado Watch 554 continues.

   SUMMARY...A strong tornado threat continues across portions of
   northern Kentucky.

   DISCUSSION...Storm interference from new cells merging has finally
   disrupted the persistent very strong low-level mesocyclone with the
   long-lived supercell now entering Breckenridge County, Kentucky.
   However, while this has weakened the intensity of the updraft and
   low-level rotation, a strong tornado with around 50 to 55 knot Vrot
   and a TDS is still present. Mid 60s dewpoints have advected ahead of
   this storm and therefore, adequate instability remains for strong
   tornado development given the 350 to 400 m2/s2 0-1 km SRH per the
   KLVX VWP. Therefore, while circulations may be weaker and more
   transient, a strong tornado threat persists.

this thing still, and i literally mean still as of 1:20am EDT, has a debris ball on it. just a beast of a storm.

This is one of those nights that you as a weather fan talk about for the rest of your life.  One of those hallmark nights.  Unfortunately for the wrong reasons tonight.
