   Mesoscale Discussion 0214
   NWS Storm Prediction Center Norman OK
   0836 PM CDT Thu Mar 19 2020

   Areas affected...north-central into northeast AR

   Concerning...Tornado Watch 56...

   Valid 200136Z - 200330Z

   The severe weather threat for Tornado Watch 56 continues.

   SUMMARY...The greatest tornado risk through late evening will likely
   focus from north-central AR into northeast AR.

   DISCUSSION...Radar mosaic shows a strong supercell located in
   north-central AR as of 830pm CDT.  Analysis of KLZK and KNQA VAD
   data indicates the wind profile is strengthening with the low-level
   hodograph enlarging.  The enlarging of the low-level hodograph is
   especially evident over the past 1-2 hours at Memphis with 0-1km SRH
   increasing from 400 to 500 m2/s2.  With the cluster of storms over
   north-central AR moving northeast relatively unimpeded on the
   northern periphery of the weakly buoyant/moist sector (500 J/kg
   MLCAPE from the 00z Little Rock sounding), expecting some continued
   risk for a tornado or two for the next several hours as this storm
   cluster moves to the northeast.
