Mesoscale Discussion 0728

   Areas affected...Southeast Oklahoma and western Arkansas

   Concerning...Severe potential...Watch possible 

   Valid 252039Z - 252215Z

   Probability of Watch Issuance...60 percent

   SUMMARY...There is an increasing tornado threat across southeast
   Oklahoma and western Arkansas over the next 1 to 2 hours.

   DISCUSSION...Several mini supercells have developed in eastern
   Oklahoma over the last 30 minutes with evidence of organizing
   mid-level rotation. 0-1 km SRH has now increased to near 175 m2/s2
   per KSRX VWP with MLCAPE around 1000 to 1500 J/kg. This should
   support a continued threat for strengthening low-level rotation and
   potentially an increasing tornado threat through the afternoon and
   into the early evening. Given the latest radar trends and slightly
   higher low level SRH than earlier, watch probabilities have
   increased. Radar trends will be monitored over the next hour and a
   tornado watch may be needed soon if trends continue.
