   Concerning...Tornado Watch 135...

   Valid 222253Z - 222330Z

   The severe weather threat for Tornado Watch 135 continues.

   SUMMARY...SUMMARY
   Based on recent radar and environmental data, a strong to intense
   tornado with potential peak winds of 130 to 165 mph (EF2-EF3) is
   likely ongoing.

   DISCUSSION...DISCUSSION
   Recent radar signatures from KGRK as of 2250Z reveal an intense
   supercell characterized by a 0.5 degree rotational velocity of at
   least 70 kt. A tornadic debris signature has also been noted on
   recent radar scans. These signatures are occurring in an environment
   characterized by STP between 5 and 6. Previous signatures within
   similar environments produced tornado-damage-estimated wind speeds
   from 130 to 165 mph and confidence is high for a strong to intense
   tornado. A longer-track tornado is ongoing and may continue based on
   the rotational velocity duration and the storm moving within a
   favorable downstream environment.
