   Concerning...Tornado Watch 107...

   Valid 122052Z - 122115Z

   The severe weather threat for Tornado Watch 107 continues.

   SUMMARY...Based on recent radar and environmental data, a strong to
   intense tornado with potential peak winds of 115 to 165 mph
   (EF2-EF3) is likely ongoing.

   DISCUSSION...An intense supercell will continue to move through a
   favorable environment over south-central Mississippi, characterized
   by 0-1 km SRH around 300 m2/s2 and MLCAPE near 2500 J/kg per latest
   mesoanalysis data. Recent radar signatures from KLIX as of 2044Z
   reveal an intense supercell characterized by a 0.4 degree rotational
   velocity between 60 and 69 kt. A tornadic debris signature has also
   been noted on recent radar scans. These signatures are occurring in
   an environment characterized by STP greater than 6. Previous
   signatures within similar environments produced
   tornado-damage-estimated wind speeds from 115 to 165 mph and
   confidence is high for likely 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.
