   Concerning...Tornado Watch 700...

   Valid 161733Z - 161800Z

   The severe weather threat for Tornado Watch 700 continues.

   SUMMARY...Based on recent radar and environmental data, a strong to
   potentially intense tornado with potential peak winds of 110 to 155
   mph (EF1-EF3) is likely ongoing.

   DISCUSSION...Recent radar signatures from KPOE and KLCH as of 17:31z
   reveal an intense supercell characterized by a 0.5-0.9 degree
   rotational velocity between 61 and 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 4 and 5. Previous signatures within similar environments
   produced tornado-damage-estimated wind speeds from 110 to 155 mph
   and confidence is high for likely strong to potentially intense
   tornado. A tornado is ongoing and may continue based on the
   rotational velocity continuity and the storm moving within a
   favorable downstream environment.
