   Concerning...Tornado Watch 308...

   Valid 260316Z - 260415Z

   The severe weather threat for Tornado Watch 308 continues.

   SUMMARY...An intense supercell capable of producing a strong tornado
   is expected to continue for at least the next hour over far
   north-central Texas.

   DISCUSSION...Recent radar imagery has shown an notable increase in
   intensity of the supercell over Montague and Cooke County in far
   north-central Texas. Echo tops now over 60 kft, with a very strong
   low-level circulation observed as well. Recent mesoanalysis
   estimates that effective helicity is over 800 m2/s2 and effective
   shear is over 70 kt near this supercell. This intense shear coupled
   with very strong buoyancy (i.e. 4500 J/kg) is resulting in STP
   values from 16 to 18. Given the supercellular mode, a strong tornado
   is possible within this environment. An extension in time for
   Tornado Watch 308 may be needed.
