   Areas affected...western/central North Dakota

   Concerning...Severe potential...Watch likely 

   Valid 160055Z - 160200Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Risk of severe storms with potential for large hail,
   damaging wind, and a tornado or two increasing into the evening.

   DISCUSSION...Supercells have developed across northern South Dakota
   and in western North Dakota this afternoon. Thunderstorm activity
   will increase this evening as a line of thunderstorms moves eastward
   out of Montana and additional thunderstorms develop along an
   eastward progressing cold front. These storms will be moving into an
   environment with favorable shear (40-50 kts 0-6 km) and instability
   (MLCAPE 2000-2500 J/kg) to support potential for a few discrete
   supercells and bowing linear segments capable of damaging winds,
   large hail, and a tornado or two. A watch will be needed soon to
   cover this threat.
