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.
