   Concerning...Severe Thunderstorm Watch 329...

   The severe weather threat for Severe Thunderstorm Watch 329
   continues.

   SUMMARY...The threat for severe wind and hail continues across WW
   329 and scattered storms move into eastern MT. These storms may
   impact portions of western North Dakota, and a downstream watch may
   be needed.

   DISCUSSION...Regional radar trends have shown an uptick in
   convection across northeast MT over the past hour, while a broken
   line of storms continues to the east across southeast MT. Despite an
   increase in MLCIN due to diurnal cooling, the environment remains
   favorable for organized convection with 40-45 knots of effective
   bulk shear and 1500-2000 J/kg of MLCAPE. Clusters of semi-discrete
   storms across northeast MT should continue to gradually grow upscale
   and shift the main hazard threat from hail to damaging winds over
   the next 1-2 hours. To the south, MRMS vertically integrated ice
   trends and IR imagery suggest that the broken line of storms has
   roughly maintained intensity and remains largely below severe
   limits. That being said, it should remain within the aforementioned
   favorable environment, so a brief re-intensification can not be
   ruled out over the next 1-2 hours. Trends will continue to be
   monitored as these storms move towards the MT/ND border, and a
   downstream watch may be warranted.
